Polycarbonate Lenses Eyeglasses

June 18th, 2015 by admin No comments »

Polycarbonate lenses eyeglasses are eyeglasses with lenses made of polycarbonate, a durable, cheap plastic. Polycarbonate was developed in the 1950s and was soon recognized as a dynamic substitute for glass. In the 1980s, polycarbonate glasses were introduced to consumers as a safe, affordable alternative to standard plastic or glass eyeglass lenses.

Polycarbonate lenses have significant benefits over other forms of lenses on the market. In addition to their excellent impact resistance, polycarbonate glasses are up to 40% thinner and one-third lighter than standard plastic lenses. These properties make polycarbonate glasses ideal for people with high prescriptions. Polycarbonate glasses, however, are not perfect. As a result of their ability to absorb impact, the lenses are soft and therefore more susceptible to scratches. To compensate for this, scratch-resistant coatings have been developed and can be added to polycarbonate glasses to provide added durability. All safety eye wear is made from polycarbonate material as it provides the best impact resistance of any eyeglass materials available. Polycarbonate glasses are 10 times more resistant to breakage than plastic lenses. Lenses made of polycarbonate are highly recommended for children due to this safety benefit. Additionally, polycarbonate blocks 99% of UV light. This ability is an important feature, especially for children and individuals who work outdoors, as UV light is known to contribute to the development of cataracts.

Polycarbonate lenses are favored by athletes and by parents of young children because they are designed to not shatter when they receive a blow. Instead polycarbonate lenses are engineered to crack in a spiderweb pattern to prevent shards from the damaged lens from injuring the eye. Polycarbonate lenses are can be coated to help prevent scratching. But no matter how careful you are, occasionally even coated lenses may get scratched. Once your polycarbonate lenses were scratched, squeeze a dime sized amount of regular toothpaste onto a clean, soft, cotton cloth. Rub the toothpaste onto the scratched surface of the polycarbonate lens in a circular motion for ten to twenty seconds. Then dampen a clean, soft, cotton cloth in cool water. Rub the wet cloth over the lens to remove all of the toothpaste. Next, you need to dry the lens with a dry clean, soft, cotton cloth. Examine the lens to determine whether the scratch has been completely removed. Deep scratches or multiple scratches may require this procedure to be repeated.

Tortoise glasses or tortoise shell glasses, in a commercial sense, are made of plastic with a mottled brown, black and sometimes orange patterns. Tortoise shell bases its design on the shell markings of the hawksbill turtle, and initially it was made from the turtle.

Tortoishell was a heavily used natural material made popular in the early 1900’s. The most widely used was the hawksbill turtle because of the excellent hues and how well the tones reflected on people skin. Many items were fashioned from the tortoishell and the use became outlawed in the 1970’s to protect this species of reptile from endangerment. The tortoishell could be manipulated to make items such as hair clips, guitar picks and eyewear. The tortoise shell eyeglasses became popular in the 1900’s first made famous by comedian Harold Lloyd. This eccentric thick dark round eyeglass was a diversion from the classic metal eyeglasses mostly fashioned in this time period. The time had come for change this was the revival needed for eyeglasses, they were becoming a fashionable and sought after statement. No longer just a medical device allowing one to see clearly, eyeglasses were clearly becoming fashionable.

Since tortoise shell glasses are more popular, how to wear it? You can wear your tortoise shell glasses with any casual outfit. Wear a hat, jeans and tee for a cool and casual day look. Wear your tortoise shell frames with khakis and a polo for a cool and preppy look. Whether you are golfing or boating or just cruising the mall, tortoise shell eyeglass frames are perfect. Moreover, choose a color to compliment your skin. If you are lighter, go for brown tortoise shell frames. If you have a darker skin tone, opt for the black or dark brown frames. You can wear tortoise shell frames as reading glasses or sunglasses. More importantly, try on a variety of styles to find the right frames for your face shape. There is a frame shape and price for every budget. You don’t have to spend a fortune on your tortoise shell eyeglass frames to look amazing.

Wood glasses

June 18th, 2015 by admin No comments »

Wood glasses are just what the name implies. Glasses created from a variety of wood, which add a distinctive beauty to the entire eye glass frame. Different types of hardwoods can be used including pine, walnut, oak, and countless others to play with color and texture, even though they’ll be sanded and polished. It is common knowledge that plastics, various metals and alloys can be applied in the product of eyeglasses frames. It is rarely that the wood can be made of eyeglasses. The unexpected combination of natural elements and glass lenses make wood glasses unique and unparalleled.

Wood glasses can work on anyone as there are so many different colors and styles available. You do not have to go for super exotic pattern of zebra wood or create high drama in burgundy-stained, polished wooden eyeglass frames unless that’s your personal style. Both of these looks can be stunning if that’s who you are. But, if the way you roll is more rustic or understated, then wooden eyewear frames are still going to be a good choice because you can also find subtler grain patterns and toned down, natural wood colors. Either way, the main advantage of wood eyewear frames, other than being super sturdy and eco-friendly, is to let your true personality stand out.

Celebs such as Will Smith and Catherine Zeta Jones enhance their personal style with wooden frames and you can do the same. You may want to think of it as being your own dresser. No, you won’t be getting paid to make some movie star look fabulous, but it’s something great to do for yourself to be a star in your own life. Who knows, you may even end up getting paid back in compliments for the extra time you took to choose those flattering, new prescription glasses or sunglasses with wood frames for yourself. Your goal should be to choose wooden eyewear frames that you really love and that make you look your absolute best. Before you settle on a specific wood eyewear frame, take the time to look at the different colors and textures available first. Chance are, if you really love a wood’s color and look, you’re going to be able to carry it off wonderfully. Don’t get distracted so much by the names of the different woods such as whether the eyewear you want will be zebra wood, birch, bamboo, ebony, pear or another variety, but instead keep an open mind as you browse wooden eyeglass frames and let your heart guide you as you react to each frame you see. If you fall in love with several different frames at once, just narrow things down later by picking the one that suits you best. You and your new wood eyewear frames are then destined to live happily ever after. Cue the cooing doves.

The overall style of your glasses is also going to make a difference in how the wood frames look on you such as whether you opt for a modern, vintage or classic style. Most of us are going to look good in more than one main style, so you may want to spice up your eyewear wardrobe and go for something different than the same basic lens shape and frame combination you usually choose. Keep it real and bring out your own personality though, or it’s just not going to work. We are not all Cee Lo Green or Tom Cruise, yet all still have the potential of looking amazing in glasses. Another part of the whole to keep in mind when putting together a wood-framed eyewear look is the color of the lenses. This is going to be mainly a factor when picking sunglasses with wood frames, but you may want to consider tinted lenses for daily wear as well. If you’re still having trouble deciding on a wood frame and lens combination, try describing the overall look of the eyeglasses to yourself in one word such as “sporty,” “trendy” or “creative.” If the words “not me” come up in your brainstorming, then move on to another combination. The right wood eyewear frames are going to be out there for you.

about Titanium eyeglass frames

June 18th, 2015 by admin No comments »

Titanium eyeglasses frames are made of titanium, which is one of the strongest materials available. They are lightweight, durable and corrosion resistant and a great choice for those in hot, humid environments. Moreover, they are also a good choice to people with active lifestyles and those with prescriptions that require thicker lenses. Titanium eyeglasses frames come in variety of colors and are easy to adjust, without sacrificing strength. Generally, there are four main benefits and features of titanium eyeglasses frames.

First of all, they are durable. For a people who want trouble-free service from a pair of eyeglasses, titanium is the right choice. In fact, titanium resists breakage under normal use longer than any other frame material. While these eyeglasses are surely not indestructible, patients are attracted to the fact that titanium frames hold up over time. In addition, titanium frames are corrosion resistant. If you are an eyeglass wearer, you know that after time, with traditional metal frames oxidation occurs through exposure to oxygen and the presence of moisture which can ruin the appearance of the frame causing it to tarnish.

Secondly, frames made of titanium are 48% lighter in weight than frames made of conventional metals. If you have worn a heavy pair of eyeglasses, you know that they can cause pressure on the bridge and the side of the nose. This can cause numerous problems such as simple redness to pressure spots and sores. The same is possible behind the ears, especially on the tops and behind the ears where the weight distribution is critical. The lightness of titanium frames lets the eyeglasses rest easily on the nose so they do not create irritating dimples or pressure marks.

The third benefit is comfort. A frame touches a person’s face in three areas-both ears and the nose. Titanium frames are more comfortable to wear because they do not weigh heavily on these essential areas. The weight is distributed more evenly providing added comfort.

Finally, if you are in the 10% of the population that is allergic to nickel, titanium frames are the best choice for you. Allergic reactions from nickel can range from asthma, sinusitis, skin rashes, eczema and dermatitis. Titanium frames contain no nickel, which is why they are an excellent choice for those who have skin allergies.

Even though titanium is a strong, light and corrosion-resistant silver-colored metal. Care should be taken when working with and repairing a titanium frame.

Clean and dry both the frame and lenses. Use soapy warm water to wash and dry the lenses and wipe with a soft cloth or towel. Do not use paper towels on lenses. Remove any remnants of old glue if a previous repair has been done.

Squeeze together any hinges that have spread out by gently using pliers to compress each side of the hinge. Use caution and squeeze very slightly; only light pressure is needed to move hinge pieces. Insert and replace the temples, also called the “arms,” if they have become detached from the front of the frame.

Insert the lenses if either or both have come out. Secure screws just tight enough to hold the lenses in place. If necessary, dab a drop of glue with a toothpick into the eyewire, the part of the frame that holds the lenses in place, to stabilize the lenses.

Tighten any loose screws in the frame. Screws may be located in the temples, the eyewire, and there may also be screws in the nosepads that hold the pads to the frame.

Do not try to solder or weld a titanium frame. Repairs done this way will crack and damage the frame material. If your titanium frame is broken to the point of needing soldered, an optical retail shop may be able to fix the frame or send your frame to a lab that specializes in titanium repairs.

about pilot sunglasses

June 17th, 2015 by admin No comments »

Sunglasses are important protective devices for pilots. Pilot sunglasses can reduce visual fatigue, thereby reducing the possibility of pilot error. A good pair of sunglasses can also protect the eyes and vision from ultraviolet radiation too. For a pilot, choosing sunglasses is a difficult task because of the variety of types available and because marketing often addresses fashion rather than performance.

Actually, choose the type of pilot sunglasses will depend on your aircraft, the environment in which you fly, and your personal preference. Moreover, the features which are important in choosing sunglasses for flying can be considered as filter factors and frame factors. When it comes to filters, the total light transmittance should be taken into consideration, because Light striking the front of the filter can be reflected or absorbed, or can pass through the filter. The amount of light passing through the filter is called the transmittance, and the smaller this number, the stronger/darker the filter. For pilots, the optimal transmittance is 16% to 20%. Below 15% there is reduced visual acuity and color discrimination, even with neutral density filters. A filter with no tint is described as a neutral density filter. This reduces the total light incident on the eye, while preserving the relative proportion of different wavelengths Neutral grey is the best general purpose tint for flying, as this produces a neutral density filter. A filter with a tint will appear to be colored when held up to light. This is because it is absorbing the other colors in the spectrum. A green filter appears green, for example, because it is absorbing red and other wavelengths of light. The second factor is UV protection. UV (ultraviolet) light is harmful to the eyes and to the surrounding skin. It is a risk factor in cataract, age-related macular degeneration, and skin cancers. The intensity of UV radiation increases by 4% per 1000 feet of altitude. Stratospheric ozone shields the earth’s surface from UV light. Low altitude flight in geographical regions where the ozone layer is depleted, and flight in or above the ozone layer anywhere in the world, both carry an increased risk of UV damage. Flying over snow, sand and water increases UV exposure, as UV light is reflected. It is recommended that all pilot sunglasses block 100% of UVA, UVB and UVC. The last factor should be taken into consideration is polarizing filters. These work by selectively blocking plane polarized light. Light becomes plane polarized when it is reflected towards the observer. These glasses are therefore excellent for dealing with situations where large amounts of light is reflected from surfaces such as snow, sand or water. However, aircraft windscreens are often either intentionally or unintentionally polarized in the manufacturing process. When a wearer looks through the windscreen, they see Moiré patterns. These are interference patterns caused by interaction of two sets of polarized filters. Moreover, Some LCD displays emit polarized light. These displays can dim or disappear when the pilot rotates their head to look at them. Polarized sunglasses are, however, useful for seeing submerged objects in water. They therefore have limited, specific applications in aviation, such as fixed wing open cockpit or rotary wing doors off, for a crewmember or pilot non-flying looking out of the aircraft.

about Tinted Glasses

June 17th, 2015 by admin No comments »

Tinted glasses are eyeglasses lenses tinted by applying absorbent coatings through the process of vacuum deposition. These thin coatings consist of metal or metal oxide mixtures and can be vacuum deposited only at certain high temperatures. They also have a high refractive index, meaning that they increase reflectance. They are deposited in multiple layers so that the properties of the glass remain intact. Due to the tinting of the metal or metal oxide mixtures, these lenses are available only in brown shades of different levels of absorption. Almost all plastic lenses are tinted in a special dye bath. To do this, several lenses are mounted on special holders and then immersed in the bath. While the eyeglass lenses are in the immersion bath, the dye particles penetrate to about 0.1 millimeter beneath the surface of the lens and become firmly embedded in it. Each immersion basin is equipped with a magnetic agitator to ensure that all eyeglass lenses are tinted evenly. The dye substances used also have applications in the textile industry. It is possible to match every color sample provided, tinting plastic lenses in any conceivable color and light reduction level based on the primary colors of red, yellow, and blue. Lenses with gradient colors can also be produced with special equipment, allowing for a gradual tint transition from light to dark by subjecting the eyeglass lenses to a predetermined exchange speed. This means that it is not only possible to pick out eyeglass frames, but also the tint of the lenses, resulting in eyeglasses with a personalized optical design, even if this means that not all colors can be perceived in their original shade.

Each color of lens is suited for specific situations. You will notice that many of the color properties overlap with each other. Whether they are performance, therapeutic, or fashion tints, each color causes the patient to perceive their surroundings differently. The most common tinted lens color is grey. At its darkest it can hide a poker face, help a deep sea fisherman snag the catch, and improve visual performance when driving. Grey lenses are color neutral, which means that they do not distort the integrity of colors, keeping them true. In fact, grey lenses have been in use by the U.S. Military for over 45 years because of their superior performance in various lighting conditions.

Some people prefer a grey/green lens to the traditional brown, citing that it provides crisper contrast, while being more color neutral than brown.

Brown/Amber lenses are also a popular choice. They provide better contrast and depth perception than grey, but colors are distorted. Brown/amber lenses are great for bright light conditions, but are especially suited to overcast, hazy, or foggy conditions. They block out blue wavelengths, which highlights the differences in greens, which can be helpful for golfers and baseball players.

Individuals who do a lot of driving would benefit from yellow lenses. The added contrast will decrease fatigue and increase visual acuity when driving in fog or haze, in overcast conditions, and at evening/night. For these same reasons, bikers, pilots, tennis players, hunters, and sport shooters can benefit from this lens.

Orange lenses eliminate blue light. They are perfect for sports that require an object to be tracked against the blue sky, such as a baseball. These lenses are often the lens of choice for clay target shooting on a cloudy day, but can also be helpful to bikers, skiers, and hunters.

Vermilion is a reddish/orange lens often used by individuals who like to hunt and fish. It is chosen for its contrast capabilities. There are patients who are more satisfied with this color than with the more common brown and grey.

Red is a robust color that provides contrast and is another variety best suited for specific purposes. Clay target shooters may use this color in extremely sunny conditions. Fishing enthusiasts may opt for this lens when fishing in the early morning or later evening.

Violet deserves mention as more than a fashion tint. Sport shooters and other athletes will use it for contrast in mid to bright conditions. Fashion tints are generally tints applied for the appearance of their color rather than any traits of that color. Common examples of fashion tints are green, blue, pink, and purple.

Tints of any purpose can be applied as a solid tint, causing the lens to be one solid, uniform color, or a gradient tint, when the intensity of the color lightens as it approaches the bottom of the lens. Double gradients and other color designs can be applied. For rimless or semi-rimless frame styles, edge tinting is also an option.

about protective goggles

June 16th, 2015 by admin No comments »

Protective goggles are form of protective eyewear that usually enclose or protect the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes. They are used in chemistry laboratories and in woodworking. They are often used in snow sports as well, in cycling and in swimming. Goggles are often worn when using power tools such as drills or chainsaws to prevent flying particles from damaging the eyes. Many types of goggles are available as prescription goggles for those with vision problems, such as driving goggles, swimming goggles, ski goggles and so on. Take swimming goggles for example, it must be watertight to prevent water, such as salt water when swimming in the ocean or chlorinated water when swimming in a pool, from irritating the eyes or blurring vision. Allows swimmers to see clearly underwater. They will not be usable more than a few feet underwater, because the water pressure will press them tightly against the face.

The history of swimming goggles dates back at least to the 14th Century, when writers described Persian pearl divers using goggles with windows made of the polished layer of tortoise shells. That these goggles were possibly imported to Mediterranean countries can be deduced from the 16th Century illustration of Venetian coral divers using goggles. Goggles mysteriously disappeared from use, possibly because enslaved American Indian and African divers, who did most of the world’s commercial diving from the 16th Century onward, did not use goggles. Polynesian skin divers were known to use bamboo or goggles carved of wood. Originally, these wooden goggles had no lenses, but trapped air when the face was down, forming an air bubble over the eye that enabled the divers to see clearly when submerged. With the introduction of glass, the Polynesians added lenses.

If you are a novice, choosing the best swimming goggles for your needs can be a frustrating experience if you do not know what to look for at the sports store. It is advisable that you try on the swim goggles you are interested in, ideally the exact pair that you’ll be buying. Nothing is more frustrating than having bought a new pair of goggles that is uncomfortable or useless because it leaks. Now push the lenses some more against the eye sockets, then release them. The goggles should stick on your face a few seconds thanks to the suction, even if the straps are off. If this isn’t the case and the swim goggles fall off, they will leak water and be useless. If the goggles pass the first two tests, put the straps on and see if the goggles are still comfortable. Check if the lenses don’t suck too much on the eyes or that the straps must not be tightened too fast.
