August 25th, 2010 by Connie Robertson No comments »

Sunglass and eyeglass designers always work hard to make their products appear in various ways. Providing a wide variety of eyewear styles can maximize the satisfaction of customers with different tastes. One special category of products in the sunwear world is funny sunglasses. It is easy to understand that they refer to sunwear products that look funny and cute. Creating such an effect relies mainly on the frame shape or structure. Sunglasses are largely a unique form of accessory and thus allow free and bold designs. Their frames can take use of any possible shape. Of course, various colors have been widely applied to sunglass lenses in recent years. The utilization of attractive colors certain enhances sunwear charm, but they are not directly associated with a funny look. Currently, funny sun glasses coming in funny shapes are available in quite a wide variety. They can be either mild or dramatic.

Funny sunglasses are available in lots of mild designs. Heart shaped sunglasses have been brought into existence for many years. Taking this style brings the look of love into the wearer’s eyes. And in most cases, a red color will be applied to the frame. Cat eye sunglasses have a frame that is similar in shape to a cat’s eye. These items were quite popular in 1950s in the United States. And now they appear as a type of retro sunglasses. Mr 50s black sunglasses are now commonly thought to be funny, even they were once a time considered as a formal style. 60s gold rimmed round novelty sunglasses are sold also as retro sunwear. Their appearance is quite unique and cute.

A funny look can also be created by some dramatic sunglasses that use unusual shapes. Funny sunglasses of this type perform well especially in special festivals or parties. In some cases, they are called party sunglasses. Margarita party sunglasses use drink shaped frame and the lenses are normally made with appropriate UV protection. They will bring exciting entertainment during celebration parties. Another example is Happy Birthday sunglasses, which have small candles on top of the frame. Designers of funny sun glasses have made many other funny frames available.

Materials for metal sunglasses

August 24th, 2010 by Connie Robertson No comments »

Frame material is quite critical that it should be carefully considered by every customer while shopping for eyeglasses, sunglasses or protective glasses. Prescription eyeglasses, UV sunglasses and safety goggles are generally for different purposes and vary in frame and lens designs. For instance, these different eyewear types may use regularly different lens and frame materials since related customers have specific requirements. Protective goggles do have particular requirements on frame material that regular plastics are seldom utilized. Compared with regular prescription eyeglasses used in an indoor environment, UV sunglasses also impose their own requirement on this factor. A phenomenon that proves this extra requirement is that metal sunglasses are more popularly seen than plastic sunglasses. There are some brands that exclusively use metal frames in producing sunglasses, such as Ray Ban Aviator.

The superiority of metal frames over plastic frames is rooted that sunglasses usually have large lenses which require a strong frame. Making a comparison between regular metals and plastics, sunwear designers and manufacturers may naturally find that the first group features better strength. This briefly explains that leading role gained by metal sunglasses in the current market. Metals like titanium, beryllium, stainless steel, Flexon and aluminum all have the property of strength, thus being able to hold the large sunglass lenses in place. In contrast, plastics ranging from cellulose acetate, zylonite to propionate can hardly be strong. This is the biggest shortcoming that prevents plastics from being widely applied in the sunwear industry.

Metal sunglasses can benefit from several advanced materials which feature strength and other advantages. Stainless steel is an alloy that is hypoallergenic, lightweight and strong. In particular, this material used in sunglass frames can be corrosion-resistant. This attribute is unparalleled by other materials. Titanium is also a good material for sunwear frames. It has similar features to stainless steel. The popularity of memory metal can not be overstated. In fact, both eyeglass and sunglass frames take use of this new form of metal widely. The extreme flexibility offered by memory metal is incomparable by other metals.

Magnifying glasses for reading aid

August 23rd, 2010 by Jay Furlong No comments »

Among individuals over 40 and 50 years old, it is a common practice to stretch the arm to the limit when they try to read up-close materials. Placing a book, newspaper or menu at a normal distance will only lead to a blurry effect. This is very probably the symptom of presbyopia, an age-related vision problem. Like other groups such as the myopia, the hyperopia and even the astigmatic, patients suffering from presbyopia also need to rely on external help or vision aid. Otherwise normal reading is impossible. The solution to presbyopia through corrective eyewear is usually magnifying glasses. It is not difficult to see a senior reading a newspaper with a pair of glasses. Similar to myopia glasses and hyperopia glasses, magnifying eyeglasses are also magic that they can “bring back” normal, clear vision for presbyopic patients.

It is worth stating that presbyopia is a vision condition essentially different from myopia and hyperopia. While the latter two conditions are caused by abnormalities in eyeball shape and are called refractive errors, presbyopia is closely related with the natural lens’ aging and loss of elasticity. As a result, magnifying glasses function in a considerably different way from nearsighted and farsighted eyeglasses. Another difference between magnifying eyewear and glasses for refractive errors is that the first type can be got without a prescription. Pre-made of pre-fabricated magnifying eyeglasses are widely available over the counter. In the 1990s, ready-made magnifying spectacles became extremely popular that over 30 million pairs were sold. This medical practice is completely different from the purchase or selling of myopia and hyperopia glasses which require strictly a valid prescription.

Magnifying glasses have been highly expanded in form of lens power. The most traditional form is regular reading glasses whose whole lenses are equipped with a reading prescription. They are the first choice for people who spend a great deal of time concentrating on near reading. Multifocal forms of magnifying eyewear are thought to be more powerful because they can deal with several conditions within a single pair. Bifocals, trifocals and progressives are currently available.

Possible benefits of wearing plastic sunglasses

August 22nd, 2010 by William Krause No comments »

Plastic eyewear frames have a traditional negative image in some people’s mind. There are some conventional drawbacks associated with plastic sunglasses and eyeglasses. For example, these frames are more fragile than metal frames under external impact. Even if they are not easily ignited, plastic frames may burn after a long period of sunlight exposure. In addition, long-term sunlight exposure may also lead to a decrease in frame strength. Well, it is possible to point out a couple of other reports on plastic frames’ shortcomings. An opposite side is that metal sunglasses are prevailing. Titanium, stainless steel, aluminum and memory metal have been widely used to make eyeglass and sunglass frames. And it seems that these advanced forms of metals tend to replace gradually those traditional plastics. But the current fact is that plastic frames and metal frames develop generally in parallel.

The current status or proportion maintained by plastic sunglasses in this market is well founded. And most people may suppose that plastic sunwear frames have their own features or advantages. This is the emphasis of this article. It is the plastics’ natural properties that help these materials maintain their popularity in lots of industries including the eyewear industry. The first priority should be given to lightness, which is an attribute claimed by nearly all types of plastics, varying from zyl, cellulose acetate propionate to nylon. This feature or advantage is a common place among all plastics. Sunglasses are usually used in an outdoor environment. Lightness is an important contribution, especially to performance or sports sunglasses. It is true that metals like titanium, beryllium, stainless steel and aluminum also claim lightness. However, they are lightweight only compared with traditional metals like iron, bronze or gold. Plastics are unbeatable in this aspect.

Another point that helps plastics gain the current status in the sunwear industry is their flexibility in color application. Plastic sunglasses can be easily found in various colors like green, orange, red, purple and any other. In contrast, metal sunglasses are generally disappointing in color provisioning. The reason is that plastics are easier to be tinted than metals. In regular, colors are applied to the surface of plastics or metals. Yet most plastics also allow a color mix-up in them.

August 19th, 2010 by Reza Hyver No comments »

In early times, contact lenses can only be worn in the day time and people have to pick them off at night. Later, there are nigh and day contacts sold at the market. People with night and day contacts need not to handle them every day, for these lenses can be worn at night as well. Several decades have passed since the first night and day contacts appeared. And with the development of rapid technologies, great progress has been made in the manufacturing of night and day contacts. Of which, various categories of night and day contacts sold in the market are typical examples. Among all the night and day contacts, CIBA vision night & day are very outstanding.

The year 1980 was very important for CIBA vision night & day. It was the day when Ciba-Geigy began to step into contacts field and CIBA Vision was established. In 1997, the first CIBA vision night & day contacts had been put into market in Mexico. Later, in 1999, CIBA vision night & day were certificated by the EU selling at the European market. The two events had paved the way for the rapid growth of CIBA Vision, which speeded up the steps developing CIBA vision night & day.

Typically, the permission of EU to wear these contacts for 30 days represented that the manufacturing of CIBA vision night & day had stepped into an upsurge stage. The year 2001 was typically remarkable for CIBA Vision, for the CIBA vision night & day had been certificated by FDA.

How can delicate glasses last for a long time?

August 19th, 2010 by Reza Hyver No comments »

Prescription eyeglasses are needed by a large number of people on a daily basis. For this group of patients, a severe vision condition forces them to rely on an Rx eyewear during a majority of daily activities, ranging from reading a newspaper to watching TV. For those who have a long history of eyewear usage, a bothersome problem is that prescription eyeglasses are usually delicate. These delicate glasses are to some extent quite fragile under external impact. As a result, regular eyewear users have to sometimes get their glasses repaired or replaced. Replacing eyewear partially or completely certainly causes much expense. In fact, there are possible ways to minimize the risk of breaking prescription eyeglasses. Due to technological improvements in both lens and frame industries, there have been some solutions that enable eyewear to be much more durable and strong. Resorting to these solutions will generally help protect the eyewear.

The frame is responsible for holding the lenses and it should firstly be durable and impact resistant. Delicate glasses first rely on this protection from the frame. In the current market, eyewear frames made of certain materials have gained significant improvement in durability and impact resistance. Titanium, beta-titanium, stainless steel and memory metal are the best options. All of them are lightweight and impact-resistant. In particular, memory metal still features extreme flexibility, allowing the frame to be bended to a considerable degree. In terms of durability, frames made of these metals are superior to traditional plastic frames. Moreover, some unusual materials like bone and wood can hardly guarantee durability. They only flatter distinctive tastes.

Delicate glasses need safety consideration not only about the frame, but also about the lenses. To a certain degree, the lenses are the major part that is exposed directly to external impact. This makes the selection of impact-resistant and shatter-resistant lenses a necessity. Traditionally used materials like glass and regular plastics are too delicate to withstand a flying object like a tiny stone or a pen. These inferior materials have largely been abandoned. Instead, new materials like high index plastics and polycarbonate are on the rise, because of their valuable features including impact-resistance.

Possible parts of a pair of complete eyeglasses

August 18th, 2010 by Charles Garrana No comments »

Eyeglasses may be used to gain vision correction, UV protection or injury prevention. Modern eyewear products are generally similar in the overall structure, regardless of those slight differences or variations. Most people know that a pair of complete eyeglasses consists of two lenses and a frame. Well, this is absolutely true that the frame aims to hold the lenses in place and the lenses will provide related visual help. These two parts are mutual complementary and form the basic structure of an eyewear. This classification of different roles is reasonable but some details are shielded. A complete pair of eyeglasses involves many more small parts, which will be discussed in the remainder of this writing.

Eyeglasses lenses can not be further divided that they must be complete should they function properly. But the situation of an eyewear frame is quite different. A pair of complete eyeglasses has a couple of frame parts, each of which serves in a specific way. The frame front refers to the front part of a frame that holds the lenses in place and bridges the top of the nose. In other words, this part includes typically two rings and a bridge. To some extent, this is the most important part of the frame because it connects the two separate lenses via the nose bridge. Moreover, the frame front is sometimes further divided into two eye wires and a bridge. An eye wire is the part into which a lens is inserted. And a bridge is the area between the lenses that goes over the nose and supports 90% of the eyewear weight. There are different types of frame bridge, like keyhole bridge, saddle bridge, adjustable bridge, double bridge and even triple bridge.

In addition to the frame front, there are also two end pieces to which the temples are attached. In some cases, these two end pieces are referred as the extensions of the frame front. Another two tiny parts are hinges, which connect the frame front to the temples and allow the temples to swing. This is the key part that links the frame front with the temples. The bridge mentioned above is not the only part that helps hold the frame. The two temples extending over or behind the ears also take a fraction of the frame weight. Complete eyeglasses also have two nose pads and possibly pad arms, top bar or temple tips.

What are gradient tint sunglasses?

August 17th, 2010 by Edward Turner No comments »

In the market filled with diverse products, it is nearly impossible to find a pair of sunglasses with clear lenses. Almost all sunglasses come with tinted lenses in different ways. That is for sure that UV protection is the key function provided by sunglasses. And in fact the degree of UV protection is determined by the lens material used and some additional lens treatments. Various tints only determine the darkness of the lenses. But this factor does not determine directly the capability of UV protection the lenses have. With this explanation, some people may wonder that why these lens tints are so popularly used, like a rose, a yellow tint, green tints and gradient tint sunglasses. Remember that different tints have specific degrees of darkness, which determine the amount of sunlight that is allowed to pass the lenses.

There are generally two ways to tint sunglass lenses. Some manufacturers add a substance such as metal oxide to the lens material during lens production. The other way is more popular that surface application allows a wide variety of tints and creates different darkness across the lenses. Most sunglass lenses are tinted in the second way, including gradient tint sunglasses. The intensity or darkness of a tint is expressed as a percentage of the light that is allowed to reach the eyes. It is well-known that sunglasses are used for different purposes, ranging from pure fashion enjoyment to outdoor sports. A fashion tint usually blocks 10-20% of sunlight. Outdoor activities and daytime driving require related lens tints to have an intensity ranging from 70-80%. 90% tints are suitable for sports like climbing and snow skiing.

Among all types of tinted sunglasses, gradient tint sunglasses are quite special that they have different degrees of darkness from the top to the bottom. Rose tint sunglasses, gray tint sunglasses and some others all use tinted lenses that have a uniform darkness across the entire lens. Dissimilarly, a gradient tinted lens has a dark tint at the top, and fades gradually to little or no tint at the bottom. This design allows the lens to block more sunlight coming from above, without blocking too much light from straight ahead or below. A variation of this design is double gradient tint lens, which has a darker tint at the top and bottom, and a medium tint in the center part.
