Black glasses in the past and today

October 13th, 2009 by Andrew Rabinowitz No comments »

Black glasses are among the most popular and widely choosen. When you wander in retail eyeglasses shops or browse on the websites, you will find that black eyewear is the majority.

During the initial stage of eyeglasses development, there were no colorful eyeglasses, only black glasses were available. Though eyeglasses are provided in all basic colors and even compound colors today, black eyewear was the single choice in those days. The small market may be one reason. In those days, few people bought eyeglasses. Black glasses were generally formal and universal. Both male and female can accept black eyewear. Another reason may be the materials. The colorful materials of both frames and lens coatings that are widely used today are mostly artificially composed. These colorful artificial materials require modern technologies and skills. However, these technologies were not available in those early days of eyeglasses. Black glasses only needed simple techniques so that it was not surprising that black eyewear played a major role.

Currently, black glasses are also competitive. People can easily find eyeglasses in all colors, such as green, blue, red, creamy etc… Some of them are also combined to create special vision effects. These colorful eyeglasses do have seized certain proportion of the market, because they flatter the particular needs of a certain group of people. However, black glasses still remain as the major role. Black eyewear can meet the most tastes of ordinary people. And people need black glasses under most formal circumstances. Black eyewear will hardly bring you unpleasant appearance. Nowadays, nearly all of the eyeglasses brands provide black glasses.

Task-specific computer glasses

October 13th, 2009 by Charles Garrana No comments »

For those spend a significant amount of time each day working at a computer, computer glasses are needed. Computer glasses are special prescription glasses designed for computer screen reading. The computer screen is usually farther away than reading material is normally held so that your regular reading glasses are not suitable for computer work. The distance between your eyes and the computer screen is considered as the intermediate zone of vision. So the professional computer glasses are the right solution. Like piano glasses and shooting glasses, computer glasses are called task-specific glasses since they are created to meet the visual needs of special activities.

Computer glasses are capable of lessening the symptoms associated with computer vision syndrome (CVS). After prolonged computer work, the eyes and the brain react differently to words on the screen and to printed text. Then, CVS is caused. Symptoms often include eyestrain, dry eyes, headache and blurred vision. Accurately prescribed computer glasses will help relieve symptoms caused by CVS.

Before seeing your doctor for a pair of computer glasses, it is recommended to measure your exact work space, including the distance between your monitor and your eyes. This is essential to get the exact prescription of your computer glasses. Sometimes, anti-glare coatings may be added to the lenses of computer glasses in order to reduce the amount of glare from the computer screen.

Computer glasses have several types if equipped with different lenses. The simplest one is the single vision computer glasses, which provide the largest field of computer viewing. Flat-top bifocal computer glasses have a top part for computer vision and a bottom segment for closer reading. Variable focus computer glasses are much like progressive glasses.

Clip ons provide the most convenience. If you wear correction glasses, you can just buy a pair of clip on glasses for other purpose. They eliminate the necessity of buying another complete pair of glasses so that save you money. Clip ons come in different uses.

Polarized clip on shades

October 11th, 2009 by William Krause No comments »

Clip on shades are special sunglasses that without temples. But most of the lenses technologies are applied to them. One of the most common technologies is polarization. So that polarized clip on is created. Tinted lenses reduce the amount of light and darken your vision, but do not solve the glare problem. Polarized clip on shades are the proper solution. Polarized clip on can block reflection of light on smooth surfaces, especially the shining ones. More accurately, polarized clip on shades block 99% horizontal glare and 100% of harmful UV rays. As a result, you will rarely suffer from blurring and vision discomfort as well as eye fatigue.

The lenses of polarized clip on shades are usually made of polycarbonate since clip ons should not impose obvious height to the regular glasses. Due to its lightness, this polarized clip on reduces pressure on the wear’s face and stays comfortably in place. Polarized polycarbonate clip on shades are 10 times more resistant than other glasses so that they are more suitable for sports. Furthermore, polycarbonate polarized clip on reduces the intensity of sunlight to more comfortable level, in order to ease eyestrain, fatigue and headache.

Polarized clip on shades come in various colors. Yellow polarized clip on provides excellent depth perception and contrast in overcast days. This type also gives a sensation of heightened visual acuity in low light conditions. Copper polarized clip on is made of very contrast lenses that are soothing to eyes. It absorbs blue light. The most color-neutral ones are grey clip on shades. They transmit colors evenly and make you comfort in bright and medium light. Brown clip on shades are also gaining popularity. They preserve depth perception for activities such as driving, fishing and golf.

1800 Contacts and eye care doctors

October 10th, 2009 by Angela Garrana No comments »

1800 Contacts, as the world’s largest virtual market of contact lenses, offers a cheap and easy way of buying lenses through its call center and website. Thanks to the contact lenses’ features of being standardized product (most of the contact lenses can be prefabricated, while few needs custom made for special prescriptions), consumers quickly accepted 1800 Contacts as an alternate way of buying lenses. From the government level, a federal legislation, the Fairness of Contact Lenses Consumers Act, was enacted a couple of years ago. This Act requires the doctor must provide the patients a copy of the contact lens prescription after finishing the eye exam and contact lens fitting. This law fully enhances the patients’ benefits of choosing their own place to buy the contact lenses.

1800 Contacts fully understands its subtle relations with the doctors, meanwhile 1800 Contacts also is aware of the significance of doctors’ role in the whole operating of 1800 Contacts. In other words, 1800 Contacts will have no business without the cooperation from doctors. For this reason 1800 Contacts tries very best to respect the doctors and their patients. Under present situation, doctors are almost forced to work with 1800 Contacts, as the competition between eye care professionals and 1800 Contacts physically exists. In front of own interests and benefits, the situation becomes awkward.

But things can’t be reversed. As long as the existence of 1800 Contacts greatly benefits the consuming public, it will for sure grow and boom. Some experts predict that soon a kind of independent third party contact lens fitting lab will provide prescription and fitting service ONLY without selling contact lenses itself.
