The need for computer glasses has become increasingly important in recent years, due to the numbers of people who sit in front of computers for many hours at a time. It is not uncommon for such folks to experience eyestrain occurs from intense use at the computer, blurred vision, dry eyes, red eyes, headaches, sore neck, sore back, shoulder pain, increased sensitivity to light, difficulty focusing, and other symptoms of what is increasingly referred to as computer vision syndrome. Unlike the visual demands associated with most other activities, computer work often involves the eyes changing focus from the keyboard to the screen and back again. You may not be able to change the nature of your job or all the factors that can cause eyestrain, but there are steps that can be taken to reduce eyestrain including buying a pair of computer eyeglasses at Eyeglasses.com.
The onset of presbyopia, a normal age-related loss of the ability to easily focus up close for folks fifty years or older, eye muscle imbalance, or uncorrected vision can compounded computer vision issues. If you find yourself tipping your head to look through the bottom portion of bi focal glasses or often leaning forward or back to see words on your computer screen, or experiencing some computer vision syndrome symptoms, it is time, most likely, to consider getting computer glasses. Handy computer glasses really should not be considered just another type of reading glasses eyewear, nor called “computer reading” glasses.” At Eyeglasses.com we offer a number of computer eyewear frames that will accommodate computer distance prescriptions making your days at the computer more comfortable.
There is some confusion over what computer glasses actually are. Basically, computer glasses are simply prescription eyeglasses that are made with a focal distance for the computer. In the language of optician-speak, this is known as the "mid-range," the range between regular reading distance and long vision distance.
Computer glasses are designed to optimize the mid-distance to the computer screen. Computer glasses differ from regular eyeglasses or reading glasses, because computer screens are usually positioned 20” - 26” from the user's eyes. You simply cannot use glasses that have prescriptions for either distance or close up vision needs. You need computer glasses that are made with large intermediate distance zone lenses. Peruse the Eyeglasses.com selection of computer eyeglass frames to find the frames you want.
Computer glasses are now becoming available with more complicated, occupational bifocal lenses (two viewing areas with a visible line between them), trifocal lenses, and progressive lenses (a bifocal without the visible line). These new computer glasses lenses tend to have a larger intermediate distance zone area suitable for viewing content on the computer screen. Before going to an eye doctor for a prescription for computer glasses, sit at your computer and have someone carefully measure the distance between your eyes and the computer screen. Your eye doctor can then determine the glasses’ prescription with a focal distance appropriate for computer work. The simplest computer glasses (one viewing area in the lenses), have single vision lenses made specifically with a lens power prescribed to prevent computer eyestrain. These computer glasses would not be suitable for driving or other significant distance vision tasks nor for close up reading needs. Once you have your prescription and your PD distance, which you should ask for during your eye exam, you are ready to select computer glasses frames at Eyeglasses.com.
The research and development of computer eyeglasses lenses has evolved to where lens coatings and tints are becoming more common. Many opticians believe the lenses of computer glasses should include an anti-reflective coating for maximum viewing comfort. Anti-glare or anti-reflective coating has been around for awhile and is recommend for both night driving and reading, as well as for computer glasses. Another coating that is recommended for computer glasses is protection from UVa, UVb, & HEV. The UV-protective treatments for eyeglass lenses block specific rays from damaging the wearer’s eyes. Be aware that all eyeglass lenses from Eyeglasses.com use only Essilor made lenses that which already have 100 percent UV protection built-in, so an extra lens treatment is not required. You may also find some computer glasses that are tinted an unmistakable yellow tint. This memorably colored tint increases the contrast on the screen and filters out the uncomfortable, harsh light spectrums allowing eye muscles to be more relaxed while working at the computer.
