Computer Vision Syndrome (CVS) can cause eye strain, headaches, and blurred vision. Computer glasses can protect against CVS, while also blocking UV rays and reducing glare. Optometrists offer computer-specific tests to optimize computer vision, and glasses can be polarized and filtered to make computer time healthier. Photochromic lenses can double as sunglasses, and all eyewear must be free from defects.
Today more than ever they work on the computer. Staring at a flat screen for hours can cause eye strain, headaches, dry eyes, burning eyes and blurred vision, known as Computer Vision Syndrome (CVS). Computer glasses can protect you from CVS by improving your vision with or without a prescription. They can also block harmful ultraviolet (UV) rays and reduce glare, both of which are linked to cataracts.
For those who wear contact lenses or corrective glasses, one complication of spending long hours at a computer is that the average distance from a computer screen is farther than reading material, but closer than distance viewing. Bifocals used for reading are not optimized for computer work, and while reading material is held on your lap, a computer screen sits in front of you. This forces bifocal wearers to tilt their heads up, which can create neck and shoulder strain. It might also make one lean towards the screen to reduce the distance from the range that bifocals are designed to correct.
Because of the unique needs of computer users, many optometrists today offer computer-specific tests to optimize computer vision. Glasses optimized for computer use can be polarized to reduce glare and filtered to block UV radiation. All of these factors translate into computer glasses that are designed to make computer time more enjoyable and healthier for your eyes.
For those who lack correct vision but experience symptoms of CVS, computer glasses can relieve CVS by enlarging the screen to reduce eye strain. Plain pharmacy reading glasses are intended for reading close-up material and may not be suitable. An optometrist who offers a machine vision test can tell you if you will benefit from eyeglass correction.
If you don’t spend enough hours in front of a computer screen to experience CVS, but you want to protect your eyes from glare and harmful radiation, high-quality non-prescription glasses with polarized lenses and UV blocking will serve as excellent computer glasses. You can have a pair made by an optometrist, or you can opt to purchase lightly tinted, optically correct, polarized sunglasses with 100% UV blocking. High quality sunglasses are available in most sporting goods stores, usually kept in display cases.
If you want computer glasses that can double as sunglasses, consider photochromic lenses. These lenses lighten indoors and darken outdoors. Polarized photochromic sunglasses can serve as flexible and convenient computer sunglasses. Photochromic lenses are also available by prescription.
All eyewear must be free from defects. If you hold your glasses at arm’s length and look through the lenses, they shouldn’t wobble or distort what’s behind them. Lenses are available in lightweight polycarbonate, or for those with heavy prescriptions, high-index plastic. See your optometrist for a computer test to ascertain the best prescription and get rid of eye strain.
