What are computer glasses, and what do they do?
Computer glasses are eyeglasses mainly designed for viewing computer systems, tablets and smart phones. Computer glasses are intended for close-up obligations simplest. They need to now not be worn for using or preferred motive use.
Computer glasses relieve focusing stress from pc use which could cause virtual eye stress. Some laptop glasses also protect your eyes from blue mild emitted by the displays of virtual devices.
Why do you need to use computer glasses?
It’s not unusual to enjoy signs and signs of digital eye stress when viewing displays for prolonged intervals of time. These encompass:
Digital eye strain is likewise called laptop vision syndrome.
Our eyes (and our bodies) aren’t made for observing a near object — like a glowing laptop screen — for long intervals of time. This reasons strain and fatigue of the ciliary muscle inside the eye that controls the form of lens and the focusing electricity of the eye. It also tires the extraocular muscles surrounding our eyes that manage eye role and alignment. The tiring of these muscle tissues results in discomfort and visual signs and symptoms.
Wearing pc glasses can lessen the danger of eye muscle fatigue and discomfort due to extended display screen time.
Some pc glasses also defend your eyes from probably harmful blue light emitted by way of virtual gadgets. More studies is needed to decide if long-term exposure to blue light from digital devices will increase the threat of macular degeneration or different eye problems later in existence. But laboratory research have proven that blue light can damage cells in the retina which can be important for sight.
How to Use Computer Glasses
Basically, computer glasses reduce how a lot focusing your eyes should do while viewing digital gadgets. This is reassuring for people of all ages. It’s in particular helpful in case you’re over age 40. This is while we begin to revel in signs of presbyopia — the ordinary age-associated loss of close to focusing potential.
Computer glasses need to additionally accurate any nearsightedness, farsightedness or astigmatism you’ve got. Research shows that even small amounts of uncorrected refractive mistakes can motive computer imaginative and prescient problems and decreased productivity.

Reading glasses vs. computer glasses
Computer glasses differ from regular eyeglasses or reading glasses in a number of ways.
For greatest comfort, your computer screen and digital devices should be about 20 to 26 inches from your eyes. This is considered the intermediate zone of vision — closer than driving (“distance”) vision, but farther away than reading (“near”) vision.
If you are under age 40 and wear prescription eyeglasses, these glasses will provide clear vision at all viewing distances. But focusing on intermediate and near objects still requires effort by the ciliary muscle in your eye. The longer you stare at your computer and phone screens, the more fatigued this muscle and your eyes become.
If you are beginning to experience presbyopia, bifocals can provide clear distance and near vision. But intermediate vision (needed for computer use and seeing your smartphone) often remains a problem. Progressive lenses and trifocals offer some help for intermediate vision. But they often don’t have a large enough intermediate zone for comfortable computer work.
For these reasons, many people try reading glasses for computer use. But these, too, have limitations.
Generally, computer glasses have about 60% the magnifying power of reading glasses. (The optimal magnification depends on how far you prefer to sit from your computer screen and how close you hold your digital devices.)
Store-bought reading glasses are simply magnifying lenses in a frame.
Good computer glasses, on the other hand, do three things:
1. Correct any refractive errors you have
2. Provide the optimum amount of magnification for viewing your digital devices
3. Protect your eyes from blue light
Also, custom computer glasses position the optical center of the lenses directly in front of your pupils when using your devices. This intermediate pupillary distance is not customized in store-bought reading glasses.
And store-bought reading glasses typically provide little or no protection from blue light.
Custom computer glasses provide a wide, clear view of your digital devices, reduce focusing effort, and offer the added benefit of blue light protection. Lens designs for computer glasses
There are several types of eyeglass lens designs for computer glasses. Because these lenses are prescribed specifically for computer use, they are not suitable for driving or general purpose wear.
Uni-focal computer glasses
The only pc glasses have lenses with the same power throughout the complete lens. These are known as single vision lenses. This lens energy is custom designed on your unique wishes and favored pc viewing distance.
Single vision laptop glasses lessen the chance of eye stress, blurred imaginative and prescient and unnatural posture that may reason neck and back pain. They are cushty for younger and older pc customers alike.
Varilux computer glasses
Progressive pc lenses aren’t any-line multifocal lenses. They have different powers for your distant, intermediate and near imaginative and prescient needs.
Progressive laptop lenses have a bigger intermediate sector than normal revolutionary lenses. This provides a much broader view of your pc display. But those lenses have a smaller area for distance vision and consequently are not recommended for riding.
Bifocal and trifocal computer glasses
Other lenses used for pc glasses include occupational bifocal and trifocal lenses. These multifocal lenses have large zones for intermediate and close to vision than regular bifocals and trifocals. Also, the location of the intermediate and close to zones of those glasses may be custom designed for computer use.
Your optometrist or ophthalmologist can help you make a decision which lens design will high-quality healthy your wishes for laptop glasses.
Tints and coatings for lenses
For greatest consolation, the lenses of your laptop glasses need to include anti-reflective coating. Reflections from the front and back surfaces of eyeglass lenses can purpose eye pressure. Anti-reflective (AR) coating gets rid of these traumatic reflections.
A blue mild filter is another essential to protect your eyes from potentially dangerous high-strength blue mild emitted via virtual gadgets. Eyezen lenses are instance of high excellent lenses with integrated blue mild filtration for pc glasses.
Your eye physician can also endorse including a slight tint to the lenses of your pc glasses to reduce glare from overhead lighting.
Where can I purchase computer glasses?
Resist the temptation to buy reasonably-priced, over the counter studying glasses for laptop use.
Start by using having a complete eye examination to rule out vision troubles or replace your eyeglasses prescription.
Before scheduling your eye examination, measure how a ways you like to sit down out of your pc. Measure from the bridge of your nose to the floor of your pc display screen.
Bring this measurement with you in your eye examination. It will help your eye physician decide the high-quality lens strength for your pc glasses.
