The science of how they work
There are two points to understand about the working principle of computer glasses:
- They use anti-reflective (AR) coatings on the lenses to reduce screen glare and increase contrast,
- They filter out the harmful blue-violet light emitted by the various devices we stick to. Light in the blue-violet range is called “high energy visible light” (HEV) and is very harmful to the eyes.
The lenses of computer glasses are usually yellow. But, as Eyezen and Zenni demonstrated above, it’s becoming more and more common.
Anti-reflective coatings can also be applied to spectacle lenses. If you think you could benefit from computer glasses, please update your prescription and take the opportunity to buy a new frame!
Should I buy computer glasses?
Take a look at some common symptoms of CVS:
- Dry red eyes
- Plugin the neck and/or back
- Blurred vision
After a day of work, have you noticed these symptoms?
Even if we don’t, we’ll all be spending a lot more time than healthily staring at the screen. After all, we have no choice. Much of our livelihood depends on computers.
Although you don’t experience eye strain, you expose yourself to a brighter blue light than the eyes should take.
Computer glasses are a useful preventive measure. Trust us; you don’t want to have a severe CVS. Not only will it be exhausting, but it will also be everywhere and very painful. Even the simplest forms can distract you unnecessarily and interfere with your work.
Except that an ounce of prevention is worth a pound of treatment, computer glasses have come a long way in terms of style. Although they still offer gaming functions in the yellow version, there are now many glasses that look like regular glasses and do not require a prescription.
We believe that if you buy a pair of computer glasses, you can have the best of both worlds when it comes to protection and fashion.
Do computer glasses work?
When you work on the computer for a certain period every day, for those who play several hours in front of the screen and do so mostly at night, you may experience eye strain, blurred vision, red eyes, and other symptoms of “computer vision syndrome. “or CSV or, in Italian, computer vision syndrome. Indeed, the work that the eyes do when they look at a screen is unlike any other activity.
For those under 40, eye strain or blurred vision may depend on the eyes’ inability to stay focused on the screen or difficulty adjusting the keyboard focus on the screen and vice versa for periods Extended.
These focusing problems are often associated with CVS.
If you are over 40, you may have presbyopia signs, an average loss of focus due to age, causing CVS symptoms.
Also, blue light from screens disrupts biological rhythms and affects the sleep-wake cycle. Disrupt sleep and slow down the production of melatonin in our body.
From this problem, I had done several types of research described in the article on protecting the sight of computer screens and cell phones.
Those who have to work or play at the computer for several hours a day, especially at night, when the first tip is to go to an ophthalmologist, you may want to consider purchasing personalized computer glasses, even graduated ones.
Computer glasses differ from regular glasses or reading glasses because they are designed to optimize your eyesight when looking at the computer screen.
They are designed to reduce glare (the leading cause of eye strain), filter out blue light, increase contrast, and maximize what you see through the lenses, making it easier to view a screen for long periods.
The main characteristics of computer glasses are as follows:
- Anti-reflective (AR) Coating: Eliminates light reflections on the lenses’ front and back surfaces that can cause eye strain.
- Lens coloration: Some computer glasses have a generally yellow color designed to increase the contrast of the screen and filter the spectrum of blue light so that the eyes’ muscles relax.
Other companies leave darker lenses transparent, in some cases perfect as sunglasses, with photochromic protection.
How effective are these computer glasses?
To answer this question, it would certainly be best to contact an ophthalmologist first.
From the information, I found online (e.g., here, here, and here), I realized that the feeling of well-being they provide is purely subjective and depends on other factors, including the quality of the monitor you are looking at, the environmental conditions of the place, the display habits and brightness around.
If you don’t have eyesight problems, it is unnecessary to purchase computer glasses.
After seeing an ophthalmologist, if you have computer vision symptoms, it might be a good idea to buy a pair of these glasses, using the best brands and not saving money.
For my experience, given that I am at the computer several hours a day and suffered a lot from burns and red eyes, I have been using computer glasses for four years with reasonable satisfaction, finding so much relief that I can’t live without them (and maybe that’s not a positive factor).
