Glasses for computer work the principle of operation, photos, videos
At a constant work at a computer, the human eye is affected by multiple hazards, it is intense visual function at the same distance and the radiation that comes from even the most modern screens. So most people who are forced to constantly use the PC in the near future face the risk of visual impairment. This can manifest itself myopia, decreased visual acuity, cataracts, glaucoma and even retinal degeneration.
Many have noticed that in everyday presence in front of the monitor eyes quickly get tired, worried dry eye, headache, redness, tearing, pain and fatigue. To avoid such symptoms and further deterioration of vision was created special glasses for working at the computer, whose operation helps to prevent unwanted consequences. They reduce the impact of radiation on the visual organ, thereby protecting it.
The principle of operation of glasses for computer
All whose profession is associated with the computer interested in protecting the eye. But many doubt the usefulness of special glasses. To leave such doubts, you just need to learn and understand how to operate glasses for the computer.
The secret is in the lenses: they make special vacuum deposition using the multilayer interference filters. They operate on the principle of screening, passing only safe part of the spectrum. The part that has the radiation in the form of glare and adversely affects the person coverage holds. It is clear that ordinary glasses for vision correction do not give such protection and cannot be used as a «computer».
In addition, coated lenses provide unloading of the visual organs and increase their efficiency. This gives you the opportunity to recover the functionality of the organs of vision. If the vision is normal, use non-optical options, and a degraded view of the selected options with diopters. Then these glasses perform corrective, and protective functions. No lenses can these glasses be used when you are using contact lenses for vision correction.

- the lens and the retina is protected from ultraviolet rays;
- lenses have a preventive effect of some serious diseases and myopia;
- reduced the phenomenon of photokeratitis due to the removal of glare from the monitor.
