20 Jan Computer Glasses: Blue Control Explained
What are Computer Glasses?
We regularly have patients at our clinics complaining about eye strain and dry eye. These days, because we spend so much time on digital devices, this is a common problem. In fact, in a survey it was found that over 70% of adults reported having some kind of digital eye strain (strained, dry or red eyes; blurred vision; headaches; back pain; neck pain; or general fatigue) as a result of using digital devices for hours at a time.
If you work in an office job, it´s highly likely that you get that classic mid-afternoon eye strain – that twitch, dry and altogether sore sensation. Perhaps you need computer glasses – these are glasses specifically designed to delay damage to your eyes if you are chained to your computer screen eight plus hours a day.
So how do these computer glasses work?
Blue Control lenses work to filter out blue light. So now I can hear you yelling at your screen:
WHAT IS BLUE LIGHT?
Blue light is the type of light emitted from digital screens, made up of a very short wavelength that produces a high amount of energy. Sunlight is made up of UV and blue light, as part of visible light spectrum, but it’s the blue light that causes the most amount of damage as over-exposure to it can cause long-term problems in your retinas.
Computer glasses filter up to 50% of bad blue light away from your eyes and defect up to 90% of glare – shielding your eyeballs while you work.
But do they actually work?
We have been prescribing Blue Control Lenses for many years. Our patients have said that that when you look through them there aren´t any drastic changes – the screen looks normal, no brighter, no different. However, they have noticed that they suffer less from headaches, experience less eye pain, don´t have the feeling of scratch eyes and were less prone to twitching. Some have commented that they feel that they are sleeping better than before they got the glasses.
Are computer glasses for you?
Whether or not computer glasses will be worth it and work for you is subjective, because factors include your visual abilities and computer usage, work environmental conditions and your viewing habits.
A lot of people who experience digital eye strain often simply ignore it. People are so used to their eyes feeling tired at the end of the day, they just accept it. However, just because it´s normal doesn’t mean it´s ok! Why not talk to us about helping to get those eyes better?
Perhaps a sligh modification to your natural eye strength would drastically improve your on-screen comfort, adding a small prescription can often enhance comfort and productivity at work.
