Or, more practically take advice from two eyecare professionals about protecting your eyes whilst at work. Kevin Kretch, a licensed optician and Dr. Giselle Lander, an optometrist give examples of what parts of the office cause strain on the eyes and what we can do to protect our eyes in this environment.
When we wear sunglasses to protect our eyes from sunlight, we are actually protecting them from Ultra Violet (UV) rays. Office lighting is usually fluorescent light which contains both blue and violet rays. These rays are similar to (UV) rays and can harm your eyes over time.
Dr Lander says, “There are a lot of variables, like if (the light) is dark or light… prolonged exposure could cause symptoms of eye fatigue and eye strain.” To avoid eye strain she suggests wearing anti-reflection glasses that can eliminate glare.
Kretch explains that “blue light can cause macular degeneration and the coating (on glasses) can help fight that.
Both Kretch and Lander explain that anti-reflective lenses aren’t just for those that wear prescription glasses, people with good vision need to protect their eyes too and will benefit from the lenses to avoid wearing prescription glasses in the future.
Computer screens are a major factor for office workers. As we are in a digital age, almost all work is completed on computers and for several hours a day. The biggest issue is the amount of time spent looking at computer screens without blinking.
Lander said, “Basically, what the computer can do is fatigue the eyes and dry them out.”
One way to reduce the strain on your eyes is to adjust your screen according to the light in your office. If your office is quite dim, you want to avoid a very bright screen as this contrast of lighting can cause eye fatigue.
Taking breaks from your screen is also very beneficial and using the 20-20-20 rule; every 20 minutes, look away from your screen for 20 seconds while focusing on an object 20 feet away.
Dr Lander also advises to blink a lot “because without blinking, the eyes can be very dry. Dry eyes can cause other problems to arise as well.”
The way you sit and your distance from the screen is also a major factor in protecting your eyes from the computer screen. Lander explains, “You have to be sitting properly and looking down at your computer that should be at least 18 inches away. You should ensure your eyes are at the same level as the top of your screen.
