How To Protect Eyes From Computer Screen
Pediatric Eye Clinic
1. Use The 20/20/20 Rule
Your eyes aren’t designed to stare all day at something directly in front of you. With the 20/20/20 rule, you give your eyes a much-needed break during long work days.
If you look at the screen for 20 minutes, you must look at something at least 20 feet away from you for 20 seconds. The longer you look away from your screen, though, the better!
2. Ensure Your Room Is Well Lit
It may sound counterintuitive, but less light in your room is actually better for your eyes when you’re working on a computer. Offices shouldn’t be too bright, so when possible, close your curtains and reduce your use of fluorescent lighting.
Use lower voltage bulbs and make sure your ambient lighting is about half as bright as the average office.
3. Have Regular Eye Exams
Regular eye exams help to keep your eye health in check and ensure any problems you might be having aren’t anything other than normal eye strain. It also provides you an excellent opportunity to talk to an expert about your habits and eye health!
4. Reduce Glare
Glare on your computer screen can cause eye strain as it stops your eyes adjusting as easily as they should to the content you’re trying to focus on.
Use an anti-glare matte screen where possible (rather than glass-covered LCDs). If you’re a glasses wearer, make sure your lenses have an anti-reflective coating.
5. Use High-Resolution Screens
Most people don’t have to use CRT screens any more. Those are the old computer screens with low refresh rates that created a noticeable flicker that made your eyes feel uncomfortable.
Today, screens typically offer refresh rates of 75Hz or more. The higher the better. Furthermore, screens with higher resolutions appear more lifelike. When you can’t see the pixels, your eyes don’t work as hard to make sense of the images in front of you.
6. Reduce Blue Light
Blue light has a short wave-length and is known for causing damage to the eye. Reduce blue light by using specialist glasses or reduce the color temperature of your screen. It’s ideal for long-term use.
