Getting rid of our digital devices is not a realistic option for any of us. However, there are ways one can ward off the damaging effects of blue light.
- TAKE REGULAR BREAKS
Every 20 minutes look away from the screen and focus on an object about 20 feet away for 20 seconds. This will rest your eyes and limit blue light exposure. This is known as the 20-20-20 rule.
- POWER DOWN YOUR DEVICES
Whenever possible power down your devices especially at night. Blue light affects your body's ability to release melatonin, the sleep hormone. Powering down three hours before you go to bed will help protect your eyes and should result in a better night's sleep.
- BLUE LIGHT FILTERING LENSES
Getting lenses that filter blue light and ease digital strain can be of great benefit. One study found that people using blue light filtering lenses had less eye strain, blurred vision and dry eyes after long periods of screen time.
- SCREEN FILTERS
Using a screen filter on your phone, tablet and computer can cut down on the amount of blue light a screen gives off.
- DIET RICH IN LUTEIN & ZEAXANTHIN
Lutein & Zeaxanthin are antioxidants that accumulate in the lens and retina of your eyes. One study showed that people who consumed healthy amounts of these two antioxidants for 6 months straight had less eye strain, headaches, and improved quality of sleep. Diet-related loss of lutein & zeaxanthin enhanced phototoxic damage to the human eye. A diet rich in lutein & zeaxanthin not only protects your eyes but also potentially improves cognitive function in the elderly.
