The 20-20-20 Rule
When working on a computer or other digital device, remember the “20 -20 -20” rule: Every 20 minutes that you spend looking at a screen, look at least 20 feet away, for 20 seconds. This helps to give the muscles in the eye that are straining to keep your screen in focus a rest period, and can help to reduce eye strain and headaches. And taking a supplement like TWINLAB OCUGUARD BLUTEIN
PROTECTION with lutein, zeaxanthin, and blueberry extract acts as a nutritional filter against high-energy blue light emitted by cell phones and computer monitors.
