Sight20 vs SmilingEyes Go

Staring at screens all day causing tired, dry eyes and headaches? Sight20 helps you protect your eyesight and relieve digital eye strain using the proven 20-20-20 rule. THE 20-20-20 RULE Recommended by optometrists and eye health professionals worldwide: Every 20 minutes spent looking at a screen, look at an object at least 20 feet (6 meters) away for 20 seconds.
