Re: Monitors

The 20-20-20 Rule
When people are doing near vision tasks, such as looking at a monitor, they tend to blink less often. This can result in decreased tear production which leads to dryness of the cornea. A dry cornea will result in blurred vision and irritation of the eyes. To prevent this, follow the 20-20-20 rule. Every 20 minutes, take an eye break and look 20 feet away for 20 seconds. This will give you a chance to blink and produce some tears and will give your eye muscles a chance to relax.
