For your eyes to remain fully operational as long as possible you need to look away from the screen at intervals. This is to allow the eye ciliary muscle to relax. You can relax your ciliary muscles yourself without this tool, just follow the 20-20-20-20 guideline. Every 20 minutes of screen time look at an object at least 20 feet away for 20 seconds.
