How Screen Time Affects Your Eye Health

How Screen Time Affects Your Eye Health

The more time people spend on their digital devices, the greater their chances of developing eye problems that can affect their vision. Too much screen time can cause digital eye strain, eye dryness, irritation, and fatigue, all of which can adversely affect your vision. If you’re having problems with your eyes, consult with your Sammamish optometrist from NewVision Eyecare. We can provide valuable insight on how to counter the effects of digital eye strain to protect your vision.

Here are some of the ill effects too much screen time can have on your eyes.

Dry Eye

Blinking helps produce tears to lubricate your eyes. When you use your cell phone, computer or tablet, you don’t blink as much as you should. This causes your eyes to become dry and irritated, aka dry eye. The more time you spend on your digital device, the worse your dry eye condition can become. Dry eyes can cause such symptoms as burning, itchy eyes, redness, soreness and blurred vision. By taking breaks from your device regularly, you can avoid dry eye syndrome.

Eye Strains

Staring at a digital device for prolonged periods of time put your eyes under enormous strain. Eye strain can cause blurred vision, double vision, headaches, and sensitivity to light. To counter the effects of eye strain, you can put the 20-20-20 rule into effect:  For every 20 minutes that you spend on your digital device, look away at something 20 feet away (or further) for at least 20 seconds. This alleviates eye strain by allowing your eyes to rest.  


Computers, cell phones, tablets and other digital screens emit high energy light wavelengths commonly known as “blue light.” Blue light is known to suppress the effects of melatonin, a hormone in your system that helps you sleep. Using your devices at night can make it difficult for you to fall asleep.

Consult with Your Optometrist

By using your devices wisely, you can avoid eye problems that hurt your vision. To learn more about protecting your eye health, call NewVision Eyecare in Sammamish at 425-392-2196 today.
