Many people spend their workdays in front of a computer. Headaches, dry eyes, and other problems often develop in the form of computer vision syndrome. This issue—which relates to blue light—can have several immediate and long-term effects. Below, you’ll find a full breakdown on this issue and eye care practices you can use to preserve your vision.

Your Guide to Computer Vision Syndrome

What Is It?

Computer vision syndrome, also called digital eye strain, occurs when you stare at a screen for too long. The negative impact is caused by blue light exposure, which occurs naturally in sunlight. It can also be manufactured by LED screens and bulbs. In small amounts, it poses no risk; however, with long-term exposure, you may damage your eyes.

What Are the Dangers?

Blue light has a shorter wavelength than other colors. Because of this, it flickers quickly, which can interfere with visual clarity, create headaches, and potentially contribute to eye diseases like macular degeneration. Blue light also regulates your sleep cycle. When your body senses the blue light in the sky, it knows to be awake. Once the sun sets, it knows to go to sleep. Using a computer at night tricks your body and can lead to poor sleep and insomnia.

How Can I Protect Myself?

If you work at a computer all day, there are a few eye care habits to adopt. Try to take regular breaks; looking away from your screen for 20 seconds every 20 minutes is usually enough. If your eyes feel dry, use eye drops to lubricate them. Blue-filtering glasses may also lessen headaches and eye strain, and should be purchased from an eye care professional. At night, avoid using a computer or other LED screens 2-3 hours before bed so you don’t disrupt your circadian rhythm. If you’re already dealing with computer vision syndrome, schedule an exam with your eye doctor.
