You may have heard of blue light and its impact on your vision, especially now that technology has such a prominent role in day-to-day life. Blue light is all around you and actually offers some benefits, such as making you feel alert and awake. However, it can also have detrimental effects on the health of your eyes when overexposure is an issue. While an eye doctor can help safeguard your vision, it's also helpful to learn what steps you can take on your own.

What Is Blue Light?

All light has different wavelengths, with some being longer and less energetic than others. Blue light has a longer wavelength, but it also generates more energy than red, which is at the opposite end of the spectrum. 

It's present in sunlight, but LEDs and fluorescent lights also generate it. This means you're exposed to blue light when watching TV, working on a computer, or staring at a mobile device. In today's computer-oriented world, blue light exposure is more prevalent than ever.

What Impact Does It Have on Your Vision?

Digital eye strain often results from extended blue light exposure. This can cause headaches, dryness, redness, irritation, and problems with focusing. There are also concerns that blue light may contribute to serious eye conditions by damaging cells within the retina. While further research is needed to determine the exact impact blue light has on long-term eye health, the short-term effects are reason enough to recommend caution.

What Can You Do to Prevent Issues?

Limiting screen time is the first step to eliminating eye strain. If you work at a computer for many hours a day, try the 20/20/20 technique. Every 20 minutes, take a 20-second break and focus your eyes on something 20 feet away. This allows the eyes to refresh and refocus.

You can also limit how much digital exposure you receive after work by cutting back on mobile devices and TV viewing. If you wear glasses, visit your eye doctor on a regular basis to ensure your prescription is up to date. The right prescription prevents squinting, which contributes to strain. You can also inquire about moisturizing eye drops if you struggle with dry eyes.
