Digital devices such as cellphones, computers and tablets that we use every day emit blue light, which may have adverse effects on your overall health. In this post, your local eye doctor, EyeSite of The Villages, discusses what blue light glasses are and how they can help.

What Are Blue Light Protection Glasses?

Spending too much time in front of a computer or any digital device may result in digital eye strain. Repetitive eye movement when looking at a screen, plus the glare and contrast from the screen, can cause discomfort. 

Some studies suggest that blue light from LED lights can harm the retina and even increase the risk of macular degeneration. Another problem with blue light exposure is negative effects on circadian rhythm or sleep-wake patterns.

Special eyewear can be worn for blue light protection. Blue light lenses filter out blue light and protect the eyes from blue light penetration. You can rely on EyeSite of The Villages for high-quality eyeglasses that suit your needs.

When Blue Light Glasses Are Most Useful

Blue light glasses are beneficial for nighttime use when blue light from digital screens affect your sleep patterns. The body recognizes blue light as daytime, so exposure during the night affects your internal body clock. As a result, it will be harder for you to sleep and you’ll also have difficulty waking up in the morning. 

There’s growing evidence that blocking blue light before going to bed promotes better sleep. In a 2009 study, participants said that they slept better when they wore blue light-blocking eyewear three hours before bed.
