Glasses not only correct vision, but they can also protect against different types of light. One kind of light that can be harmful to eyes is blue light. It is the only type of light that reaches the retina after passing through the cornea and lenses and comes from screens and the sun. Here, learn about eyewear that shields the eyes from blue light to decide if these lenses might be a good choice for you.

Frequently Asked Questions About Blue Light Filtering Glasses

Why is blue light bad for the eyes?

Blue light benefits the body by regulating circadian rhythms, or natural sleep-wake cycles. However, continued exposure to blue light can contribute to eyestrain. While blue light is not considered as dangerous for the eyes as ultraviolet (UV) light, overexposure could increase the risk of age-related macular degeneration (AMD) and cause strain issues. While more research is needed to confirm the link between AMD and blue light, epidemiologic evidence suggests that increased exposure heightens the AMD risk.

What are blue light filtering glasses?

Some glasses filter the blue light from the sun, portable devices, television, and other digital products. By preventing the light from entering the eyes and reaching the retinas, the eyewear can offer benefits such as reduced eye strain and a lower risk of eye diseases. Blue light eyeglasses can also promote healthy sleep habits by preventing circadian rhythm disruptions caused by nighttime exposure.

Who should wear blue light eyewear?

Those who work in front of computer screens every day may benefit from blue light filtering glasses, enjoying perks such as fewer eye strain-related facial pains and headaches. People who work outdoors most or all of the year should also consider eyewear that protects their eyes from excessive blue light and ultraviolet light.

Do blue light lenses require a prescription?

It is possible to order both prescription and non-prescription blue light eyewear. Simply request your prescription with blue light filters if it’s time for new eyeglasses or ask your eye doctor about non-prescription eyewear for activities such as using portable devices at night. Blue light filters can be added to prescription and non-prescription sunglasses in addition to standard corrective features.
