Blue light glasses
Are eyeglasses with special blue light-blocking filters worth the expense? By absorbing the excess blue light from our devices, the eyeglasses claim to:
- improve sleep
- reduce digital eye strain
- and prevent eye disease
We all want to do these things, but it’s not necessary to spend money on special eye wear for computer use. Here’s why:
- Blue light from computers will not lead to eye disease. It is true that overexposure to blue light and UV light rays from the sun can raise the risk of eye disease, but the small amount of blue light coming from computer screens has never been shown to cause any harm to our eyes.
- Sleep can be improved without special eyeglasses. You don’t need to spend extra money on blue light glasses to improve sleep— simply decrease evening screen time and set devices to night mode.
- Digital eye strain is not caused by blue light. The symptoms of digital eye strain are linked to how we use our digital devices, not the blue light coming out of them.
