If your question relates to sunglasses, then yes! Sunglasses are a great way to protect your eyes from the sun’s harmful blue light rays.

If your question is about prescription glasses with blue light blocking lenses then you’re in luck because I just asked my optician the same thing. He said because the technology is new, there aren’t very many studies to support the idea that some exposure to blue light from electronic devices is long-term harmful to our vision. He said the studies that exist to support the blue light filtering technology are based on unlikely circumstances. For example, rats were exposed to constant, bright, blue light for an extended period of time. Over time, the rats’ vision decreased slightly, leading the studies to conclude that blue light is harmful, but the studies aren’t representative of the amount of blue light most people are currently exposed to on a daily basis.

Overall, he felt that the blue light from the sun is much stronger and more harmful than the blue light from electronic devices. So if you’re really worried about blue light, it’s best to wear sunglasses! Since the science isn’t really available to support blue light filtering for electronic devices, he felt it might be a marketing scheme that feeds on people’s fear of making more money.
