    Yes, blue light can cause damages to retina in eyes as well as lens. Many people know that UV ray is hazardous to eye health. It might lead to cataract or retinal degeneration. Up to recent decades, people found out the blue light, whose wavelength ranges from 500nm to 381nm, is very dangerous too. It is defined as near UV. The melanin pigment in retinal pigment epithelium absorbs the blue light strongly and lead to oxidative damages to the retinal pigment epithelium cells. Lens also absorbs UV and blue light as a shield for the retina, which might result in cataractous lens. To prevent damages from blue light, you should reduce exposure to the blue light. Find some other light source to replace any of the following: cool white fluorescent tubes, full-spectrum lights, daylight tubes or bulbs. Wear eyeglasses or sunglasses is necessary if you need to expose the the UV or near UV. Have a healthy diet rich in vitamin A, lutein, beta carotene, xeaxanthin and anti-oxidants. Vegetables and fruits are good for health which should be taken regularly.

    You could just wear the sunglasses with good uv rays to protect your eyes from the blue light. You should choose the good type of the sunglasses from the real store. The quality there should be perfect. You may also go to the online stores to have a look. But you need to judge its realness.
