Blue Light Glasses
Are your eyes tired from looking at a computer screen all day? Some blue-light-blocking glasses might help you alleviate eye strain and help you get a better night’s sleep by blocking out blue light from computer and phone screens. If you have an office or tech job and you spend large amounts of time at a computer, blue light glasses are great to help block out harmful blue light.
Blue light has a short wavelength making it easy for it to penetrate the eyes. This means that almost all visible blue light rays can pass through the cornea and lens to the retina. At the moment, the scientific community hasn’t reached a full conclusion on how blue light affects the eyes since more research needs to be done. However, some experts have suggested that too much exposure to blue light has the potential to damage the light-sensitive cells in the retina.
Blue light glasses are specifically designed to reduce the amount of blue light that reaches the eye. This is done by filtering blue light rays to help prevent them from entering your eye and causing potential damage. Usually, blue light lenses have a slightly yellow tint to counterbalance the blue light, but you are unlikely to notice this.
Blue light blocking glasses are effective at reducing the amount of blue light which enters the eyes, but please understand that there is no current research that definitely proves that this can protect the health of your eyes.
