RELATED: What your eyes say about your health "Since patients oftentimes require multiple treatments and overexposure to this, light can be potentially dangerous to your vision," she continued.
Examples of risks requiring eye protection can include: impact from particles or debris, light or radiation, wind blast, heat, sea spray or impact from some type of ball or puck used in sports. Eye protection are typically separated into categories based on the style of eye wear and the hazard they are designed to reduce.
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Many blind people wear nearly opaque glasses to hide their eyes for cosmetic reasons. Many people with light sensitivity conditions wear sunglasses or other tinted glasses to make the light more tolerable. Sunglasses may also have corrective lenses, which requires a prescription.

The various cone cells are maximally sensitive to either short wavelengths (blue light), medium wavelengths (green light), or long wavelengths (red light). Rod photoreceptors only contain one type of photopigment, rhodopsin, which has a peak sensitivity at a wavelength of approximately 500 nanometers which corresponds to blue-green light. [ 6 ]
Blue light harms our vision by damaging the eye's retina. The study found blue light turns a molecule in the eye into a cell-killing poison. It kills photoreceptor cells, which do not regenerate.
