The U.S. National Safety Council says you should always wear eye protection when you are:

• Working with or around any type of chemical.
• Using tools to make repairs around the home.
• Playing any sport that involves a ball or other object that could strike your eye.

Of all the injuries from fireworks, 16.7% seen at major eye units were serious and were caused by rockets or exploding fireworks (P less than 0.001). Only 53% of all injuries and 12.5% of serious injuries involved children, and in contrast to the 1950s and early 1960s, young adults appear at greatest risk in the 1980s. Legislation to reduce ocular morbidity should concentrate on restricting the use of rockets and exploding fireworks and encouraging the use of suitable eye protection.A laser safety glass is attempting to filter out the wavelength or wavelengths used by the laser, while at the same time attempting to maximize the Visible Light Transmission (VLT). In order to filter out the undesirable wavelengths, special chemical additives are added to the Polycarbonate during the filter (lens) molding process. Ideally the filter lens would filter out the undesirable wavelengths, while leaving the lens clear for maximum visibility (High VLT). Unfortunately, in reality many laser filter lenses have less than perfect VLT and often add a coloration that affects our ability to see all colors clearly and correctly.
