When your doing sports, working on your yard or handling motorized tools, always wear protection or security glasses!
Security glasses have heat-tempered glass or polycarbonate that are impact resistant and are stronger than normal lenses. They can be done both with and without prescription.
The safety frames are also more robust than ophthalmic ones. They can protect you in many situations not necessarily seen as dangerous.
With only two eyes, we suggest taking care and protecting them.
