When the helmet has no visor, is it advisable to wear safety glasses?

Although not compulsory, safety glasses are also recommended. If the helmet does not incorporate a similar device — a kind of visor that can be lowered at the rider's will — for their own safety and that of others, it is advisable for motorcyclists and moped riders to wear safety glasses that protect their eyes against cold, wind, dust, insects, etc. A simple speck of dust or an insect entering the eye can cause loss of balance and control of the vehicle and be the cause of traffic accidents.
