The sun emits visible and invisible electromagnetic waves. The most harmful invisible radiation is ultraviolet (UV) rays and they are dangerous even when it is cloudy: clouds absorb only 10% maximum.
Ultraviolet (UV) rays damage the cells of the eye, which translates into pathologies of varying severity. SUN glasses with 100% UV category 3 lenses protect against glare and filter 100% of ultraviolet (UV) rays.
The temples equipped with a spring hinge are flexible and comfortable, adapting to all face shapes and sizes.
This model complies with the European standards for pre-assembled glasses (NF EN 14139) and with the international standards for sun protection glasses (ISO 12312-1).
