Ophthalmic
In general, sunglass lenses are used to protect the human eye against excessive solar radiation, to reduce eye strain and to increase the visual comfort.
In order to secure fatigue-free vision, even for prolongated usage, the choice of filter depends on the ambient light level and the individual sensitivity to glare.
The European standards DIN EN 1836 + DIN EN 172 specifies the properties and the recommended application of sun glare filters.
The sun glare filters for general use are classified into 5 filtering groups, and the admissible transmittances in the UV region, the visible region and the IR region are clearly specified.
SCHOTT Ophthalmic offers:
- lens blanks with UV and IR protection
