Wiley X lenses must also pass ANSI optical clarity standards. All Wiley X lenses block 100% of the sun’s harmful UVA and UVB rays (up to 400 nanometers).

Resolving Power

RESOLVING POWER (CLARITY)

Ordinary lenses can distort objects viewed from a distance. As measured in tests utilizing the NBS Pattern 20, Wiley X lenses provide a clear view.

 
Refractive Power

REFRACTIVE POWER

Inferior lenses can alter the true size of objects, as if looking through another person’s prescription lens. Wiley X ANSI rated lenses maintain true relative object size.

 
prismatic power

PRISMATIC POWER

It is common for ordinary lenses to bend light, causing focal objects to appear off center. Wiley X ANSI rated lenses provide a true spatial relationship of objects in the field of view.
