(76% visible light transmittance = suitable for nighttime use ⇒ darkens to at least 15% under UV light ⇒ UV transmittance of less than 0.01%) The lens of the eye becomes yellow with age. This yellowing reduces the sensitivity to produce the blue light necessary for vivid colors, and instead increases sensitivity to dazzling yellow light.
