It works as a Venetian blind made of iodine crystals in parallel rows that permit only light directly reflected from a surface to pass through, blocking all the array of light waves reflecting from reflective surfaces (such as water, snow, & the road). This lens provides sharper vision, more vivid color reproduction, & improved depth perception. Virtually 100% of UVA & UVB rays are blocked.
