Are you saying that the tint doesn’t matter?

In terms of UV protection, since ultraviolet radiation is ‘invisible light’, it’s not affected by any ‘visible tint’. That being said, the tint on the lens is important for brightness, glare, and contrast: gray tints block all light equally, while brown lenses preferentially block greens, and rose or amber (‘blue-blockers’) improve contrast by reducing scatter. Polarized lenses block reflected light from flat surfaces including snow and water, making them ideal for skiers and boaters. In short, tints are selected mainly based upon patient preference, while coatings and materials are selected for protection.
