A clear ultraviolet filter can be added to basic plastic lenses. This acts like sunscreen for your eyes.

Antirefective or antiglare treatments are much different today than even a few years ago. They are very easy to clean; repel dirt, water and oil and offer superior scratch resistance. It is not really a coating, as in many cases it is actually bonded to the lens at the molecular level and cannot peel off. AR, as it called, reduces haloes around lights at night; glare from headlights, computer screens and flourescent lights; and increases the amount of light available to your eye under all conditions. Super hard scratch protection is included with a two year protective warranty. A UV filter completes the treatment. Crizal Avance is the antireflective treatment of choice at Rocky Mountain Eye Center. Endura EZ is offered as a low cost alternative.

Colorful mirror coatings are available for sunglasses. Silver and gold are the most popular, but black, red, blue and others are available also.
