Anti-reflective lenses can reduce eyestrain caused from glare, reflections, and the “halos” you see around lights at night. It helps protect your lenses from scratches and smudges, and can repel dust and water. This coating makes your vision sharper and your eyes appear clearer behind your lenses. Some anti-reflective coatings reduce the amount of reflected UV from the back of your lenses, providing the best overall UV protection possible. They are particularly suitable for water and snow sports because they prevent the reflection of bright light from these surfaces into the eyes.
While making your sunglass choice take into consideration the type of lens your eye needs for maximum protection. It’s important to purchase sunglasses that completely cover your eyes to prevent entry of UV rays from areas which are partially covered. Additionally, sunglasses that are labelled ‘UV 400 ‘ will blocks all light rays with wavelengths up to 400 nanometers. As you make your sunglass choice this season, make sure to consider the most effective lens for your eye needs.
