What is Adaptive Lens?
Adaptive( or Responsive) lenses are lenses that react to UV light.
Why do we love it?
Adaptive lenses minimize the cost of having to purchase two different pieces of eyewear since you get the benefit of eyeglasses and sunglasses in one. The lens tint is available in a variety of colors to match your personal style. These lenses are great for people who are always on the move, going from indoors to outdoors several times a day.
How to choose the right lenses
Your lens index. The lens “index” is short for the lens’s “index of refraction.” That means how much the lens bends the light that enters it. That’s what refraction is. Bending the light focuses it right into the middle of your visual sweet spot, the retina, so you can see well.
You can change the index to thin the lens, up to a point. After that point, the law of diminishing returns kicks in. The lens that is recommended for your prescription will be the thinnest lens. Choosing a lens index that’s higher than the recommended lens index won’t make the lens thinner, and you’ll end up paying more for no improved result.
This handy online tool is the Lens Thickness Calculator. It can be found here, at the OptiCampus website.
