LifeRx Light-Responsive Lenses by VISION EASE

LifeRx Photochromic Lenses

What are light-responsive lenses?

Light-responsive lenses adjust to changing light conditions. Indoors, the lenses are crystal clear. Outdoors, the lenses darken based on the amount of UV (light) exposure. The brighter the light, the darker the lens. Light-responsive lenses are also known as photochromic, variable tint or changeable tint lenses.

In any everyday environment—subway or street, playground or porch—the best-in-class technology of LifeRx light-responsive lenses permits a seamless flow from outdoors to indoors and back again. They make eyeglasses more versatile and provide 100% UV protection, reaching sunglass tint in less than a minute.  Providing the ultimate comfort and convenience, you’ll love the fact that you don’t have to think about LifeRx lenses.

Our photochromic dye is formulated to fade back faster than leading photochromic lenses so there’s no more waiting. Tired of lenses that remain somewhat tinted, hiding your eyes? Our highly sensitized polycarbonate resin allows the dye to become crystal clear getting rid of the unwanted indoor tint.

The perfect everyday lens for all ages and lifestyles.

Who benefits the most from wearing light-responsive lenses? Almost every eyeglass wearer will enjoy the convenience and comfort of LifeRx lenses, and almost everyone is a good candidate. Those who can benefit most are:

  • Post-surgical patients: They often become more light-sensitive.
  • Contact lens wearers: They need glasses but don’t want to invest in multiple pairs.
  • Presbyopes: As near vision changes with age, the eye’s ability to adjust quickly to changing light conditions is also reduced.
  • Children: Kids love light-responsive lenses, and LifeRx technology offers the durability their active lives demand. Spending time outdoors, they need protection from UV radiation. Excess ambient light can cause headaches and fatigue.
  • People with active and outdoor lifestyles: They need protection from UV radiation and excessive ambient light. They can’t always be bothered to switch glasses.
  • People who participate in outdoor leisure activities, such as gardening or golf, or who walk a great deal in their everyday lives: They need light-responsive polycarbonate lenses that adjust to allow the optimum levels of light transmission in varying light conditions.
