Home » What Are Transition Lenses and How Do They Work?
Because the lenses adjust to changes in light, they help you consistently see better. The lenses react to the sun’s UV rays. Special dyes in the lenses cause them to change color with exposure to light, becoming dark when you need protection from sunlight and glare. They help you discern brightness and contrast to allow you to see with clarity in all light locations.
Advances in technology allow glasses to remain clear indoors but dark in bright conditions outdoors. The transition from normal eyeglasses to sunglasses occurs automatically in the sun and with a return to indoors. While they provide UV protection in light or dark conditions, they let you see better indoors or out.
The sun’s ultraviolet radiation makes molecules in the dyes react by becoming dark. You do not necessarily need direct sunlight for transition lenses to work. Exposure to UV rays and harmful blue light occurs many times every day from indoor lighting, the sun, and electronic devices. Even on cloudy days, you need 100 percent protection from UV rays. An Odessa optometrist can help you find the lenses that help you achieve the vision you prefer.
