Transition lenses darken automatically when exposed to UV light and return to a clear state when no longer in contact with sunlight. This process is quick and seamless, and you won’t even notice it’s happening!

Transition lenses are available in various frames and tints to suit your style and prescription.

Photochromic Lenses

Unlike traditional prescription eyeglasses and sunglasses tinted with a permanent dark shade, photochromic lenses (also known as transition lenses) automatically adjust to changing lighting conditions. In bright sunlight, they become darker, while in dim light, they become lighter to prevent eye strain and glare. This makes them an excellent option for everyday wear, eliminating the need to switch between glasses and sunglasses. Using advanced technology, transition lenses utilize a thin layer of UV-blocking film to react with the sun’s rays. This causes the lens to darken when exposed to UV rays and return to its clear state when removed from the light. This allows you to enjoy maximum protection from harmful UV rays while still being able to see clearly in all environments. Transition lenses from online retailers like Zenni Optical are available in various stylish frames, from classic shapes like aviators to modern and daring styles. They also offer a range of colors and finishes to help you find the perfect look. Like all lenses, taking care of your transition lenses is essential to ensure they last long and provide optimal vision. Regularly cleaning your lenses with a specialized lens cleaner and using a UV protection spray will help keep them looking and performing their best. Additionally, avoiding exposing your transition lenses to excessive heat or cold can affect how quickly they change between states.

UV Protection

Transition lenses darken when exposed to UV rays, which helps protect against harmful rays that can cause eye strain and long-term vision damage. They also reduce glare and offer superior contrast perception, making them an excellent choice for outdoor enthusiasts. However, it’s important to note that transition lenses are not as effective in cold climates and can take longer than other tinted sunglasses to darken. Transition lenses use advanced photochromic technology to adjust tint based on lighting conditions automatically. They are clear indoors and become tinted in bright sunlight to protect from harmful UV rays. They tint to a lighter shade in dim light for comfortable indoor viewing. The photochromic dye in transition lenses is imbued into the lens material using a unique process called “imbibing.” This method allows the tint to be permanent and scratch-resistant. This technology helps make transition lenses affordable for people who want to eliminate the need for multiple glasses. Transition lenses are popular with fashion-forward Millennials and are featured in an exciting new TV spot that showcases fashionable glasses that effortlessly transition from clear to dark. However, only some may be good candidates for transition lenses due to personal preferences and unique visual needs. Consult an experienced optical professional to find the perfect pair for you.

Glare Reduction

Transition lenses are the ideal solution for those with problems seeing outdoors. They automatically adjust tint according to the amount of sunlight in your surroundings, becoming darker in bright sunlight to protect you from harmful UV rays and light glare that can make things look blurry. Then, when you move into dim lighting, the lenses fade to their clear state so you can see again without squinting. What’s more, they’re durable and scratch-resistant and are available in various colors like grey, brown, green, and blue, allowing you to find the perfect style to match your fashion sense. They’re also available with various coatings, such as polarization and anti-reflective, further reducing glare and eyestrain. Transition lenses use cutting-edge technology that causes them to change tint depending on the surrounding lighting conditions. The tinting is created with a special photochromic dye that’s either imbibed or applied to the lens surface using the Trans-Bonding method. Imbibed lenses are heat-embedded into the lens material, while the Trans-Bonding method applies the dye to the lens’ surface before adding a protective coating. Regardless of the lens type you choose, both offer superior performance.


Eyeglasses that darken when exposed to sunlight are in significant demand, especially among Millennials. A few years ago, it would have been unthinkable to suggest that this generation of consumers might embrace lenses that automatically lighten and darken in response to sunlight. This trend is in full swing today, with many fashion-forward young people opting to have Transitions lenses fitted into their prescription glasses. Transition lenses are available in a wide range of frames, so there’s something to suit every personal style. For optimal clarity, frames can be fashioned with standard plastic or polycarbonate lenses and various higher-index lenses. Some frames even offer polarization for added protection against harmful UV rays. It’s best to consult an experienced eye care professional for a suitable recommendation for those interested in a pair of transition lenses.
