Two thousand twenty-four clear frames will take center stage, delivering elegance and simplicity. They adapt seamlessly to varying light conditions, offering an innovative blend of comfort and convenience.
Photochromic lenses are a game changer: step outdoors, and they instantly darken to become sunglasses; step back indoors and quickly clear up. This versatile eyewear is a must-have for anyone on the go.
Transition(tm) Lenses
What are the glasses that turn into sunglasses? The most common kind of photochromic lenses darkens in response to ultraviolet light. They’re the ideal option for regular sunglasses and eyeglasses. Multiple frame designs, sizes, and prescriptions are available for these lenses. Almost all lightweight lens treatments and materials are compatible with them.
The secret behind transition lenses is the special silver halide and chloride tint embedded within them. The lenses are straightforward until they’re exposed to UV light, which causes trillions of molecules within the lens to change their structure and darken. Once you’re back indoors and less exposed to UV light, the lenses return to their original appearance.
Having one pair of glasses that functions as both your every day glasses and sunglasses saves you the time and effort of constantly switching between two pairs. In addition, the tint on the lens reduces glare and eye strain, making it easier to see in bright conditions. Transition lenses are available in various colors and work with prescription and non-prescription frames. They can also be added to single-vision, bifocal, and trifocal lenses.
Auto-Tint
If you wear glasses or sunglasses, you have probably experienced the frustration of suddenly having your spectacles tinted on you without your control. The lenses are coated with a dye that changes color based on UV light.
A new self-tinting lens technology allows you to enjoy the benefits of transitions and have complete control over when your lenses tint. The Optovision e-Tint system uses photochromic molecules that react to UV light, closing up like miniature parasols when exposed to sunlight and lightening again when the sun goes down.
This technology is available on all frames and lenses, including single-vision, bifocal, and progressive lenses. It can be applied to both clear and prescription sunglasses. It can also be combined with polarized lenses for increased visual comfort while using digital devices and enhanced contrast while driving. One of the best features of this technology is that it can filter harmful blue light emitted by many digital displays and screens, improving comfort for people who spend long periods on their phones, tablets, and computers.
Convenience
Photochromic lenses eliminate the need for two pairs of glasses, one with prescription lenses and another with sunglasses, a significant benefit for those who frequently transition between indoor and outdoor settings. These lenses are also designed to reduce eye strain by adjusting tint levels in response to changing light conditions.
When a person enters sunlight, photochromic lenses darken automatically because they absorb ultraviolet (UV) radiation. They then return to their clear state when UV radiation is removed from the lens surface. These lenses also protect the eyes from harmful blue light, which is emitted by sunlight, as well as by modern technology such as LED TVs and cell phones.
These lenses are available in various styles to suit individual preferences and activities, including single-vision, bifocal, and progressive lenses. They are also cost-effective in the long run because they eliminate the need for two pairs of eyewear and protect against harmful UV rays. However, some drawbacks of these lenses include a longer activation time, temperature sensitivity, and limited tint range.
Versatility
Versatility refers to the capability of being flexible and adaptable to various situations and functions.
Photochromic lenses adjust to the light conditions in your environment automatically, providing optimal tint levels for visual clarity and eye protection. These lenses have built-in UV protection to safeguard against long-term eye damage caused by harmful UV rays.
Photochromic lenses are available in various frame styles and sizes and can fit into prescription or non-prescription sunglasses. That makes them an excellent choice for individuals of all ages and lifestyles. Photochromic lenses can be combined with other lens features, such as polarized filters to reduce glare and enhance optical clarity or anti-reflective coatings to minimize reflections. It provides added versatility and helps you achieve a personalized eyewear look that is comfortable, stylish, and convenient. You can even choose a tint color that complements your personality, such as a cool blue hue or a subtle pink shade.
UV Protection
Photochromic lenses automatically adjust to varying light conditions, eliminating the need for separate sunglasses and eyeglasses. The technology offers a seamless blend of comfort and convenience, making it an ideal choice for those who spend a lot of time indoors or outdoors.
Embedded within your lenses is a silver chloride compound that reacts to light. When exposed to UV rays (also known as UVA and UVB), the lenses darken, protecting your eyes from harmful glare caused by sunlight. Once the glasses are removed from UV light, the lenses return to a clear state, similar to sunglasses.
Although seamlessly transitioning between two types of frames is a significant perk, photochromic lenses have some drawbacks. For one, they can take a little longer to darken in cold weather. Additionally, they may not entirely block all the UV rays that reach your eyes through car windshields or indoor lighting. Speaking with your eye care professional about your needs can help you decide whether photochromic lenses suit you.
