There are a few cons of transitions lenses:
- They don't work in a car because the windshield blocks the UV rays that are necessary to initiate the lenses' darkening mechanism. However, some manufacturers currently have car-friendly lenses in the works. If you own a convertible you can ignore this point.
- Transitions lenses aren't polarized just yet. If you wear prescription eyeglasses and you are light sensitive, the lenses won't reduce the hard glare. On a positive note, this feature should be available in approximately 6 months. Several manufacturers do make polarized non-prescription lenses.
- You may have to take off your glasses for outdoor photos. Since the lenses darken as soon as you walk outside, your eyes will be obscured in pictures. If you're trying to cultivate the rock star look, you can add this to the pro column.

What else can I help you with?
Is it possible to change clear lenses to transitional lenses?
No, clear lenses cannot be changed to transition lenses. Transition lenses have a special treatment that reacts to UV light to darken in sunlight, which cannot be added to regular clear lenses. You would need to purchase new transition lenses to have this feature.
Is there sunglasses that you can also see with?
Yes, there are sunglasses available with lenses that can transition from dark to clear when exposed to sunlight. These lenses are called photochromic or transition lenses, allowing you to wear your sunglasses indoors or at night as they adjust in darkness.
Can you swim with transition lenses?
Yes, you can swim with transition lenses. However, prolonged exposure to chlorine or saltwater can damage the lenses over time. It's recommended to rinse the glasses with fresh water after swimming to help preserve the lenses.

How do photochromatic lenses work?
Photochromatic lenses are commonly called transition lenses. The lens is clear, but when exposed to the sun's UV rays, they will darken like sunglasses.
What are transition lenses and how do they work to darken in the sun?
Transition lenses are a type of eyeglass lenses that automatically darken when exposed to sunlight. They contain special photochromic molecules that react to UV light, causing the lenses to darken. When the UV light diminishes, such as when indoors, the lenses gradually return to their clear state. This allows the lenses to provide both vision correction and sun protection without the need to switch between regular glasses and sunglasses.
How do transition lenses work to darken in the sun and lighten indoors?
Transition lenses contain photochromic molecules that react to UV light. When exposed to sunlight, these molecules darken to protect the eyes from harmful UV rays. Indoors, where UV light is minimal, the molecules return to their clear state, allowing the lenses to lighten.
How much are transition lenses?
The price of transitions lenses will depend both where one buys them and exactly what type of transitions lens. Most of the time transitions lenses cost between $25 and $50 though can be as high as $100.
Transition lenses in the freezer?
Putting transition lenses in the freezer is not recommended. Extreme cold can damage the lens material and affect their ability to transition properly between clear and tinted states. Additionally, the rapid temperature change may cause stress or warping. It's best to follow the manufacturer's care instructions for optimal performance and longevity.
How do transition lens work?
Transition lenses contain photochromic molecules that darken when exposed to UV light, and become lighter when the UV light diminishes. This allows the lenses to automatically adjust to different lighting conditions, providing both clear vision indoors and UV protection outdoors.
How do self-tinting glasses work?
Self-tinting glasses, also known as photochromic lenses, contain photochromic molecules that respond to UV light. When exposed to UV radiation, the molecules in the lenses undergo a chemical process that causes them to darken, providing protection from sunlight. Once the UV light is removed, the lenses gradually return to their clear state.
Which bifocal lenses provide the smoothest transition from close-up view to far view?
try RGP bifocul lenses as a starting point but please check with an optomotrist becauses they can tell you which one is the best.
