FAQ
What are photochromic glasses?
Photochromic glasses are lenses that darken when exposed to sunlight and clear up indoors, providing both UV protection and convenience.
How do photochromic lenses work?
These lenses contain special molecules that change structure when exposed to UV light, causing them to darken. When the UV light is removed, the molecules return to their original state, and the lenses become clear again.
Are photochromic lenses suitable for driving?
Photochromic lenses may not darken as effectively inside a car because the windshield blocks most UV rays. For driving, consider polarized lenses for better glare reduction.
Do photochromic lenses work in all weather conditions?
Yes, photochromic lenses adjust to varying light conditions, but they may take longer to transition in extremely cold temperatures.
Can I get prescription photochromic lenses?
Absolutely! Photochromic lenses are available in both prescription and non-prescription options to suit your vision needs.
Are there different types of photochromic lenses?
Yes, photochromic lenses come in various colors and materials, including plastic and polycarbonate, to match your style and needs.
How long do photochromic lenses last?
The effectiveness of photochromic lenses can diminish over time, usually after about two to three years of regular use.
Are photochromic lenses more expensive?
Photochromic lenses typically cost more than regular lenses due to their advanced technology, but they offer the convenience of two-in-one functionality.
