For some people, wearing glasses isn't just a fashion statement or a way to complete an outfit; it's also necessary to address vision problems.
However, wearing prescription glasses outdoors, especially when the sun is shining brightly, can be uncomfortable. To protect your eyes from harmful sun rays, you'd have to switch between this set and use photochromic or transition lenses instead.
So If you're looking for photochromic lenses, you should know about photochromic lenses. In this article, To help you understand the benefits, we're covering everything you need to know about these underrated lenses.
Photochromic lenses, commonly referred to as transition lenses, are a type of eyewear that adapts to changing lighting conditions automatically. They are intended to darken in direct sunlight and lighten in low-light situations. For those who frequently travel between indoor and outdoor settings or spend a lot of time outside, this feature makes them quite convenient as they eliminate the need for multiple pairs of glasses or constantly switch between sunglasses and regular glasses.
Other terms used for photochromic lenses include "light-adaptive lenses" and "variable tint lenses." One of the most popular brands of photochromic lenses is Transitions, although other brands are also available.
Regular sunglasses block out particular wavelengths of light with either colored filters or polarisation. As photochromic lenses are carbon-based, the molecules react to UV; they change shape and absorb the light, making the lenses look darker.
When you step outdoors, UV rays from the sun hit your glasses, and the molecules inside your photochromic lenses will activate and darken.
The shades vary from clear to darker, depending on UV levels. The darkening can take up to 30 seconds for the tint to take effect on the glasses, and it can take between two to five minutes to return to normal when going back indoors.
They offer UV protection, which helps general eye health.
Photochromic lenses, made of plastic, glass, or polycarbonate, come in various prescription glasses choices for those with eyesight problems. In many cases, plastic photochromic lenses are preferred over glass because of their molecular makeup. Users find the tint on plastic lenses more evenly distributed than on photochromic glass lenses.
Is it worth using the transition lens? You can consider these pros and cons before figuring out if this lens is suitable for you.
Glass photochromic lenses are still widely used today despite being the first type of photochromic lens. They are composed of glass and are noted for their durability and scratch resistance.
Plastic photochromic lenses that are made of plastic, are a popular alternative for people seeking a lightweight and comfortable option. They are also less prone to break than glass lenses.
Polarized photochromic lenses combine the advantages of polarised and photochromic lenses. They are an excellent choice for outdoor sports like fishing and skiing since they give UV protection and reduce glare.
Photochromic lenses can be made with a prescription for those who need vision correction. It's important to consult with an eye doctor to ensure the right prescription is used.
When wearing the lenses, think about the activities you will be engaging in. A lighter color may be suitable if you plan to spend most of your time indoors. A darker shade might be better if you'll spend a lot of time outside.
Distinct photochromic lens manufacturers and types have different features and benefits, so it's crucial to compare them before making a purchase. This might assist you in determining the best alternative for your requirements and budget.
