Everyone wants high quality glasses. There are tons of different frames, and it seems as though every fashion designer is getting into offering something. However, in the end, it is all about the lenses that go into the frames. Photogray extra glass lenses are technologically advanced transition lenses that make it easier to go from indoors to outdoors without having to make the switch to a different pair of glasses. Understanding the technology makes it easier to learn just how great these glasses can be. The transition and light-adaptive lenses can make all the difference in the world when you want convenience.
Photochromic lenses are essentially lenses that are clear indoors and then darken automatically whenever they come into the sunlight. Depending upon who is marketing the eyeglasses, they may be referred to as variable and or light-adaptive lenses. Regardless of what they are called, they are all capable of doing the same thing.
Transition Lenses is an actual brand, and is one of the most popular brands within the United States. The reality is that even eye care practitioners will often refer to photochromic lenses as transition lenses, and they are referring to the technology, not necessarily the brand. There are plenty of other brands, and they generally use the same technology.
There are molecules inside of the photochromic lenses that will darken as they are activated by the UV rays of the sun. Even on overcast days, the lenses will darken, and this is because UV rays are capable of penetrating the clouds. One thing to understand is that photochromic lenses will not darken usually inside of the vehicle, and this is because the windshield and other auto glass is capable of blocking UV rays. Some of the most recent technological advancements allow the lenses to activate with both visible and UV light. This means you will want to explore what the glasses are capable of before you make the purchase.
One of the really cool things about photochromic lenses is that they are available in just about every lens material and design that you could ask. This includes progressive lenses, bifocals, and high index lenses. When you want to shield your eyes, you can also enjoy peace of mind that the photochromic lenses will block out 100% of both UVA and UVB rays from the sun.
Even though photochromic lenses are going to be more expensive than traditional eyeglass lenses, they are actually the more valuable option. This is because you won’t have to have a pair of reading glasses and a pair of prescription sunglasses. You can simply have one pair of glasses everywhere you go because the lenses will adapt to where you are.
Transitions Optical is one of the most popular brands within the United States. You will also be able to find options from LifeRx, Carl Zeiss Vision, Signet Armorlite, Corning, and more.
PhotoGray is another popular term for transition lenses, though it is actually a brand. It is one of the lines from Corning, and they offer superior scratch resistance at the same time. They have been in production from Corning since the 1960s, and you can find the glass lenses in both gray and brown tint. This allows you to gain the aesthetics that you desire without having to compromise on your personal style.
The technology is the same regardless of the brand you purchase. Knowing your options will make it easier to ensure your vision needs are met.
