What experts liked

These are comfortable and they are clear or darker based on the amount of sunlight. I really like this feature as I often start or end rides in different light conditions and don’t want to be changing glasses mid ride.

I don’t think they ever get super dark

An Overview On Photochromic Glasses

If you live an active lifestyle where you are constantly going from outside to inside and vice versa several times a day, it can be frustrating having to put on your sunglasses every time. With photochromic lenses, you don’t have to worry about carrying that extra pair of sunglasses with you – because regular glasses can actually turn into the perfect pair of sunglasses.

Photochromic glasses work when they are exposed to UV light. The lenses contain trillions of photochromic molecules. These change structure when UV light shines upon them. As a result, the changing of the molecular structure allows the lenses to darken. Not only that, but photochromic lenses darken based on the amount of UV light they are exposed to. For example, if they are exposed to just a small amount, they will only darken slightly versus if they are exposed to a large amount, where they will darken fully.

There are many reasons to choose photochromic glasses. They help to reduce eyestrain by blocking the glare of the sun. Have you ever stepped outside and immediately had to squint because the sun was so bright compared to being indoors? This uncomfortable feeling is alleviated when you wear photochromic glasses. These glasses also protect the eyes from harmful UV rays by actually absorbing the rays before they reach your eyes.

Photochromic glasses are available for most prescriptions, so most people who wear glasses can enjoy their benefits. Plus, they ensure you no longer have to juggle between multiple pairs of glasses or worry when you forget the sunglasses at home. Photochromic glasses are available in many different designs, so no matter what your aesthetic is, you can find a style that looks good on you.

The Photochromic Glasses Buying Guide

  • It’s important to note that not all photochromic lenses darken to the same degree. It will depend on the brand and the quality of the lens. When choosing photochromic glasses, be sure to read the product description in detail so you can understand how long the lens transition time is and how dark the glasses actually get. Where available, be sure to check out customer reviews so you know what to expect.
  • Did you know that in addition to being sensitive to light, some photochromic glasses are actually sensitive to temperature? In some photochromic glasses, if you are in freezing temperatures, the glasses may take longer to darken. In warm temperatures, photochromic glasses tend to work faster.
  • If you work outdoors or spend a lot of time outdoors, you may want to get photochromic sunglasses. These types of glasses are not really made for indoor use, and as a result they don’t get as clear as regular photochromic glasses. Instead, they remain slightly tinted in dark conditions. They work well for people who work in different types of outdoor conditions during the day.
  • What happens when you’re outside on a sunny day but sit in the shade? Depending on how much UV light is present in the shade, your photochromic glasses will automatically adjust to become lighter, giving you more clear vision when you’re in the shade.
