What Types Of Photochromic Glasses Can You Get

Transition Lenses Brown vs Grey

Today, there are a wide variety of photochromic lenses on the market. You can get them in an array of styles designed to fit your needs. Examples include:

  • Sports eyewear. Only certain types of eyewear are safe to use during athletic events. These include polycarbonate and trivex materials. Transition lenses are available in both varieties.
  • Coated lenses. Photochromic lenses donât interfere with the particular types of coating that people like to have on their lenses. For example, anti-reflective coatings help reduce glare and are good for night driving. Water-repellant treatments prevent your lenses from misting over when you move from the cold outdoors to warm indoor environments.
  • Colorful lenses. Traditional photochromic lenses were only available with a gray tint. But normal sunglasses can come in a wide range of colors. These days, you can get photochromic lenses that are brown or green. The range is still not as broad as for traditional sunglasses, so they may not be available in your preferred color.
  • Bifocal, multifocal, and high-index options. Certain lenses are designed to deal with particular vision problems. Photochromic lenses are available for most common types of vision-correcting eyewear. For example, bifocal versions help people who have a hard time seeing both far away and up close. High-index options are helpful for people who need strong prescriptions.

What Are Photochromic Lenses Made Of

These days, glass lenses are far less common than newer synthetic materials. Most lenses are made from some type of plastic or resin.

There are many ways to produce resins and infuse them with the necessary dyes. This makes them a more flexible material to work with compared to glass.

There are a variety of brands of photochromic lenses to choose from. Different brands construct their lenses from different base materials and dyes. So â even though all photochromic lenses work in approximately the same way â the variations in materials alter the characteristics of the lenses, including their rate of color change.

The frames for your lenses can come in all types of materials, including metal and plastic.

How Do Photochromic Lenses Work

The light-sensitive molecules inside photochromic lenses shift their structure when theyre bathed in UV rays, allowing them to absorb more light and give the lenses a darkened appearance. Once the UV light goes away, the process reverses and the lenses become clear again.

These photochromic molecules are sensitive to both the presence and amount of UV light. Theyll change their structure more quickly when exposed to a lot of it, and more slowly if theres only a little bit. Thats why you might notice your photochromic lenses darkening a bit less in the shade than out in the sun.

However, you dont need to be standing directly in a sunbeam to get a dose of UV rays. UV light penetrates the clouds, and your photochromic lenses will still darken under overcast skies.

Want a closer look at how photochromic lenses work? Well, its a slightly different chemical reaction depending on the material of the lens.

Benefits Of Photochromic Lenses

Because a persons lifetime exposure to sunlight and UV radiation has been associated with cataracts later in life, its a good idea to consider photochromic lenses for childrens eyewear as well as for eyeglasses for adults. Polycarbonate is the safest lens material for kids, providing up to 10 times the impact resistance of other lens materials.

Adding anti-reflective coating to photochromic lenses enhances their performance even further. AR coating allows more light to pass through photochromic lenses for sharper vision in low-light conditions , and eliminates bothersome reflections of sunlight and other light from the backside of the lenses in bright conditions.

Though photochromic lenses cost more than clear eyeglass lenses, they offer the convenience of reducing the need to carry a pair of prescription sunglasses with you everywhere you go.

    Different Kinds Of Photochromic Lenses

    There are many brands of photochromic lenses available in America. The most popular one, and the one that is most often cited when talking about photochromic lenses, is Transitions Optical.

    In some ways, Transitions Optical has become synonymous with photochromic lenses, In July 2019, Transitions Optical introduced the Transitions Gen 8 lenses, which are the fastest light-adaptive lenses the company manufacturers. It takes 30 percent less time for the lenses to activate in the appropriate lighting conditions.

    Also developed by Transitions Optical are Transitions XTRActive, which are lenses intended for people who are light-sensitive indoors and want a darker lens when they are outdoors or have to drive. These lenses have a slight tint for indoor use, which keeps the eyes comfortable when they are exposed to digital device screens, fluorescent lights, and other forms of glare and harsh lighting.

    Transitions Optical has also developed Transitions Vantage, lenses with a minimal indoor tint and a stronger polarization effect for outdoor darkening. This offers users a better degree of glare control in conditions that are bright and reflective. The polarization constantly adjusts when the glasses are outdoors, as a way of matching the level of the reflective glare. According to the manufacturer, this gives patients a âhigh-definition visual experience.â

    How Do Acuvue Oasys With Transitions Lenses Work

    These Acuvue contacts have Transitions’ “Light Intelligent Technology” — a — mixed into the soft hydrogel material that creates the lens. When this photochromic additive is exposed to UV light or blue light from screens and lightbulbs, it darkens the lens to block UV radiation and excessive light waves, just like sunglasses do.

    The contacts adjust throughout your day to allow a consistent amount of light to reach your eye, whether you’re in a dark theater or outside under the sun. When your eyes are exposed to UV light, the lenses take around 45 seconds to fully darken. Once you step inside, they go back to clear in about 90 seconds or less.

    I should note that Acuvue’s other contacts, and contact lenses from other brands — such as Biotrue and Clariti — also block UV radiation, but stay clear in all light.

    Benefits Of Glasses Without Nose Pads

    Glasses without nose pads are mostly used for sheet materials because the sheet material is lighter and not allergic. From the viewpoint of aesthetics and comfort, no nose pads are more suitable. Glasses without nose pads have a relatively small contact area with the bridge of the nose, so it is not easy to have obvious indentations on the bridge of the nose, while glasses with nose pads will have obvious indentations after wearing them for a long time.

    In addition to supporting the frame, the nose pad has another function to prevent allergies and avoid discomfort caused by allergies to metals or other materials. Whether it is better to have glasses with nose pads or without nose pads, depends on your personal situation. If your nose is sensitive to weight or the bridge of your nose is lower, you should choose glasses with nose pads. If you are particularly looking for beauty and don’t want any marks on your face, then choose glasses without nose pads.

    In fact, it is hard to say which one is better between nose pads and no nose pads. The key is to look at personal preference and wearing comfort. Generally speaking, a high nose bridge is suitable for choosing frames without nose pads. It is more suitable to choose the frames with nose pads for people with flat nose bridges in order to prevent the glasses from sliding off and affecting the visual effect.
