This is where photochromic lenses come in. These lenses are designed to automatically adapt to the amount of light that is present around them. So, when there is a lot of sunlight around, the lenses will darken, and when there is less light, they will clear up. This makes them an ideal choice for all weather conditions and situations.
Photochromic lenses were initially developed for use in eyeglasses. Still, they quickly caught the attention of the sunglasses industry due to their versatility and practicality. Today, photochromic lenses are a popular choice for people who enjoy outdoor activities such as sports and hiking.
But what exactly are photochromic lenses, and how do they work? Let's take a closer look.
How Photochromic Lenses Work
Photochromic lenses are made up of special molecules that react to light. When these molecules are exposed to UV radiation, they begin to change structure. This change in structure causes the lens to darken, which helps to reduce the amount of light entering the eye.
The darker the lens, the more UV radiation it has absorbed. Therefore, the process is entirely automated, which means that you don't have to worry about fiddling with any buttons or switches to activate or deactivate the lens.
Photochromic Lenses VS Polarized Lenses
Although photochromic lenses and polarized lenses may appear to serve the same purpose, they are entirely different. Photochromic lenses are designed to adjust their darkness levels based on the amount of light in the environment, whereas polarized lenses are designed to reduce glare.
When sunlight is reflected off a flat surface such as a road, water or a snow field, it creates intense glare. This type of glare can be extremely dangerous, especially when you're driving, and it can also be extremely uncomfortable. Polarized lenses are designed to block this type of glare, making them an ideal choice for outdoor sports such as fishing.
Benefits of Photochromic Lenses
There are many benefits to wearing photochromic lenses. They include:
1. Versatility - Photochromic lenses are designed to automatically adjust to the lighting conditions around them, making them suitable for all weather conditions.
2. Comfort - Photochromic lenses allow you to stay comfortable in any lighting condition, as you don't have to worry about changing lenses.
3. Convenience - With photochromic lenses, you won't have to carry around multiple pairs of sunglasses or lenses, as they adjust according to the lighting conditions.
4. Protection - Photochromic lenses provide full protection from the sun's harmful UV rays, reducing your risk of eye damage.
5. Fashionable - Photochromic lenses are available in a variety of styles and colours, making them a fashionable choice for any outfit.
Conclusion
Photochromic lenses are a fantastic replacement for traditional sunglass lenses. They provide versatility, comfort and convenience. They also offer full protection from the sun's UV rays and come in a range of styles and colours.
Whether you're a fashion-conscious individual, an outdoor enthusiast or someone who just loves the convenience of having one pair of sunglasses for all weather conditions, photochromic lenses may be the perfect option for you. Be sure to ask your optometrist about them the next time you're in for an eye exam.
