Which is Better - Transition or Photochromic Lenses
When it comes to choosing lenses for your eyeglasses or sunglasses, you may be faced with the decision between transition lenses and photochromic lenses. While these terms are often used interchangeably, they actually refer to two different types of lenses.
Transition lenses are a brand of photochromic lenses manufactured by Essilor. These lenses darken when exposed to UV light, such as sunlight, and then return to their clear state when the UV light is no longer present. They are designed to provide convenience and protection to wearers by automatically adjusting to changing light conditions.
Photochromic lenses, on the other hand, are a type of lens that darken when exposed to UV light and then return to their clear state when the UV light is no longer present. They are available from a variety of manufacturers, including Essilor, Zeiss, and Hoya, among others.
What are the Differences Between Transition and Photochromic Lenses? While transition lenses and photochromic lenses both darken in sunlight and return to their clear state in normal lighting conditions, there are some differences between the two.
Tint Range:
Transition lenses are known for having a limited tint range. They are designed to darken to a specific level and may not get dark enough to provide adequate protection in very bright conditions. Photochromic lenses, on the other hand, can have a wider range of tinting and may be able to provide more protection in very bright conditions.
Transition Time:
Transition lenses are also known to have a slow transition time, meaning that they can take several minutes to fully darken in bright sunlight. Photochromic lenses, depending on the manufacturer, may have a faster or slower transition time.
Lifespan:
Because transition lenses are a specific brand of photochromic lenses, they may have a shorter lifespan than other photochromic lenses. However, this can vary depending on the quality of the lens and the manufacturer.
So, which is better? transition or photochromic lenses? Ultimately, the decision between transition lenses and photochromic lenses comes down to personal preference and needs. If you are loyal to the Essilor brand or prefer the limited tint range of transition lenses, then they may be the better choice for you. However, if you require a wider range of tinting or a faster transition time, then a different brand of photochromic lenses may be a better fit.
When choosing lenses for your eyeglasses or sunglasses, it is important to consult with your eye care professional to determine which type of lens is best for your needs. They can help you understand the differences between transition lenses and photochromic lenses and help you make an informed decision.
