Can Transition Lenses Have Blue Light Filtering Tints?
The simple answer is yes, you can get transition lenses that also have a blue light filter. Transition lenses, also known as photochromic lenses, adjust their tint in response to UV light, providing protection from bright sunlight. Many optical retailers now offer options that combine this feature with a blue light filter, which helps reduce exposure to blue light emitted by screens and artificial lighting.
Essilor Transitions Gen 8
The Essilor brand of Transitions Gen 8 comes with blue light filtering built-in. It’s not an extra feature that needs to be added.
The Theory Behind Blue Tinted Lenses
The theory behind wearing yellow-tinted lenses, which help reduce blue light, is rooted in the body's natural response to light. The phrase goes that ‘blue helps us to wake up, red helps us to sleep’, and this is not so far removed from how our ancestors lived. These lenses can be beneficial, but there are also considerations to take into account.
Blue Light Filtering for Screens
Computer manufacturers recognize the importance of reducing blue light emission in the evening. If your computer has an option to reduce blue light emission, then blue-filtering lenses might not be necessary for you.
Photochromic Lenses vs. Blue Filtering Tints
If you are considering photochromic lenses, which are usually intended to darken out of doors, you might question whether an additional blue-filtering tint is what you need. The residual tint from the photochromic lens might interfere with the functionality of the blue-absorbing tint you desire for evenings. Your eye-care professional will be able to advise you on this.
It's worth noting that many eye-care professionals, including myself, do not wear blue-absorbing tints as we believe they are generally not necessary and are a waste of money. They are often used for visual comfort and protection in certain situations.
Conclusion
Blue-light filtering lenses can be beneficial, especially for those who spend a lot of time in front of screens. However, they may not be necessary or effective when you already have photochromic lenses or if your screen has a setting for reducing blue light. Consult with an eye-care professional to determine the best solution for your needs.
