If you have glasses, you are undoubtedly aware of the struggle that comes with having to change to your sunglasses every time the sun appears. Of course, the invention of transition lenses, also known as photochromic lenses, has made this a problem of the past for countless eyeglass wearers. But can these lenses be made better?
Transition lenses are clear when in the absence of any activating light. Once ultraviolet radiation (typically from the sun) hits the material, sensitive molecules embedded in the lens cause them to darken. Not only does this protect the eyes, but it also allows for greater visibility. Plus, once the UV light source is removed, the lenses quickly revert to their clear state.
Technological Improvements
The new technology that makes use of nanostructuring has dramatically improved the performance of the latest transition lenses. Not only are they fully clear indoors, but they darken to a far greater degree upon exposure to light. The process – which used to take nearly a full minute – now happens nearly instantaneously, blocking 100% of UV light and harmful blue light, offering far greater protection to the retinal cells.
Can You Make Transition Lenses Darker?
Of course, there are situations in which you might want additional performance from your transition lenses. You might be driving, for instance, and find that the windows of the car are preventing the lenses from triggering correctly. Perhaps you're in a high-glare situation, such as in the snow or near the water. Whatever the case, if you want darker darks from your lenses, there are a few things to consider.
1. Transition Lenses Perform Best in the Cold
In high temperatures, photochromic lenses tend to darken far less than they would in colder situations. This means that if you're out hiking dunes, for instance, you might want to opt for traditional prescription sunglasses. Alternatively, you can do your best to keep the lenses cool. Though some people recommend sticking their glasses in the cooler, turning on the AC (if driving) or wearing a hat can work as well.
2. Consider Tinting Your Lenses
If you're particularly photosensitive, you might want to consider adding some additional tinting to your transition lenses. This will keep them from reverting to a completely clear state; it will also allow them to reach a darker shade during transitioning. You'llYou'll likewise gain protection from harsh indoor lighting, which might not trigger your lenses otherwise.
3. Consider New Lenses
We already mentioned that new transition lenses incorporate technology that allows them to get darker. However, you also need to understand that your lenses might lose their transitioning abilities over time. When this happens, they tend to take on a bit of a yellowish tint, and they no longer function as well outdoors. So, if your lenses are old, it might just be time for a new set.
