If you regularly wear specs to aid your vision, at some stage you’ve probably had a moan about them when you’ve been out in the sunshine. It’s annoying having to switch your optical glasses for your prescription sunglasses when you change environments; it’s more irritating if you don’t have prescription sunglasses or you’ve forgotten to pop them in your bag or car; what about when you’re reading a book by the pool on holiday?
These are all minor complaints, but when these situations arise regularly it can become a daily annoyance. You want to protect your eyes from harmful UV rays, but at the same time you need to be able to see; ideally without having to carry more than one pair of glasses around with you!
So what about transition lenses? Also known as photochromic lenses, these clever lenses change from clear to dark on exposure to ultraviolet light. They change really quickly, so when you walk outside in your specs the lens will immediately change colour, protecting your eyes from damage.
Here’s the science part… each lens comprises of photochromic molecules. These molecules change structure when they’re exposed to UV light, which allows the tint of the lens to change depending on brightness. They do their job so well that they actually block 100% of UVA and UVB light from entering your eyes. This means that you are protected from some of the damage that UV can cause, such as cataracts, macular degeneration, and sunburn of the eye.
Transition lenses also reduce glare in bright sunlight, so they really are a champion in the world of optical lenses!
However, traditional transition lenses don’t protect your eyes in all situations. When you’re driving, the windscreen blocks the UV rays that trigger the change in the lenses. At Eye Emporium we still have a solution for you though; Transitions XTRActive lenses can be used when it’s not too bright. But even better, Transitions Drivewear lenses react to visible light instead, so they still change to protect your eyes and block glare. They are also polarised, which means your vision will be at its optimum!
We also recommend Transitions Vantage lenses, which boast variable polarisation, and Transitions Performance lenses for those who need their vision to be second to none when playing sports or driving.
Finally, you can even have your transitions lenses tinted if you’re a keen sportsman or woman. You may already know that certain coloured tints on your lenses can create a better contrast in certain environments (brown and purple tints are fantastic for a green golf course for example). Now there is a range of tinted transitions that take into account the benefit of coloured lenses, so you really can rely on one pair of glasses for everything!
