Sunglasses are some of the most popular fashion accessories. And for obvious reasons. They have the ability to instantly make any outfit cooler. Let us take in the view without squinting.

How Often Should We Do Sunglasses Lens Replacement?
More than just a fashion accessory. The main purpose of sunglasses is to protect our delicate eyes from harmful UV radiation. Whenever walking outside, having maximum UV protection for your eyes should be a top priority. Overexposure to UVA and UVB rays can cause ocular cancer, macular degeneration, permanent eye damage. And even blindness in more serious cases.
But even short term exposure can result in photokeratitis which is sunburn of the cornea. That causes temporary pain, swelling, light sensitivity and loss of vision. Photokeratitis is also colloquially known as “snowblindness”. So you might have already experienced this if you’ve spent too much time around water or snow without eye protection.
Do All Sunglasses Offer Protection?
Even though all tinted sunglasses can shield from sunlight to some degree. And allow you to stay comfortable on a sunny day or even at night. Not all of them offer UV protection. Unfortunately, it’s not obvious whether a pair of sunglasses offers optimal UV protection or not. Even pairs with a UVA400 tag no are no guarantee. The only way you can be sure your eyes’ health is protected is to purchase sunglasses from trusted brands.
Brands like Oakley, Ray-Ban, Revo, Otis, BLUPOND and similar manufacturers of quality eyewear. However, it’s important to know that a pair of quality sunglasses doesn’t offer lifetime protection. Sunglass lenses have an expiration date which is determined by a variety of factors. So, once that time comes, they are no longer able to offer optimal UV protection. And are as good as a pair of sunglasses bought from the supermarket.
Why Do Lenses Lose Their Efficacy?
A study by the University of Sao Paulo, Brazil. Found that the lenses in sunglasses lose some of their UV-blocking capability over time. The researchers tested a variety of lenses. And discovered that the protective coating on the lenses breaks down over time from the usual wear and tear. And this damage to the protective coating isn’t always visible.
If you had the habit of stuffing your sunglasses in your bag or your jacket’s pocket without a protective case. They may be covered in tiny, invisible abrasions that reduce the efficacy of your lenses. And once the lenses’ efficacy decreases, it can’t be restored. But even if you stored your shades in a protective case and treated them with extra care. There’s still no guarantee that the lenses have preserved their protective ability.
Can I Change Sunglasses Lens Color?
Yes, you can. Also just to add, the protective dyes and pigments are gradually broken down by the radiation. So the more sunlight your sunglasses are exposed to, the more quickly the lenses become ineffective. In other words, even if you managed to keep your stylish shades in mint condition for the past five years. It’s likely that they do not live up to their name today.
Is it Worth it to Buy Sunglasses Lens Replacement?

When to Replace Sunglasses Lenses?
The answer to this question isn’t the same for everyone. As obviously the deterioration of the lenses depends on how they’ve been handled. Wow long they’ve been exposed to sunlight and the intensity of that exposure. However, the same study by the Brazilian scientists suggests. That the UV coating in most glasses deteriorates after two years of using them two hours a day. So, if you wear sunglasses for a normal amount of time.
