How long does UV protection last on sunglasses?

Does UV protection last on sunglasses? 

When buying designer sunglasses, often look for UV labels that indicate that the lens provides 100% protection against all harmful sun rays.

However, you have little to think about how long UV protection will last, especially if you spend a lot of time in the sun and wear many glasses.

Recent studies on UV protection sunglasses lenses may require you to change sunglasses more often than you think, and scientists recommend changing sunglasses at least every two years.

Most high-end designer sunglasses, such as those purchased from Ray-Ban and Oakley, claim 100% protection against harmful UV rays.

There is no reason to doubt this claim, but a research article published in Biomedical Engineering Online raises industry concerns.

The report argues that prolonged exposure to the sun can degrade some lenses, not only at the level of UV protection they provide but also at the level of impact resistance.

Sunglasses are more than fashion accessories-whether you are a trendsetter or not; they are essential to eye health! The UV blocking properties of sunglasses make your eyes look good in bright outdoor light while protecting your eyes from short-term and long-term damage from UV radiation. No one wants to experience vision loss, retinal damage, cataracts, macular degeneration, or other similar problems. These are the types of issues that can occur without proper UV eye protection, regardless of age or geographic location.

With that in mind, how do you know that you get the best UV protection from your sunglasses? Is it valid for life?

How to choose best

Pay close attention to how they are labeled and only purchase those rated as “100% UV protection” or UV400. Both show that sunglasses absorb the entire spectrum of UV wavelengths (UVA and UVB) and reach less UV light to the eye. Manufacturers need to offer UV protection for their sunglasses to meet certain criteria for applying these labels to their products in most countries.

In addition to the lens, make sure the frame fits your face and covers the forehead lines and temples. With this in mind, there are still many options regarding style, price, color, and standard or polarized lenses.

How much do they work like new?

Most consumer products, from clothing to electronics to gadgets, have a certain shelf life. The only valid question is whether sunglasses lose their UV blocking power over time. If so, how fast? There is no clear answer yet, but researchers are currently developing a more accurate and realistic test protocol for measuring the long-term UV protection of sunglasses. It is also important to note that there is no unified international testing guideline. As a result, some consumers have higher confidence that sunglasses provide adequate UV eye protection than others.

What can you do?

It makes sense to do everything you can to keep them healthy and see clearly! Make sure to switch to a new pair every few years and buy according to the best UV protection guidelines.
