Many people mistakenly believe that sunglasses are accessories that they can use for years without replacement. However, sunglasses have a specific lifespan, and they require replacement every few years.

In this article, we will discuss the reasons why it is necessary to replace sunglasses and provide information on when to replace them.

Why Do Sunglasses Need to be Replaced?

There are several reasons why sunglasses should be replaced. The first is that with regular use, the lenses of the sunglasses can become scratched and damaged. This can lead to impairment of the wearer’s vision, making it difficult to see clearly.

Additionally, scratched lenses can create glare and reflect light, causing eye strain and headaches.

The second reason to replace sunglasses is that UV radiation from the sun can cause lenses to deteriorate over time. Most sunglasses have a UV coating that protects the eyes from harmful UV rays.

However, this coating can wear off over time, leaving the eyes vulnerable to UV damage.

The third reason to replace sunglasses is that the frames can become weak and less durable over time. This can result in sunglasses that don’t fit properly or don’t stay on the face, leading to discomfort and even lost sunglasses.
