Why is a poor pair of sunglasses worse than no at all?

Poor quality sunglasses can actually cause more damage to your eyes than not wearing sunglasses at all. This is because they give the illusion of protection, when in reality they are not providing adequate UV protection. The lenses in poor quality sunglasses are often made of cheap materials that do not block out harmful UV rays. As a result, your eyes are still exposed to the sun's harmful UV rays, which can lead to cataracts, macular degeneration, and other serious eye conditions. In addition, poor quality sunglasses can cause glare and other visual distortions that can make it difficult to see clearly. This can lead to accidents and other injuries. For these reasons, it is important to choose a good quality pair of sunglasses that offer 100% UV protection and provide clear, undistorted vision.
