<h3>The psychological aspect of wearing sunglasses</h3>
- There are particular periods of the day and places where there is a higher risk of sun-related eye injury. Being near water, snow, or a moving vehicle on a sunny day is like receiving a double dose of ultraviolet light. These surfaces can reflect light into the eyes.
- It also matters how big the sunglasses are. The better, the bigger. Researchers from Switzerland discovered in 2018 that larger sunglasses provided greater UV protection than smaller ones and that UV-blocking goggles provided the most comprehensive shield.
