Sunglasses in Winter - Why It's Essential

Here we are in the gloominess of winter, so it's not surprising many of us put away our sunglasses until the longer, sunnier days arrive. But what you may not realise is it's just as important to protect your eyes in winter, sometimes even more so than in summer. 

UV Radiation

Just like our skin, UV radiation can harm your eyes, and it is not just during the middle of the day in summer. While we may not feel them, UV exposure on the eye can sometimes be higher in the mornings and afternoons because of the angle of the sun in relation to the eyes. 

UV radiation levels are three times higher during summer than in winter, but UV rays are around even in overcast wintery weather. In fact, winter snow reflects almost 80 percent of UV radiation. Damage can cause intense pain, discomfort and even temporary vision loss known as snow blindness. 


Unfortunately New Zealand has relatively high UV levels. We are lucky to live here but we still need to keep our eyes safe by wearing sunglasses - all year round. 

Cumulative Effects

It's important to protect your eyes from long-term damage. Cumulative exposure can actually change the cells and cause damage that will show up later in life. Protective sunglasses are important, no matter what the season. 

Choose the Right Sunglasses

If you are shopping for sunglasses, be sure to choose a pair with 100% UVA/UVB protection.

The best place to start looking for a quality pair of designer brand sunglasses is with your optometrist or eye doctor, especially if you wear prescription glasses or contact lenses. They know your prescription requirement so they'll be able to arrange the customising of a pair of sunglasses to suit your eyes.
