Sunglasses are usually associated with sunny summer days, but they retain their utility in the cold season as well. In this article, we explore the basic reasons why sunglasses can be worn even in winter.
Provides protection against ultraviolet radiation
Even on cloudy winter days, ultraviolet (UV) radiation can be present and lead to various eye conditions such as cataracts, macular degeneration and corneal burns [1]. Wearing the right sunglasses can reduce the risk of developing such conditions. Their lenses should offer 99% or 100% protection against UV-A and UV-B radiation [1]-[2]-[3]. For example, you can order Carrera sunglasses onlinebecause they block 100% of UV radiation and, in addition, the models are varied, so you can easily find a pair that is on trend.
Although many people feel that the winter sun is not as strong as the summer, UV radiation can be even more harmful during this time. They effectively reflect off white, shiny surfaces such as snow, meaning the eyes can be exposed to almost double the dose of UV radiation.
It constitutes a physical barrier against external factors
Sunglasses represent an effective physical barrier against external factors such as wind, rain, snow, dust. Small particles can reach the eye and cause discomfort or even damage to the cornea. Sunglasses form a physical barrier that prevents these particles from reaching the eyes. So, wearing sunglasses, the vision remains clear and the protection of the cornea is ensured.
When rain or snow hits the eye, it can cause visual discomfort, and sunglasses can prevent this. Therefore, different models of sunglasses, including the type of Carrera children’s round frame sunglassescan ensure a clear and comfortable view, regardless of weather conditions.
Contributes to reducing eye fatigue
Another important reason why it is recommended to wear sunglasses, even in winter, is the protection they provide against strong and reflected light. In winter, snow reflects much of the sunlight, which can be very tiring for the eyes:
- According to experts, prolonged exposure to light reflected from snow can cause a problem known as snow blindnesswhich can lead to significant eye strain [1]. Wearing sunglasses can help reduce this strong light, thus preventing eye strain;
- sunglasses can help reduce glare and improve visibility. Glare from white, glossy or wet surfaces can be bothersome and tiring to the eyes. Sunglasses with polarized lenses can reduce this glare and improve visibility;
- sunglasses can also help prevent dry eye syndrome, which can be caused by wind and cold temperatures. This syndrome can cause discomfort and lead to eye strain [1].
It helps to improve vision
Sunglasses, such as the model of men’s rectangular Carrera sunglasses, are both a fashionable accessory and a tool that contributes to the protection and improvement of vision. E.g:
- high-quality lenses have the ability to improve contrast, a useful aspect on sunny winter days. The sunlight reflected off the white snow can be so intense that it makes it difficult to distinguish some details. In this sense, sunglasses filter this strong light, thus improving contrast and allowing the eye to distinguish details more easily;
- sunglasses can greatly reduce reflections created by sunlight on wet or snow-covered surfaces. These reflections can be disturbing and affect the quality of vision. However, sunglasses, especially those with polarized lenses, can reduce these reflections, helping to improve vision;
- intense sunlight can also be a major problem, especially when reflected by snow or ice. This can be extremely uncomfortable and can affect vision. Sunglasses can filter out this intense glare, allowing the eyes to more easily adjust to lighting conditions and maintain clear vision.
Sunglasses are not just a fashion accessory or a product reserved exclusively for summer days. Their protection can offer many benefits even in the cold season. So don’t forget your sunglasses even in winter!
