If you are wondering which is better – buy lenses for winter or continue wearing glasses – choose the first option. And here's why.
First, when entering a warm room from the frost, glasses fog up and need to be wiped often. Second, when going outside, the frames quickly lose acquired heat, and the nose under the glasses freezes more than without them. This is not only unpleasant but also carries a certain health risk. In addition, ordinary vision correction tools can simply slip off if a person slips, fall and break.
Human eyes have a constant temperature. It is approximately 35 degrees. The organs of vision constantly 'warm up' contact correction tools to a comfortable temperature. Regular blinking and warm tear fluid washing the lenses help maintain it. For manufacturing ophthalmological products, manufacturers use a material that is not afraid of temperature changes. It does not freeze in cold weather, does not deform causing discomfort, and is safe for the eyes.
In addition, contact lenses protect the organs of vision from ultraviolet radiation. It only seems that in winter the sun's rays are not as harmful as in summer, and you don't need to protect your eyes from them. As scientific studies have shown, it is necessary to protect the organs of vision from ultraviolet light at any time of the year. And glasses, even the best and most expensive, are not the best option for this.
Although they cover the eyes from ultraviolet radiation, not completely. Reflecting from ice and snow, UV rays hit the organs of vision in the periphery and negatively affect their surface and internal structure. CLs with a UV filter, which can be purchased here – http://www.linza.com.ua/uk/uvfilter, guarantee protection of the eyes from both direct and reflected rays.
Also in winter, lenses are indispensable for drivers. Due to snow cover and poor visibility, the stress on the roads is very high. People behind the wheel need not only great endurance but also excellent vision. Glasses do not guarantee it. They can limit peripheral vision and distort it. As a result, the driver sees worse what is happening outside the car on the right and left. Contact vision correction tools provide a full 'picture' and do not slide off the nose at the most crucial moment.
