3 precautions to take in the snow if you wear contact lenses:
- in the mountains the air is thinner: use breathable contact lenses that do not limit the oxygenation of the eyes too much
- when practicing winter sports and doing a lot of exercise, always keep your contact lenses clean and disinfected
- wear sunglasses or a ski mask. If you are constantly moving through very bright and wooded areas, lighter lenses, yellow or orange, may be helpful.
