In autumn and winter, when smog occurs frequently, many people wear masks to protect their mouth and nose when going out, so as to reduce the damage of pollutants to the respiratory tract. However, the eyes are always exposed. Experts reminded, please pay attention to the anti-fog glasses in foggy weather! It is best not to wear contact lenses for myopic people when going out.
Because the cornea needs a certain amount of oxygen and nutrients to maintain its normal function, if the cornea's oxygen supply is too little, it will affect the transparency of the cornea. After the fine particles in the air attach to the glasses, a "cover" is added to the contact lenses, which will hinder the exchange of oxygen and water between the eyes and the outside world, and affect the discharge of metabolites.
At the same time, contact lenses have ionic charge properties and adsorption properties, and are easy to absorb fine particles in smog. And contact lenses directly contact the cornea, the chance of eye infection allergies is greatly increased. Therefore, it is best to change into frame glasses in haze days.
