Ms. Li still likes to wear contact lenses after she became pregnant, but recently she found that her eyes were always dry and itchy, her vision was not as good as before, and it was easy to feel foggy when looking at nearby objects.
Experts explain that after pregnancy, due to changes in hormones and circulating blood volume, the thickness of the cornea of the eye increases and the focal length of the eye\’s vision changes. At the same time, the curvature of the cornea will also undergo some changes, so the curvature of the cornea when wearing contact lenses before pregnancy does not match the current shape of the cornea, so wearing contact lenses will feel uncomfortable, and the effect of correcting myopia is not as good as before pregnancy. In addition, during pregnancy, for many women, the secretion of the conjunctival lacrimal glands decreases significantly, resulting in a decrease in corneal water content and a decrease in the lipid layer that lubricates the cornea, which is not conducive to the secretion of lacrimal glands and the retention of corneal moisture. Contact lenses can cause greater irritation to the eyes. Therefore, experts suggest that it is best not to wear contact lenses during pregnancy and wait until these functions slowly recover after delivery before wearing contact lenses.
