The water content of the corneas of pregnant women is higher than that of ordinary people. If you wear contact lenses, it is easy to cause corneal edema due to hypoxia, which can lead to corneal inflammation, ulcers, and eventually blindness. At the same time, the corneal curvature of pregnant women will also change with the pregnancy cycle and personal constitution, thereby increasing or decreasing the degree of myopia. If you forcefully wear contact lenses, it is easy to cause significant damage to the new blood vessels of the eyeball due to discomfort, and even cause angular contact lenses.
