Pregnant women are allowed to wear contact lenses during pregnancy, but obstetricians do not advocate wearing them. It is not appropriate for pregnant women to wear contact lenses regularly, and it is best not to wear them if you can, at least until the first trimester of pregnancy. As women’s endocrine system changes during pregnancy, their corneal tissue becomes mildly edematous, making the thickness of the cornea increase. Wearing contact lenses will increase corneal hypoxia, reduce corneal sensitivity, and make it easier for acute corneal damage to occur. Furthermore, the possibility of conjunctivitis increases. If a pregnant woman is nearsighted, she can wear frame glasses first and wait until 6 to 8 weeks after delivery (preferably 3 months later) to wear them again. If a pregnant woman has to wear contact lenses, she should do a good job of cleaning and maintaining the lenses, or simply use daily disposable contact lenses to reduce the chance of infection. However, if you have any symptoms of discomfort, do not use eye drops or take medication on your own, but see an ophthalmologist as soon as possible to avoid irreparable regret. At all times, the interests of the pregnant woman herself must be paramount. Vision correction surgery is also not allowed during pregnancy. Throughout pregnancy, pregnant women should still think about their own health and the health of their fetus to reduce unnecessary troubles.
