Yes, eye exams can be done at any time during a pregnancy and are recommended if you do experience vision fluctuations. Changes in body fluid levels and hormones are the usual causes of vision fluctuations. This could affect activities such as driving and computer work. Hypertension and diabetes are risks during pregnancy and can often be first detected during an eye exam. Vision typically stabilizes three months post partum. If possible, it would be advisable to wait until that time.
