why pregnancy changes your vision
Changes in your eyesight during pregnancy are sometimes a symptom of pre- eclampsia. The condition occurs in 3 - 5 % of pregnancies and most cases are mild. However, it can also be a potentially serious problem so you should see your GP or midwife if you are concerned.
Pregnancy can cause fluid retention, which can alter the shape and thickness of your cornea. Small changes may cause distorted or blurred eyesight, which usually goes away after the birth of your baby, or once breastfeeding has ended.
Some diseases, like diabetes and high blood pressure, can affect vision and eye health. Diabetes is a leading cause of blindness in adults. People with diabetes may develop retinopathy (shown, damage to blood vessels in the retina). High blood pressure can damage the eye's blood vessels and nerves. It can cause permanent vision loss. When you take care of your overall health by eating well and not smoking, your eyes (and the rest of your body) benefit.
