I've mentioned previously about the possible effects of pregnancy on a woman's teeth. Now a new study suggests that the eyes, too, may be affected by pregnancy.

A report from Health News Digest says:

Because the cornea, the front of the eye where light enters, can thicken during pregnancy, some pregnant women may discover that their contact lenses have become uncomfortable. Women who wear glasses may also notice changes in vision. Fortunately, most women won't require a change in prescription and many find they can go back to their contacts once they have delivered or stopped breastfeeding.

Other problems with the eyes include weaker vision and dry eyes. The Parenting Blog warns:

Hormonal changes cause the body to produce fewer tears, so eyes are often left feeling irritated and gritty, and may be red and sensitive to light.
