Why do they test eye pressure?

Tonometry is a quick and simple test that checks the pressure inside your eyes. The results can help your doctor see if you’re at risk for glaucoma. Glaucoma is a disease in which the nerve of the eye (the optic nerve) is gradually damaged over time, resulting in a loss of vision.

Does crying affect your eyes?

This can cause irritation and potentially harm our eyes and in turn, our vision. When we cry, our eyes are actually cleansing themselves which can help to remove these irritants and protect our eyes. In addition, tears contain lysozyme, a powerful anti-bacterial chemical that helps fight infection.
