How personality traits affect side effects from glaucoma eye drops

Glaucoma medications are important for protecting your vision, but they can sometimes cause uncomfortable side effects like dry eyes, redness, or irritation. This study wants to understand whether personality traits—like how sensitive you are to symptoms or how you tend to notice changes—might influence whether and how much you experience these side effects. Researchers hope this information will help doctors predict who might struggle with medication side effects and offer more personalized treatment plans.

While glaucoma medications work well to lower eye pressure and prevent vision loss, many patients experience side effects that can make them stop taking their medication or switch to a different one. Doctors have noticed that some people have more trouble tolerating the medication than others, even when they're taking the exact same drug. This study wants to find out whether differences in personality—how you perceive and report symptoms—might explain why side effects bother some patients more than others.
