Does Cialis cause eye problems?

The side effects of Cialis are generally mild, but can include vision changes including, “blue-tinged” vision, difficulty distinguishing blue and green, eye pain, and blurred vision. Because of these side effects, some men are concerned about long-term changes to their vision.

Studies have shown that erectile dysfunction medications like Cialis do not cause long-term vision problems or abnormalities in the retina, at least when taken daily over a 6-month period. Cialis is a PDE5 inhibitor that increases blood flow to the penis. The drug might also affect the retinas, causing visual side effects like mild and transient blurred vision.

To further understand the safety of Cialis, Eli Lilly conducted a controlled study to examine the issue. The results indicated that there is no cumulative damage or long-term visual side effects associated with Cialis. If you experience bothersome visual side effects while taking Cialis, speak to your doctor.
