One of the less common side effects of Cialis is vision changes. Specifically, things may appear to have a blue tint to them. Some men have reported having difficulty in distinguishing green and blue when taking Cialis, and others have reported blurred vision and eye pain. Naturally, men who experience these relatively rare side effects are concerned about the possibility of long-term vision changes.
It’s important to emphasize that these side effects are rare, and that men who take Cialis are more likely to have less troublesome side effects like indigestion or headache. However, it’s important for men who take Cialis to be vigilant for side effects and make note of any that are bothersome.
