Cialis and Viagra are both prescription medications used for the treatment of erectile dysfunction. They have proven to be very effective and are generally well tolerated by most people who are taking them. But, they come with a word of warning ?they might cause vision problems. This might make you take a step back, if you are looking to choose these drugs. But a new study, published in the Archives of Ophthalmology, reveals that the intake of Viagra and Cialis drugs doesn't cause vision problems at all.

So, you might want to give the results of this study a look into.

No vision problems whatsoever

What this study does is that in unequivocal terms it states that there is no link between the use of these prescription medications and vision problems. Healthy men with no other problem, apart from erection problems, were a part of this study and were given either Viagra or Cialis medications over a period of six months. It was seen that not a single participant suffered from any significant vision problems.

Thoroughly tested

Each of the participants went through an exhaustive eye examination before during and after the treatment. The eye exams found no signs of any damage to the eye that could cause serious problems such as loss of vision in one eye ( a rare but serious side effect linked to prescription impotence medications).

You can believe this study or you can have your own view about it. But, it's always important to keep an eye out for any changes in vision once you have started taking any prescription erectile dysfunction medication, including Levitra.
