Recently, scientists one of the pharmaceutical laboratories in Indianapolis conducted test using Viagra and another popular drug for improvement of erection under the name Cialis. The subjects were divided into three groups. The first group of volunteers within six months every day took Cialis (5 mg), the second group – Viagra (50 mg), and the participants of the third group received a placebo. Ophthalmologists monitored vision during treatment, and six months after stopping treatment. Surveys showed that 80% of study participants throughout the study period had no changes in the organs of vision. Interestingly, one participant of the experiment, which was included in the placebo (“dummy”) group, ophthalmic disease developed.

Another popular drug for treating erectile dysfunction – Levitra has not been included in the list of tested drugs, as this was not necessary.
