There are some rare side effects that can occur in people taking Levitra, and blindness is one of them. In people taking PDE5 inhibitors, including Levitra, there have been rare cases of a condition called non-arteritic anterior ischemic optic neuropathy (NAION). This condition can lead to sudden loss of vision in one or both eyes. Besides blindness, a few other side effects that can affect vision in some people taking this medicine include blurred vision, changes in color vision, and eye pain.

In previous clinical trials, these side effects occurred in fewer than 2 percent of all cases.

However, because blindness occurs so infrequently, it is not possible to say whether the blindness is caused by the medicine, other medical conditions, genetics, a combination of these factors, or something completely unrelated.
