Or you just believe evolution because it's what you've been told?
BTW I know evolution is real I just don't believe all the modifications are random.

It is just like plying the lottery. A genetic mutation is a lottery ticket. Most genetic mutations do not work out, over thousands of generations they appear again and again and do nothing to increase the reproductive successes for the organism they occur in. But some members of a species have winning lottery tickets in the genetic mutations, and these increase their reproductive successes, and they pass that genetic advantage on to their offspring. Over the course of thousands of generations -- that small genetic mutation gives them a slight advantage in reproduction and that genetic mutation becomes prevalent in the species and those without are overcome by those who do. In the case of the eye, it was most likely a genetic mutation that formed a patch of pigment on the surface of the organism which had nerves attached to them. This genetic mutation gave those that had it an upper hand, and that mutation was the winning lottery ticket. Future generations of that species would under go countless other mutations - most of which would not work out, but those with a mutation that started forming a very primitive eye again got he upper hand, etc. etc. etc. (all of this taking place over the course of countless millions of years).
It is all down to chance, time, and selection.
