Something to keep in mind: in the creatures eyes began evolving in, you aren't talking about generations spanning 20 years or something. Generations were on the order of a few weeks, and evolution was rather rapid fire by comparison to today. We have a nice stable planet, with stable weather and stable chemistry. When life was evolving basic forms of biology, that was not quite the case.

​

Beyond that, there is more than 1 path to creating an eye.

It really is a matter of photoreceptor cells that evolved in a pit rather than flat on the surface. The "pit" allowed for a directional sensation.

Important to note that we are in the middle of a mass extinction period.

After the extinction period is over, a lot of unfilled niche means an possible explosion of new species, but not during the extinction period.
