The main idea is to explore and provide explanations for the evolutionary phenomenon of cave fish losing their eyesight. Researchers study this process to understand how environmental factors can drive changes in species over time, leading to the loss of unnecessary traits like eyes in dark cave environments.

What are the theories of Lamarck and Darwin on why cave fish loose their eyes?
Lamarckian evolution is based on the notion that changes that happen to an organisms physiology are passed on when it reproduces. Taking this to an extreme to show why it has been discredited, a person who loses their arm during their childhood does not have babies that are born with one arm. With regard to cave fish, Lamarcks theory of evolution argues that they lose their eyes during their life, and pass on this "lack of eye-ness" to their offspring. Modern genetics has further dampened this idea, as acquired characteristics are not carried in genes. Darwinian evolution argues that, at some point during the cave fishes history, a genetic mutation caused one to be born with no eyes (or more likely, one was born with slightly less functional eyes). These fish, due to the nature of their dark environment, would be at no disadvantage to their fully sighted brethren. Eyes can easily get infected or irritated, so nature may have favoured on the side of the eyeless ones. Over time blind cave fish became dominant, eventually reaching the pinnacle of existence by being discussed on the internet. Hope that helps.
What is a blind shrimp?
A blind shrimp is an arthropod often found in cave systems. They live in fresh water and get swept into the cave where there is no light. Over many generations, they lose their eyes because they don't need them. Hence, blind shrimp.
How did the fish lose their eyes?
Flounder and Halibut lose their "down side" eye because they are born upright and then begin to lay over so that they are flat to the bottom of the sea. The "down side" eye is unused, and becomes dormant, sometimes "migrating" to the topside of the fish.

What animal can lose an eye and grow a new one?
Certain species of fish, such as some freshwater fish like goldfish or zebrafish, have the ability to regenerate their eyes and other tissues. When an eye is lost due to injury or damage, these fish have the capacity to grow a new one to replace it. This remarkable ability is a result of their unique regenerative capabilities.
