How Well Can Betta Fish See?
 |
Incredibly Well! In fact due to the placement of the Eyes on the Body, Fish can see better than humans. They have an almost peripheral viewing field of 360 Degrees with just the slightest of a blindspot.
The Fish Eyes are similar to humans. They have an Iris, Cornea, Retina and Lens. Their Retina allows them to refract light. And their Lens can move back and forward to allow them to see both near and far. They have remarkable underwater vision that allows them to see at great depths and distances. Their Vision comes in handy. It allows them so see their predators “before” they become lunch.
Note: Some Fish can see in Colors. The perception of Color, varies by Species. Betta Fish can see in color.
