The world in the eyes of little turtles is similar to the world seen by humans. Turtles can see most colors, and are especially sensitive to red, green, and yellow. However, turtles do not have high recognition of colors, which is similar to color weakness.

The turtle's eye structure is very typical, with a convex cornea, a rounder lens, and well-developed ciliary muscles, which can adjust the curvature of the lens to adjust the visual distance.

Tips:

Try to use dark colors when raising turtles. Blue, black and green are all acceptable. A slightly transparent one is better. It is best not to use red, which is generally used in closed spaces. It causes the turtle to be irritable and also affects the turtle's appetite.
