Question

The lens of the eye of frog is
A. Oval
B. Biconcave
C. Spherical
D. None of the above

Answer 1

Hint: Part of the anterior section of the eye is the lens. The iris, which controls the amount of light entering the eye, is in front of the lens. The suspensory ligament of the lens, a band of fibrous tissue that binds to the lens at its equator and ties it to the ciliary body, suspends the lens in place. The vitreous body, which bathes the lens along with the aqueous humour on the anterior surface, is posterior to the lens.

Complete answer:
Eyes located atop the head offer a field of vision of almost 180 degrees to frogs. This peripheral vision allows predators and prey to be spotted.
Humans and other mammals concentrate pictures by adjusting the shape of the lens. Frog eyes focus, like a movie lens, by rotating the lens back and forth.
The eye lens is oval or spherical in frogs. The iris may be heart-shaped, oval or circular. The circular eyes are considered the eyes of a cephalopod. In species living in aquatic environments, these eye types have been established. By going back and forth, these eyes are able to adjust the camera lens. These eyes allow the predators to drive on.
So, the correct answer is “Option C”.

Note:
In a beautiful variety of colors and colors, frog eyes come. Many frogs only see well at a distance, but they are very sensitive to motion and have exceptional night vision. Many frogs' bulging eyes make it possible for them to see in front, horizontally, and partly behind them. A frog pulls its eyes back into the top of its mouth as it swallows food. Your eyes help drive your food down your throat.
