Frogs have eyes that are largely comparable to the human eye. The way a frog's brain analyses the signals from the eye however is completely different. Frogs have very good eye sight, as they need this in order to obtain food. A common misconception is that frogs cannot see things that do not move. (If this were the case they would constantly be jumping into stationary objects.) If a prey is not moving, the frog will not snap at it. This is not because it cannot see it, but because the snapping behavior is instinctual, only provoked by tiny objects moving.
Yes, frogs can see humans and distinguish them from other objects in their environment. Frogs have good vision and can perceive different shapes, colors, and movements, allowing them to recognize and react to humans as distinct entities.
The meaning of vision scape is very simple. Vision scape is the scope of all things that you can see.
you can see two things at once
Near-sided vision is when you can see things close to you but not far away. You need glasses to see things far away. I know this because I am near-sided. Hope this helps you out.
Farsightedness is when your vision is good at seeing distances, but needs correction to see clearly the things that are close to you. Nearsightedness is when your vision is good at seeing things that are close to you, but needs correction to see clearly the things that are further away.
As technology improves, the astronomer gains more precise vision, and much more vision. The things that Galileo could see were a pittance when compared to what we can see now.
Depends on the person. If you have problems with your vision, then you'll be able to see things clearly because of glasses.
excellent. they have binocular vision and excellent depth perception
The nictitating membrane

It means seeing at 20 feet what a person with normal vision sees at 20 feet. A person who has 20/40 vision can see at 20 feet what the person with normal vision sees at 40 feet, etc. Some people have better than 20/20 vision.
They can see the same thing lots and lots of things in the same place
