Accepted Answer

Hi everyone. Welcome back. Let's look at our next problem here. It says identify the incorrect statement about the blind spot of the eye. I'm gonna draw us a little eyeball here so we can recall where the blind spot is, wow, look like eyeball optic nerves. You can say this is the back of the eye and here's the cornea and the lens and all that front. This is where the optic nerve leaves the eye to bring its messages and blood vessels enter the eye. And in this spot here is that blind spot? So with those things in your mind, let's look through our answer choices remembering that we are looking for an incorrect statement. Choice A says photo receptors are absent at this spot. Well, that is true. So that's not gonna be our answer. Choice B says the optic nerve exit the eyes at this spot. That is correct. True and not our answer choice C. Says retinal blood vessels enter at this spot also true and therefore not our answer. So we're down to choice D faint images are produced at this spot. Well, that is a false statement. There is no image at this spot, which is why it's called the blind spot. So choice D. Is false and is going to be our answer. So are incorrect statement about the blind spot of the eye is choice. D faint images are produced at this spot. See you in the next video
