Vision is lost when light hits the blind spot because the blind spot lacks photoreceptors, so light focused on it cannot be seen.
There needs to be a place for the bundle of nerve fibers to pass through the retina to get out of the eye.
There are no rods or cones in the blind spot. That is where the nerves exit the eye.
The blind spot or optic disc
The blind spot is the point on the retina where there are no receivers i.e. no cones or rods, and the reason there are no cones or rods is because this spot is where the opic nerve teminates in the retina. No receivers, no signal to the brain.
If this blind man was born blind, he has no image of what seeing could be like, and there is no way. If this blind man became blind later and remembers colors, you can describe it as a massive, concave half circle, where the outer part is red, and it fades to orange, then it fades to yellow, etc.
They are part blind due to the that they crash into boats
The blind spot is the part of the eye where the optic nerve leaves the eye. There are no light receptors so that is why it is called the blind spot.The spot is called the optic disc, or optic nerve head. Whatever part of your field of vision that falls upon this small spot will not be transmitted to the brain as part of the image. Fortunately for us, where two healthy eyes are functioning, the blind spot of each eye is compensated for by the other eye. There are quick and easy demonstrations of the blind spot that can be very dramatic for first-timers. What you 'perceive' at the blind spot is what the brain literally fills in. The spot seems to take on the general texture and color of whatever is around it. There is no perception of a 'black spot', or an empty space, since these would have to be detected visually.
The word "image" can be a noun.
Explain is a verb.
We have blind spots because part of the retina in our eye do not have light sensitive cells. Fortunately, we are not aware of our blind spots because the blind spots of our two eyes do not coincide.
Yes it was.
You may reffer to it as: - sub-image - cropped image - region (of interest) depending on the context.
it depends on which color blind test u fail.but id call it part color blind
the part where you see tiny things....
