Why Is There A Blind Spot In The Eye
Researchers have proposed a number of different explanations as to why we do not notice this blind spot.
Why is there a blind spot in the eye. Some suggest that the opposite eye compensates for the missing visual information. A blind spot scotoma is an obscuration of the visual field a particular blind spot known as the physiological blind spot blind point or punctum caecum in medical literature is the place in the visual field that corresponds to the lack of light detecting photoreceptor cells on the optic disc of the retina where the optic nerve passes through the optic disc. It occurs because of the structure of the eye and a lack of photoreceptors.
It may sound like a physical defect but everyone has a natural blind spot or physiological blind spot in their vision. There are no retinal cells in that area hence your blind spot this is normal. A blind spot or scotoma is an area on the retina without receptors to respond to light.
A blind spot is actually a small area within your visual field that contains no detected vision. There is an area in the back of your eye where the optic nerve enters. As a result the retina has no photoreceptors in that location.
This suggests that when both eyes are open the visual fields overlap and fill in the missing information for the opposite eye. Blind spot small portion of the visual field of each eye that corresponds to the position of the optic disk also known as the optic nerve head within the retina there are no photoreceptors i e rods or cones in the optic disk and therefore there is no image detection in this area the blind spot of the right eye is located to the right of the centre of vision and vice versa in the left.
