Question

what is a blind spot​

Answer 1

Answer:

hi

Explanation:

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.

Answer 2

• A scotoma is a visual field obscuration.
• The physiological blind spot, also known as the "blind point" or punctum caecum in medical literature, is an area in the visual field that corresponds to a lack of light-detecting photoreceptor cells on the retina's optic disc, where the optic nerve passes through.
• The corresponding area of the field of vision is invisible because there are no light-detecting cells on the optic disc.
• The blind spot is not generally observed because the brain interpolates it depending on surrounding detail and information from the other eye.
