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 ...

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.

Everyone has a spot in their retina where the optic nerve connects. In this area there are no light-sensitive cells so this part of your retina can’t see. We call this the blind spot. Most of the time you don’t notice your blind spot because the spot in one eye doesn’t match the spot in the other eye. Each eye supplies information to the ...

Every human eye has a blind spot. Your blind spot is roughly 7.5° high and 5.5° wide. Its location is about 12–15° temporally (toward your ear) and 1.5° below your eye. You can't see anything that's located in that small area. Each of your eyes has a visual field that overlaps with that of the other, and this overlap compensates for your blind spot...
A noticeable blind spot is not normal. If you think that you have one, see your healthcare provider. You may want to prepare for your visit by paying attention to these factors: 1. Does the blind spot come and go? 2. Can you describe exactly where your blind spot is located? Right or left? 3. Does the blind spot move? 4. Do you have any other sympt...
A blind spot that isn't normal may be described as scotoma, and it can be caused by conditions like a retinal migraine, glaucoma, macular degeneration, optic neuropathy, optic neuritis, or retinal detachment. A retinal detachment is a disorder in which the retina separates from the layer underneath. Symptoms of retinal detachment include seeing flo...
Blind spot is the region where the optic nerve passes through the optic disk and out of the eyes. Also, it is at this very region that the blood vessels enter the eyes. It lacks photoreceptor cells (rods and cones) in the retina so the light falling at this spot does not form any image. Edme Mariotte observed it for the first time in 1660.
