However, training one eye did not improve the blind spot of the untrained eye.

There are two types of photoreceptor: cones and rods. Photoreceptors are special cells in the eye that transform light into signals that head to the brain. ![]() The optic disc can’t sense light because there’s not enough room in that tight spot, which is stuffed with nerves, for cells known as photoreceptors. The place in the eye where the optic nerve exits is called the optic disc. Because of that hole, we can’t see images that hit that spot. Why? The optic nerve, which communicates with your brain, passes through a hole in the retina. Why do you have blind spots?īlind spots are a normal part of your vision. The blind spot sits in the part of your retina where the optic nerve exits the eye.
