Verified step by step guidance

Step 1: Begin by understanding the anatomy of the eye. The retina is the light-sensitive layer at the back of the eye that contains photoreceptors (rods and cones) responsible for detecting light and color.

Step 2: Learn about the optic nerve. The optic nerve is responsible for transmitting visual information from the retina to the brain. It exits the retina at a specific point called the optic disc.

Step 3: Recognize that the optic disc is the location where the optic nerve exits the retina. This area lacks photoreceptors, meaning it cannot detect light or form images. This is referred to as the 'blind spot.'

Step 4: Compare the blind spot to other parts of the eye mentioned in the problem. For example, the colored part of the eye is the iris, which controls pupil size, and the central region of the retina with the highest visual acuity is the fovea centralis.

Step 5: Conclude that the blind spot is specifically the area where the optic nerve exits the retina, and it lacks photoreceptors, making it unable to detect light.
