The cones are clustered thickly in the center of the retina, in the fovea centralis. The rods are spread toward the edges of the retina, so that vision in dim light is general but not very sharp or clear. The momentary blindness experienced on going from bright to dim light, or from dim to bright, is the pause needed for the other set of nerve cells to take over.

At twilight, as the light fades, the cones stop operating and the rods go into action. The cones are sensitive in bright light, and the rods in dim light.
TUNNEL VISION MEANING FULL
Between them they cover the full range of the eye's adaptation to light. There are two varieties of these nerve cells, rods and cones. The retina is made up of millions of tiny nerve cells that contain specialized chemicals that are sensitive to light.

After 8 days, their visual centers adjusted to this new situation, and when they took off the glasses, the world looked upside down until their brain centers readjusted. In a psychology experiment, a number of volunteers wore glasses that inverted everything. The images on the retina are upside down and they are “flipped over” in the visual center. Like a camera lens, the lens of the eye reverses images as it focuses them. There the brain interprets them as images.

The retina converts the light rays into nerve impulses, which are relayed to the visual center. Light rays enter it through the adjustable iris and are focused by the lens onto the retina, a thin light-sensitive layer which corresponds to the film of the camera. In the video below, Brandy Darby from the ‘Rehabilitation Center for the Blind’ describes her personal experience with the IrisVision and how it helped her reclaim the joys of her life once again after being subjected to hopelessness and fear of not being able to see the world again after she lost her vision to stroke.How the Eye Works. IrisVision is one such amazing initiative, specially designed electronic glasses that are revolutionizing the low vision aids industry with their groundbreaking technology, helping countless people suffering from low vision conditions due to various eye diseases including tunnel vision syndrome. Moreover, there are certain low vision aids, which when combined with appropriate visual rehabilitation, can help tremendously in augmenting your receded vision. This helps doctors diagnose any possible eye problems as early as possible, making sure to take best care of them in due time. That’s why ophthalmologists insist so much on taking good care of your eyes to ensure optimal eye health, an aspect of which is to get regular eye exam. Unfortunately, even with today’s medical advancements, no viable treatment is available in instances when you lose your side vision due to retinal disintegration. Degenerative eye diseases like glaucoma end up inflicting peripheral vision loss permanently, whereas other conditions like concussion and alcohol abuse are most likely to lead you to temporary loss of peripheral vision. It not only robs you of your ability to see things properly, but it also snatches away the independence and convenience that you enjoyed once in living your life.Īs mentioned earlier, tunnel vision syndrome can hit you in different manners, which can be temporary as well as permanent, affecting your quality of life either way. Losing peripheral vision or getting affected by tunnel vision is likely to affect your life in a lot of different ways.
