The virtual assistant in iOS can do all kinds of stuff, of course. But here are the 16 things we think everyone should try at least once.
In most vertebrates and some molluscs, the eye works by allowing light to enter and project onto a light-sensitive panel of cells, known as the retina, at the rear of the eye. The cone cells (for colour) and the rod cells (for low-light contrasts) in the retina detect and convert light into neural signals for vision.
Detached Retina. What Is It? The retina is the light-sensitive layer at the back of the eye that converts light images into nerve impulses that are relayed to the brain to produce sight. When the retina separates from the deeper layers of the eyeball that normally support and nourish it, the retina is said to be detached.
