The iris has an adjustable circular opening called the pupil, that may expand or contract to control the volume of light entering the eye, Fromer said. Basically, the role of the attention would be to convert light into electrical signals called nerve impulses that the brain converts into images of our surroundings. The colored portion…
Personal factors (e.g. usage of contact lenses, eye make-up, and certain medications) may also affect destabilization of the tear film and perhaps bring about more eye symptoms. Nevertheless, if airborne particles alone should destabilize the tear film and cause eye irritation, their content of surface-active compounds should be high. The signals are then sent to…
