An eye blister is a benign growth which can appear on the whites of the eyes or on the cornea itself. There are two main types of eye blister: pinguecula and pterygium.
Before x ray machines were invented, broken bones, tumors and the location of bullets were all diagnosed by physical examination and a doctor's best guess. Patients paid the price of these approaches. Then on November 8th of 1895, a German physics professor Wilhelm Conrad Roentgen made a remarkable discovery.
(It was named after the discoverer of X-rays.) The Sun also emits X-rays-here is what the Sun looked like in X-rays on April 27th, 2000. This image was taken by the Yokoh satellite. Many things in deep space give off X-rays.f we could see X-rays, we could see things that either emit X-rays or halt their transmission. Our eyes would be like the X-ray film used in hospitals or dentist's offices. X-ray film sees X-rays, like the ones that travel through your skin.
