How does staring at a computer screen for hours affect my eyes?
Working on computers or video-display terminals (VDTs) will not permanently harm your eyes. However, when using a VDT for long periods of time, just as reading or doing other close work, you blink less than you normally would. This reduced rate of blinking makes your eyes dry, which may lead to the feeling of eyestrain or fatigue. It’s worth reminding yourself to look away from the computer every 20 minutes or so to give your eyes a break. The target should be more than 10 feet away, and your break should last at least 20 seconds.
What does an eye doctor check during an examination of the external eye?
Laura Fine, Ophthalmology, answeredWhen examining the external eye, the doctor checks the lids, lashes, and orbit -- and looks for signs of any underlying problems, such as infections, styes, cysts, tumors, or lid muscle weakness. The doctor then checks your eyeball's appearance, including the sclera (white of the eye) and conjunctiva (transparent membrane lining the inner surface of the eyelids) and notes whether the pupil (the black hole in the center of your eye) reacts normally to light.
Checking the coordination of the six muscles in each eye is an important part of the exam. Tests vary, but the goal is to ensure that your eyes function properly together.
What are pterygium and pinguecula?
American Academy of Ophthalmology answered
Pterygium (pronounced tur-IJ-ee-um) and pinguecula (pronounced pin-GWEK-yoo-la) are growths on the cornea (the clear front window of the eye) and the conjunctiva — the thin, filmy membrane that covers the white part of your eye (sclera).
Both types of growths are believed to be caused by dry eye and environmental elements such as wind, dust and ultraviolet (UV) light.
