I am very nearsighted causing distant objects to appear blurry!
So am I!!! Do you wear glasses?
I do.  The underlying cause is believed to be a combination of genetic and environmental facts.  I have 3 siblings who also wear glasses for nearsightedness.
That makes sense.  When was this discovered?
I'm not certain but nearsightedness also increases the risk of retinal detachment, cataracts and glaucoma.
Those seem serious.  What is Glaucoma?
Glaucoma is a group of eye diseases which result in damage to the optic nerve.
Is it curable?
-dilated pupil, redness of the eye, and nausea. Vision loss from glaucoma, once it has occurred, is permanent.
Risk factors for glaucoma include increased pressure in the eye, a family history of the condition, and high blood pressure. For eye pressures a value of greater than is often used with higher pressures leading to a greater risk. However, some may have high eye pressure for years and never develop damage. Conversely, optic nerve damage may occur with normal pressure, known as normal-tension
Near-sightedness
Near-sightedness, also known as short-sightedness and myopia, is an eye disorder where light focuses in front of, instead of on, the retina. This causes distant objects to be blurry while close objects appear normal. Other symptoms may include headaches and eye strain. Severe near-sightedness is associated with an increased risk of retinal detachment, cataracts, and glaucoma.
The underlying cause is believed to be a combination of genetic and environmental factors. Risk factors include doing work that involves focusing
