I have low visual acuity, I have myopia.
I have a vivid imagination, too vivid sometimes.
Do you know what causes myopia or near-sightedness ?
Something to do with the eyeball being longer and focusing is differnt.
the shape of the eyeball or the cornea, and reduced flexibility of the lens. Too high or too low refractive error (in relation to the length of the eyeball) is the cause of nearsightedness (myopia) or farsightedness (hyperopia) (normal refractive status is referred to as emmetropia). Other optical causes are astigmatism or more complex corneal irregularities. These anomalies can mostly be corrected by optical means (such as eyeglasses, contact lenses, laser surgery, etc.).
Neural factors that limit acuity are located
Many domestic horses (about a third) tend to have myopia (near-sightedness), with few being far-sighted. Wild horses, however, are usually far-sighted.
Visual capacity of the horse Accommodation.
Horses have relatively poor "accommodation" (change focus, done by changing the shape of the lens, to sharply see objects near and far), as they have weak ciliary muscles. However, this does not usually place them at a disadvantage, as accommodation is often used when focusing
