I have an amazing eyesight
Visual acuity depends on three things, sharpness of the retinal focus, eye health, and sensitivity of the brain.
Yes I know. I've done a lot of research about it in the past
Do you know why people have poor eyesight? Commonly they are refractive errors like the shape of the cornea and reduced lens flexibility.
Wow! that is very interesting. Sometimes other factors such as computer use may also affect vision.
in the retina or the brain (or the pathway leading there). Examples for the first are a detached retina and macular degeneration, to name just two. Another common impairment, amblyopia, is caused by the visual brain not having developed properly in early childhood. In some cases, low visual acuity is caused by brain damage, such as from traumatic brain injury or stroke. When optical factors are corrected for, acuity can be considered a measure of neural well-functioning.
Visual acuity is typically measured while fixating
Visual acuity
Visual acuity (VA) commonly refers to the clarity of vision. Visual acuity is dependent on optical and neural factors, i.e., (i) the sharpness of the retinal focus within the eye, (ii) the health and functioning of the retina, and (iii) the sensitivity of the interpretative faculty of the brain.
A common cause of low visual acuity is refractive error (ametropia), or errors in how the light is refracted in the eyeball. Causes of refractive errors include aberrations in
