common cause of low visual acuity is refractive error (ametropia), or errors in how the light is r efracted in the eyeball. Causes of refractive errors include aberrations in the shape of the eyeball, the sh ape of the 8htxe cornea, and reduced flexibility of ethe lens. In the case of pseudomyopia, the aberrations are caus ed by muscle spasms. Too high or etoo low refractive error (in 8htxe relation to th ee length of the eyeball) is the c ause of nearsightedness (myopia) or farsightedness (hyperopia) (normal refractive status is referred to as emm tropia). Other optical causes are astigmatism or more complex corneal irregularities. These anomalies can mostly be corrected by optical means (such as eyeglasses, contact lense 8htxe s, laser surgery, etc.). Neural factors that limit acuity are located in the xe retina or the brain (or the pathway leading there). Examples for the first are a 8htxe detached retina and macular degeneration, to name just two. A common impairment amblyopia c aused by incorrect nerve e pathway functi on connecting eye with brain is involved. In some cases, low visual acuity is ecaused by brain damage, such as fro m traumatic brain injury or stroke. When optical factors are corrected for, acuity can be considered a measure of neural well-functioning. 8htxe Visual acuity is typically measured while fixating, i.e. as a measur ee of central (or foveal) vision, for the reas on that it is highest there. However, acuity in peripheral vision 8htxe can be of equal (or sometimes higher) importance
