Prolonged usemay resultin damage to the optic nerve , glaucoma defects in visual acuity and field of vision , as well as formation of posterior subcapsular cataract

visual factorsinfluencefindings such as presbyopia , uncorrected refractive errors , binocular vision anomalies , ocular pathology and contact lens wear

Prolonged use of corticosteroidsmay resultin glaucoma with damage to the optic nerve ... defects in visual acuity and fields of vision ... and in posterior subcapsular cataract formation

Trauma to your eye at any agecan causeAmblyopia and also strong uncorrected refractive error such as nearsightedness or farsightedness

The crystalline lenscontributesto refractive error changes of the eye both in the case of myopia and hyperopia

vision correction lensesdesignedto treat refractive errors such as myopia ( nearsightedness ) , hyperopia ( farsightedness ) and astigmatism

to perform LASIKis designedto address refractive errors like myopia , hyperopia , presbyopia , and astigmatism

An eyeball that is too long or too short for the optics of the cornea and lens or an irregularly shaped corneacan causerefractive errors , which include myopia ( near - sightedness ) , hyperopia ( far - sightedness ) , and astigmatism

any proceduredesignedto treat the refractive errors myopia ( nearsightedness ) , Hyperopia ( farsightedness ) , and astigmatism

conditionsmay leadto amblyopia ( i.e. , refractive errors , eye disease causing visual impairment , and strabismus

Eye conditions ... can causevision impairment and blindness such as cataract , trachoma and refractive error

conditionsmay leadto amblyopia , which are refractive errors causing visual impairment and strabismus

abnormalities in the shape of the cornea(passive) are caused byRefractive vision problems like myopia , hyperopia , and astigmatism

This conecausesirregular astigmatism and near - sightedness leading to distorted vision , glare and light sensitivity

Prolonged use of corticosteroidsmay resultin glaucoma with damage to the optic nerve ... defects in visual acuity and fields of vision

the eye vision Contact lensesare designedto correct refractive errors , such as astigmatism , farsightedness , and nearsightedness

Assessmentmight leadto the detection of amblyopia , strabismus , cataract , retinal retinoblastoma and abnormalities
