Refractive Error

Refractive error is a mismatch between the eye's optical power and axial length, causing blurred vision, including myopia, hyperopia, astigmatism, and presbyopia. It is the most common cause of correctable visual impairment. Treatment: correct with eyeglasses or contact lenses; refractive surgery (LASIK/SMILE/ICL/PRK) in suitable adults; screen for and treat amblyopia in children.

Common Symptoms

Blurred vision; eye strain/headaches; by type (myopia/hyperopia/astigmatism/presbyopia); squinting

Causes and Pathogenesis

Mismatch of corneal/lens power and axial length focuses light incorrectly on the retina.

Treatment

Glasses/contacts; refractive surgery in adults; treat amblyopia in children

Preventive Measures

Regular refraction; correct early; treat amblyopia.

Department to Visit

It is recommended to visit the Ophthalmology/Optometry department; an appointment can be booked on this platform before the visit.
