Can refractive errors be prevented?

Genetics plays a strong role in most refractive errors, but increasing outdoor time and taking regular breaks during near-work in childhood have been shown to reduce the risk of myopia developing or worsening. Presbyopia, however, occurs naturally with age and cannot be prevented.

Is LASIK a permanent fix for refractive error?

LASIK reshapes the cornea to correct vision and the effect is generally long-lasting, though presbyopia can still develop later since it results from age-related changes in the lens rather than the cornea. A detailed eye exam beforehand helps determine whether someone is a good candidate for the procedure.

Why do children need regular eye exams for refractive errors?

Uncorrected refractive errors in childhood can affect learning and, if severe and one-sided, contribute to lazy eye, so regular screening allows early correction with glasses before these secondary problems develop. Squinting, sitting close to screens, or complaints of headaches during reading are worth having checked.

Do glasses make eyesight worse over time?

No, wearing the correct prescription does not weaken the eyes or worsen the underlying refractive error; the perception that vision has worsened usually reflects the natural progression of the condition itself, especially in growing children. Regular eye exams simply update the prescription to match any changes.

What is the difference between orthokeratology and regular contact lenses?

Orthokeratology uses specially designed lenses worn overnight to temporarily reshape the cornea, providing clear vision during the day without lenses, and is increasingly used to help slow myopia progression in children. Regular contact lenses are worn during waking hours and correct vision only while in place.
