LEARN: REFRACTIVE/VISION CONDITIONS

Why Is My Vision Blurry? Exploring Vision Problems

OVERVIEW

Blurry vision, trouble reading up close, or difficulty seeing far away? These could be signs of refractive errors—common vision problems that affect how your eyes focus light. This page explains conditions like nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia in a way that’s easy to understand. Learn what causes these issues, how they impact your daily life, and the simple solutions (like glasses, contacts, or surgery) that can help you see clearly again.

  • Core Refractive Errors:

    • Myopia (Nearsightedness): Causes (elongated eyeball, genetics), symptoms, and correction options (glasses, contacts, surgery).

    • Hyperopia (Farsightedness): Causes (short eyeball, lens changes), symptoms, and correction options.

    • Astigmatism: Causes (irregular corneal shape), symptoms (distorted vision), and correction options.

    • Presbyopia: Causes (aging lens), symptoms (difficulty with near vision), and correction options (reading glasses, multifocals).

  • Advanced Refractive Concepts:

    • Anisometropia: Unequal refractive errors between eyes, impact on vision, and management.

    • High Myopia: Risks (retinal detachment, myopic maculopathy) and monitoring.

    • Secondary Refractive Errors: Post-cataract surgery, post-LASIK changes.

  • Pediatric and Developmental Considerations:

    • Refractive Errors in Children: Myopia progression, hyperopia in infancy, and amblyopia risk.

    • Myopia Control: Strategies (atropine drops, ortho-k lenses, multifocal contacts).

  • Surgical and Non-Surgical Corrections:

    • Refractive Surgery: LASIK, PRK, SMILE, and patient suitability.

    • Phakic IOLs and Refractive Lens Exchange: Options for high refractive errors.
