Refractive Errors

The Most Common Cause of Blurry Vision

Do you struggle to see distant objects clearly? Or perhaps you find reading small print is becoming difficult? These are signs of refractive errors—the most common vision problem affecting people of all ages. Refractive errors occur when the shape of your eye prevents light from focusing directly on the retina, leading to blurred or distorted vision.

The good news? Refractive errors are easily diagnosed and treatable with a variety of modern solutions ranging from spectacles, contact lenses, advanced optical therapies, and surgical procedures.

Types of Refractive Errors
Myopia (Nearsightedness)
  • What is it? You can see nearby objects clearly, but distant objects appear blurred.
  • Why does it happen? The eyeball is too long, or the cornea is too curved, causing light to focus in front of the retina.
  • On the rise: Myopia is becoming a global epidemic, especially among children due to increased screen time and reduced outdoor activities.
Hypermetropia (Farsightedness)
  • What is it? Distant objects are clearer, but near tasks like reading become difficult.
  • Why does it happen? The eyeball is too short, or the cornea has too little curvature, causing light to focus behind the retina.
  • Can cause eye strain, headaches, and fatigue, especially in children and young adults.
Astigmatism
  • What is it? Both near and distant vision appear blurred or distorted.
  • Why does it happen? An irregularly shaped cornea or lens prevents light from focusing evenly on the retina.
  • Often occurs in combination with myopia or hypermetropia.
Presbyopia (Age-related Farsightedness)
  • What is it? Difficulty in seeing near objects, such as reading or mobile screens, usually after age 40.
  • Why does it happen? The natural lens loses flexibility, reducing the eye’s ability to focus on close objects.
  • A universal condition that affects everyone with age.
Symptoms of Refractive Errors
  • Blurred vision.
  • Eye strain or discomfort.
  • Headaches, especially after reading or computer work.
  • Difficulty seeing at night.
  • Squinting to see clearly.
  • In children: Poor school performance, sitting too close to the TV, frequent rubbing of eyes.
Treatment Options for Refractive Errors
Spectacles (Eyeglasses)
  • Most common, safest, and easiest correction for refractive errors.
  • Wide range of lenses now available:
  • Anti-reflective and Blue-light filtering lenses to reduce screen fatigue.
  • Progressive lenses: Seamless transition from distance to near vision for presbyopia.
  • Hoya MiyoSmart Lenses: Specially designed for myopia control in children, slowing down the progression of myopia.
  • Photochromatic lenses: Change shade according to sunlight exposure.
  • High-index lenses: Thinner and lighter for high prescriptions.
  • Customized freeform lenses: Tailor-made for sharp vision with minimal aberrations.
Contact Lenses
  • Suitable for those seeking a glasses-free look or better peripheral vision.
  • Types of contact lenses:
  • Soft Lenses: For daily wear; comfortable for most users.
  • Toric Lenses: For correcting astigmatism.
  • Multifocal Lenses: For presbyopia correction.
  • Rigid Gas Permeable (RGP) Lenses: For precise correction in astigmatism and keratoconus.
  • Silicone Hydrogel Lenses: Allow more oxygen to reach the cornea, improving comfort.
  • Coloured Cosmetic Lenses: Correct vision and enhance eye color.
  • Specialty Scleral Lenses: For irregular corneas or severe dry eyes.
Orthokeratology (Ortho-K)
  • A non-surgical therapy involving custom-designed rigid contact lenses worn overnight to temporarily reshape the cornea.
  • Allows clear vision during the day without spectacles or contact lenses.
  • Effective in myopia control for children and for those unsuitable for LASIK.
  • Completely reversible and non-invasive.
Advanced Optical Therapies
  • Hoya MiyoSmart Lenses: Special spectacle lenses with DIMS (Defocus Incorporated Multiple Segments) technology to slow down myopia progression in children.
  • Stellest Lenses by Essilor: Another revolutionary lens technology for myopia control.
  • Contact Lens Myopia Control Solutions: Like MiSight® 1 day lenses designed for kids.
  • Atropine Eye Drops (Low-Dose): Emerging pharmacological treatment for myopia progression in children.

Latest Advancements in Presbyopia Treatment

Apart from progressive spectacles and multifocal contact lenses, recent pharmaceutical innovations are offering non-surgical solutions for presbyopia:

  • Presvu (Low-Dose Pilocarpine Eye Drops):
  • A novel FDA-approved eye drop therapy for presbyopia.
  • Works by temporarily improving near vision by reducing pupil size (pinhole effect), enhancing depth of focus.
  • Ideal for patients who want to reduce dependency on reading glasses for daily near tasks.
  • Effects last for several hours, offering flexibility for day-to-day activities.
  • Safe when prescribed after a detailed eye examination to rule out contraindications like retinal disorders or narrow angles.
Surgical Options
For those seeking permanent correction
  • Refractive Surgeries like LASIK, SMILE, Contoura Vision, Phakic IOLs (EVO ICL), and others.
  • Suitable for patients who desire to be spectacle/contact lens independent.
  • Requires eligibility assessment through detailed eye check-ups.
Importance of Regular Eye Check-Ups
  • Children should have annual eye exams, especially with increasing screen time and rising incidence of myopia.
  • Adults with refractive errors should check for progression and eye health.
  • Presbyopic individuals need regular evaluations for optimal near vision correction.
  • Early detection of other coexisting conditions like cataract, glaucoma, or retinal issues can be life-changing.

Frequently Asked Questions (FAQs)

  • Can refractive errors go away on their own?

    No. Refractive errors do not correct themselves naturally. Proper prescription glasses, contact lenses, or surgical options are needed for clear vision.

  • My child’s myopia is increasing every year. Can it be controlled?

    Yes. Modern options like Hoya MiyoSmart lenses, Ortho-K therapy, and low-dose atropine eye drops are effective in slowing down myopia progression in children.

  • Are contact lenses safe for daily use?

    Yes, when used responsibly with proper hygiene and following your eye doctor’s instructions. Regular check-ups are important for safe usage.

  • What are progressive lenses?

    Progressive lenses provide a smooth, gradual change in power from distance to near, eliminating the need for separate reading glasses.

  • Is Ortho-K a permanent correction?

    No. Ortho-K reshapes the cornea temporarily. Regular night-time wear of lenses is needed to maintain clear daytime vision.

  • When should I consider refractive surgery?

    Refractive surgery can be considered if you are above 18 years, have stable glasses power for at least a year, and have healthy eyes. A comprehensive eligibility test is necessary before surgery.

  • Can astigmatism be corrected with spectacles and contact lenses?

    Yes. Both toric spectacle lenses and toric contact lenses are designed to correct astigmatism effectively.

  • Can presbyopia be corrected without glasses?

    Presbyopia can be corrected with multifocal contact lenses, progressive spectacle lenses, or surgical options like multifocal IOLs after cataract surgery.
