Blurred or Distorted Near Vision

Presbyopia

Presbyopia, often referred to as "old eyes," is a condition where the eye loses its ability to focus on near objects, leading to blurry or distorted near vision. It typically begins to affect people between the ages of 40 and 45.

  • Cause of Presbyopia: The condition is caused by the loss of elasticity in the crystalline lens, the eye's natural lens located between the cornea and retina. Over time, the lens becomes less flexible, making it difficult to focus on close objects, much like how a camera's zoom function loses clarity over time.
  • Symptoms: People with presbyopia often experience difficulty reading small text or seeing close-up objects clearly. The sensation of text "dancing" or becoming blurry when reading is common.

How to Act?

  • Regular Eye Exams: After the age of 40, it is recommended to have a full ophthalmic check-up every 1-2 years.
  • Correction: Presbyopia can be corrected with:
    • Reading glasses or bifocals.
    • Refractive surgery may be an option in cases where presbyopia is combined with other refractive errors or cataracts.

Hyperopia

Hyperopia, or farsightedness, is another refractive error where images are focused behind the retina, resulting in blurred vision, particularly for close-up objects.

  • Symptoms: Blurred near vision, difficulty focusing on text or objects at a close distance.

How to Act?

  • Correction of Hyperopia:
    • Glasses or contact lenses with converging lenses can easily correct hyperopia.
    • Refractive surgery: Some corneal refractive surgery techniques are available for people with low degrees of hyperopia.
    • Phakic lenses (implanted between the cornea and crystalline lens) can be used for individuals with higher degrees of hyperopia.
    • Pseudophakic lenses (replacing the crystalline lens) are an option for those over 40-45 years.

Conclusion

Both presbyopia and hyperopia can be managed effectively with the right corrective measures. Regular eye exams are essential, especially as we age, to address near-vision difficulties and ensure optimal visual health.
