Q: Why Did My Farsightedness Suddenly Increase?

Increased hyperopia?

Hello, doctor: A year ago, I had an eye exam and was diagnosed with +2.50 diopters of hyperopia, for which I received a pair of glasses.
However, I hardly used them.
Recently, I noticed that my vision at both near and far distances has become somewhat blurry.
After another eye exam, my hyperopia has increased to +1.00 diopters, and I received new glasses with this prescription, which help me see more clearly.
Could you please explain why my hyperopia has suddenly increased? (When looking at things up close, I don’t experience any blurriness without my glasses.) Thank you for your response!

Hello: You may have had a hyperopia of 100 degrees, but during previous eye examinations, your ciliary muscles might have been exerted, resulting in a lighter measurement.
Now, since you are unable to exert that effort for accommodation, your vision may appear blurry.
This is likely a normal physiological phenomenon and should not be a cause for concern.

More Info

The sudden increase in your farsightedness (hyperopia) from +2.50 diopters to +1.00 diopters is indeed concerning and can be attributed to several factors. Farsightedness occurs when the eye is shorter than normal or the cornea has too little curvature, causing light rays to focus behind the retina. This condition can fluctuate due to various reasons, including changes in the eye's structure, the health of the eye, and even lifestyle factors.

1. Age-Related Changes: As we age, the lens of the eye becomes less flexible, which can lead to changes in vision. Although you may be relatively young, it’s still possible that natural changes in your eye's anatomy could be contributing to this increase in hyperopia.

2. Eye Health Conditions: Certain eye conditions can lead to changes in refractive error. For instance, cataracts, which cloud the lens of the eye, can cause changes in vision, including increased hyperopia. Other conditions, such as keratoconus or changes in the retina, could also be factors.

3. Inadequate Use of Corrective Lenses: Since you mentioned that you rarely wear your glasses, your eyes may not be accustomed to the correction they provide. This can lead to strain and discomfort, potentially exacerbating any underlying issues. Over time, not using corrective lenses can lead to a deterioration in visual acuity.

4. Environmental and Lifestyle Factors: Prolonged near work, such as reading or using screens, can lead to eye strain and may affect your vision. While you mentioned that your near vision is not affected, the overall strain on your visual system could still contribute to changes in your refractive error.

5. Genetic Factors: Family history can play a role in the development and progression of refractive errors. If there is a history of vision problems in your family, this could be a contributing factor.

6. Systemic Health Issues: Certain systemic health conditions, such as diabetes, can affect vision and lead to changes in refractive error. If you have any underlying health issues, it would be wise to discuss these with your healthcare provider.

Given these possibilities, it is crucial to follow up with an eye care professional. They can perform a comprehensive eye examination to assess the health of your eyes and determine the underlying cause of the sudden increase in your hyperopia. This may include checking for cataracts, assessing the health of the retina, and evaluating the overall structure of your eyes.

In the meantime, wearing your prescribed glasses consistently can help reduce eye strain and improve your visual comfort. Additionally, practicing good eye hygiene, such as taking regular breaks during prolonged near work and ensuring proper lighting, can help maintain your eye health.

If you experience any other symptoms, such as headaches, eye pain, or significant changes in vision, it is essential to seek medical attention promptly. Early intervention can help manage any potential issues and preserve your vision.
