Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose nearsightedness or farsightedness, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Eyes/Ocular Symptoms section of the questionnaire, The Analyst™ will ask the following question about nearsightedness, farsightedness, or astigmatism:
Are you nearsighted (far away objects are blurry), farsighted (close objects are blurry), or astigmatic (everything appears blurry/distorted) in one or both eyes? In other words, do you need corrective lenses (eyeglasses or contact lenses) to see clearly?
Possible responses:
→ No, my vision is fine / I am blind / don't know
→ I have had corrective eye surgery (LASIK, etc.)
→ Astigmatism ONLY (everything appears blurry)
→ Astigmatism AND nearsighted/farsighted combined
→ I am nearsighted or farsighted in one or both eyes
Based on your response to this question, which may indicate having normal uncorrected vision, having had corrective eye surgery, having astigmatism, being astigmatic and near/farsighted or being nearsighted or farsighted, The Analyst™ will ask further questions about:
