What Could be Causing Poor Eye Focus?

What Causes Poor Eye Focus?

Poor eye focus can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

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

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

The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "poor eye focus" as a symptom. Here are two possibilities:

Presbyopia
Premature Aging

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:

poor balance

some muscle wasting

often waking up with dry eyes

reduced sense of smell

reduced skin elasticity

specific muscle weakness

slow reaction time

increased skin wrinkling

some loss of muscle tone

loss of interest in activities

rapidly declining health

major joint pain/swelling/stiffness

... and so on

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of poor eye focus:

Cause	Probability	Status
Presbyopia	97%	Confirm
Premature Aging	57%	Possible

* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

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 eye focusing ability:

How well can your eyes focus on close objects? Slowly bring a newspaper or book closer to your eyes. Without wearing glasses or contact lenses, approximately how far from your eyes is the page when the regular-size letters start to blur?

Possible responses:

→ I can't do this test / don't know
→ Less than 4 inches (10cm)
→ 4-11 inches (10-28cm)
→ 12-36 inches (30-90cm or 1-3 feet)
→ Over 36 inches (90cm or 3 feet)

Based on your response to this question, which may indicate short focal length, average focal length, increased focal length or long focal length, The Analyst™ will consider possibilities such as:

Premature/Signs of Aging

Presbyopia

... and also rule out issues such as:

Presbyopia
