Vision Disturbances

What Causes Vision Disturbances?

Vision disturbances can have various causes, ranging in severity from 'troubling' to 'generally fatal'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • check your overall health status
  • have a doctor review your case (optional)
  • identify any nutritional deficiencies

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose vision disturbances, 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 "vision disturbances" as a symptom.  Here are eight of many possibilities (more below):
  • Chronic Fatigue-Fibromyalgia
  • Iritis
  • Metal Toxicity
  • Brain Tumor
  • Overtraining
  • Aspartame/Neotame Side-Effects
  • Multiple Sclerosis
  • Adrenal Fatigue

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:
history of brain cancer
red palms/fingertips
peripheral vision loss
adrenal insufficiency
seizures
low diastolic blood pressure
darker/redder skin color
very watery eyes
severe fatigue after slight exertion
history of bulimia
weak appetite
hand tremors
... and more than 150 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of vision disturbances:
Cause Probability Status
Overtraining 95% Confirm
Iritis 20% Unlikely
Aspartame/Neotame Side-Effects 15% Unlikely
Metal Toxicity 2% Ruled out
Adrenal Fatigue 0% Ruled out
Brain Tumor 0% Ruled out
Chronic Fatigue-Fibromyalgia 0% Ruled out
Multiple Sclerosis 0% Ruled out
* 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.

If you indicate eye problems, The Analyst™ will ask further questions including this one:
Vision disturbances. Aside from any long/short-sightedness, does your vision sometimes become blurry or otherwise distorted, for example double vision?
Possible responses:
→ No / don't know
→ Occasionally / moderately
→ Often / severely
Based on your response to this question, which may indicate either vision disturbances or severe vision disturbances, The Analyst™ will consider possibilities such as:
Brain Tumor

Double vision, especially if it is associated with headache, is a significant symptom of a brain tumor.

Dehydration

Vision disturbances can occur due to eye strain resulting from reduced lubrication (tear production).  The body responds to dehydration by trying to conserve as much fluid as possible, including fluid in the eyes.

Diabetes Type II

High blood sugar can cause two problems which affect vision, namely blurred vision and retinopathy – a disease of the back of the eye.  Blurred vision is one of the first signs of elevated blood sugar.  The shape and size of the lens in your eye changes when your blood sugar fluctuates.  This swelling of the lens can cause blurred vision.

If you notice blurred vision, you should have your blood sugar checked.  The acceptable range for fasting glucose is 80-110mg.  If your blood sugar is substantially higher or lower than the acceptable range, contact your doctor.  When your blood sugar is controlled, your vision will return to its previous state.

Hypoglycemia

Blurred vision and diplopia (double-vision) are possible symptoms.

Macular Degeneration

In the early stages, central vision may be blurred or distorted, with things looking an unusual size or shape.  This may happen quickly or develop over several months.

Mercury Toxicity (Amalgam Illness)

Intermittent blurred distance vision is a sign of mercury toxicity.
