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.
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:
|Aspartame/Neotame Side-Effects||3%||Ruled out|
|Chronic Fatigue-Fibromyalgia||3%||Ruled out|
|Multiple Sclerosis||0%||Ruled out|
|Brain Tumor||0%||Ruled out|
|Adrenal Fatigue||0%||Ruled out|
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

Double vision, especially if it is associated with headache, is a significant symptom of a brain tumor.
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.
Blurred vision and diplopia (double-vision) are possible symptoms.
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.
Intermittent blurred distance vision is a sign of mercury toxicity.
