Increased sensitivity to bright light can have various causes, ranging in severity from 'minor' to 'very serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • understand what's happening to your body
  • see your health summarized and in detail
  • have a doctor review your case (optional)

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose increased sensitivity to bright light, 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 "increased sensitivity to bright light" as a symptom.  Here are eight of many possibilities (more below):
  • Macular Degeneration
  • Iritis
  • Vitamin B6 Need
  • Adrenal Fatigue
  • Dry Eye
  • Fluorosis
  • Pyroluria
  • Lupus (SLE)

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:
itchy eyes
unexplained fevers that hit hard
specific muscle weakness
hypothyroidism
microcytic red cells
hyperactivity
mild menopausal arthritis
meal-related bloating
irritated eyes
having a learning disability
chest pain when breathing
refined white flour consumption
... and more than 110 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of increased sensitivity to bright light:
Cause Probability Status
Adrenal Fatigue 92% Confirm
Pyroluria 17% Unlikely
Lupus (SLE) 13% Unlikely
Vitamin B6 Need 4% Ruled out
Fluorosis 0% Ruled out
Dry Eye 0% Ruled out
Macular Degeneration 0% Ruled out
Iritis 0% Ruled out
* This is a simple example to illustrate the process
