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):

Lupus (SLE)
Vitamin B6 Need
Pyroluria
Dry Eye
Macular Degeneration
Fluorosis
Adrenal Fatigue
Infectious Mononucleosis

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:

Heberden's nodes

tender muscles

poor tolerance of heat

difficulty swallowing

high refined white flour consumption

having a high fever

lighter/paler skin color

shingles

history of B6 deficiency

frequent aspirin use

history of cysts in breasts

current atypical headaches

... and more than 130 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
Dry Eye	93%	Confirm
Infectious Mononucleosis	29%	Unlikely
Adrenal Fatigue	21%	Unlikely
Lupus (SLE)	5%	Ruled out
Macular Degeneration	0%	Ruled out
Vitamin B6 Need	0%	Ruled out
Pyroluria	0%	Ruled out
Fluorosis	0%	Ruled out

* This is a simple example to illustrate the process
