Light-coloured eyes and light sensitivity

Iris pigment helps absorb some incoming light. People with blue, green, or grey eyes may therefore find glare, sunlight, or harsh indoor lighting uncomfortable, particularly after moving from darkness into brightness. Sensitivity can also occur with dry eyes, an irritated surface, conjunctivitis, migraine, contact-lens problems, or inflammation inside the eye. Eye colour does not explain every episode, and it does not by itself diagnose a condition. Note whether the problem affects one eye or both and whether it is new.

Use sunglasses with appropriate ultraviolet protection outdoors, seek shade, and reduce glare from screens without sitting in complete darkness. Take contact lenses out if they feel uncomfortable and avoid rubbing the eyes. Lubricating drops may help some people, but choose them with pharmacist or clinician guidance if symptoms persist. Arrange an eye assessment when sensitivity is recurrent, worsening, or interfering with reading, driving, or ordinary indoor light.

Get urgent medical help for severe eye pain, sudden vision loss or marked blur, a very red eye, injury, unequal pupils, or light sensitivity with a severe headache, stiff neck, fever, confusion, or rash. These combinations can signal problems requiring rapid treatment, including meningitis or a serious eye disorder.

Ask whether the sensitivity is coming from the eye surface, a migraine pattern, medication, or another cause. Mention contact-lens use, recent injury or infection, headaches, discharge, and any change in vision.
