Sensitivity to Temperature

Sensitivity to temperature is similar to light sensitivity, photophobia. It occurs  when there are abnormalities in the tear film and ocular surface.

The tear film may be insufficient and its ability to protect nerve endings may be compromised. Normally tear film protects the nerve endings as it spreads over a smooth eye surface. If the surface of the eye isn’t smooth (as with conjunctivochalasis) the  tear film may be unstable or inadequate, exposing the eye’s sensitive nerves to changes in temperature. The sensation can be extreme even with minor temperature changes.

When temperature sensitivity is constant, this is usually an indicator of a problem, including Dry Eye, for which medical attention should be sought.
