So we can say that if you have eye allergies, it will increase the risk to be sensitive to light. For the reason, you should know that certain pollens or irritants (such as dust or pollution) are perceived by the body's immune system as an invader, causing a range of symptoms such as runny or watery eyes, itching, a burning sensation, dryness and sensitivity to light. If you are experiencing any symptoms of sensitive eyes, you'd better seek help from a medical professional as soon as possible.
