Why does it still hurt when I blink when nothing gets in my eye?

Often, the cause of this condition is only temporary. For example, staring at a computer screen for many hours at a time can cause eye pain when blinking. This condition is called computer vision syndrome, according to the health website Healthline (USA).

Because when using a computer, users will constantly look at the screen and tend to blink less than usual. As a result, the cornea is not properly moisturized, leading to dry eyes, pain, and irritation when blinking.

Avoiding prolonged exposure to computer screens and taking frequent breaks can help reduce discomfort. However, for some people, these problems recur due to chronic dry eyes. Dry eyes are often caused by aging, exposure to ultraviolet light, or certain health problems. Severe dry eyes require medical treatment.

Dry eyes are not the only cause of stinging when blinking. Allergic conjunctivitis can cause similar symptoms if the sufferer is exposed to allergens such as pollen or mold. These substances irritate and inflame the mucous membrane that covers the surface of the eyeball, leading to stinging when blinking.

This feeling is also a typical symptom of conjunctivitis, also known as pink eye. The causative agent is usually bacteria or viruses. The risk of transmission from one person to another is also very high.

If your eyes are sore and not due to allergies, infection, or dry eyes, you may have an injury. If you have sore eyes and can’t find a foreign object in your eye, you may have a scratch on your cornea. These scratches can cause a sharp, burning sensation when you blink.

Depending on the cause of your sore eyes, there are many ways to treat them at home. However, the general rule is that if after 2 days the condition does not improve or even gets worse, you should go to the hospital immediately, according to Healthline .
