why are my eyes stinging

The most common reasons why eyes might sting include dryness, irritation from foreign substances, allergies, infections like conjunctivitis (pink eye), or inflammation such as blepharitis. Environmental factors like smoke, dust, or exposure to chemicals can also cause stinging sensations. Contact lens use or improper care can lead to corneal infections or abrasions, causing pain and stinging. If the irritation persists or is severe, it is important to see an eye doctor for proper diagnosis and treatment as some causes may require medical attention.
