If you are experiencing chronic redness in your eyes, you are not alone. This condition is quite common and rarely serious, but it can be annoying or unsightly. There are many causes of red, bloodshot eyes, and maybe you can identify one of these as the culprit:
Allergies are not isolated to just spring and fall. Common allergens that cause red eyes include pollen, mold, ragweed, pet dander, and dust. Other symptoms of allergic conjunctivitis are itchy, watery eyes that may sting or feel inflamed.
Dry eye is a result of tear glands not producing enough tears to keep your eyes lubricated. Eyes may feel scratchy and irritated. This condition is especially problematic in arid, winter temperatures.
Pink eye, or conjunctivitis, is a highly contagious infection of the conjunctiva that makes the eyes red. Telltale signs of pink eye are watery eyes and a yellowish discharge.
Overuse of contact lenses
Contact lenses require daily maintenance and care. Over-wearing contact lenses or improperly caring for contact lenses allows for irritants to build up on the surface of the lens. Long-term exposure to irritants can lead to infections and vision problems.
Digital eye strain
Staring at a computer or tablet for too long can make eyes feel dry and burning, which may cause you to want to rub your eyes. This can cause eye redness as well.
Tobacco smoke contains hundreds of chemicals that irritate the eyes and cause them to be red or bloodshot.
Cold and flu
Sinus infection, cold virus or flu virus can make eyes puffy and red.
Treatments for red, bloodshot eyes
Treating red, bloodshot eyes will vary from patient to patient, depending on the cause of redness. Sometimes, red eyes will go away on their own, but it is best to make an appointment with your eye doctor to rule out any infection. If you cannot get in to see your eye doctor right away, you can place a cold compress on your eyes or apply over-the-counter eye drops. Do not delay in contacting your doctor. Delaying treatment could require more serious intervention such as antibiotics or even surgery (Source: All About Vision).
