Common Eye Problems: Causes, Symptoms, and Treatments


The health of your eyes is vital to your quality of life. Good vision helps you take in the world and enjoy activities like reading, driving, and playing sports. However, many people experience common eye problems that can cause vision loss and other issues.

While some eye problems are minor and require no treatment, others can be more serious and require medical intervention. This article will examine some of the most common eye problems, their causes, symptoms, and treatment options.


Astigmatism is a prevalent eye condition that occurs when the front surface of the eye, the cornea, is curved more sharply in one direction than in the other. This curvature prevents light from focusing directly on the retina, the back surface of the eye, resulting in blurred vision. Astigmatism can occur in people of all ages, but it is most common in children. In most cases, astigmatism is mild and does not require treatment.

However, severe astigmatism can cause significant vision problems and may require glasses or contact lenses to correct. Astigmatism is usually diagnosed during a comprehensive eye exam. If you think you may have astigmatism, be sure to schedule an appointment with an eye care professional.

Fuchs dystrophy

Fuchs dystrophy is a common problem in the eye. It affects the cornea, which is the eye’s clear, curved front surface. The cornea contains tiny blood vessels that nourish it. These vessels grow into the cornea in Fuchs dystrophy, making it thick and cloudy. As the disease progresses, the cornea can swell and distort your vision. Symptoms of Fuchs dystrophy include blurred vision, glare, and halos around lights. The condition is progressive, so symptoms can get worse over time.

The keratoconus cross-linking surgery can help prevent the condition from getting worse. Like astigmatism, the disease is usually diagnosed during a comprehensive eye exam so go see your doctor if you think you may have it.


Conjunctivitis, also known as pink eye, is a common eye condition that occurs when the conjunctiva, the clear lining of the eye, becomes inflamed or irritated. Conjunctivitis can be caused by bacteria, viruses, allergies, or other irritants. Symptoms of conjunctivitis include redness, itching, tearing, and a discharge from the eye. The condition is usually mild and goes away on its own. However, severe cases may require treatment with antibiotics or other medications.

Age-Related Macular Degeneration

Age macular degeneration is an eye disease in which the macula, the main part of the retina concerned with clear, central vision, starts to deteriorate. Age-related macular degeneration (AMD) is the most prevalent form, affecting over 16 million people in the United States alone. AMD occurs when the cells in the macula break down and are no longer able to function. This leads to a loss of central vision and makes it difficult to see fine details. There are two types of AMD: dry AMD and wet AMD. What are these two? Dry AMD is the most common type and progresses slowly. Wet AMD is less common but more severe and can lead to rapid vision loss. There are no treatments for dry AMD, but treatments are available for wet AMD. Early diagnosis and treatment of wet AMD are essential for preventing vision loss.

A cataract is a clouding of the lens in the eye that causes vision to deteriorate. Cataracts often develop gradually and may at first appear harmless. A cataract might be a minor flaw in the lens that has no significant impact on vision. However, over time, the cataract can become larger and more opaque, causing more severe symptoms such as blurred or double vision, difficulty seeing at night, and light sensitivity. In some cases, cataracts can also cause complete blindness. In the United States, cataracts are the leading cause of blindness in adults over 40. Fortunately, cataracts can be treated with surgery. During the procedure, the cloudy lens is removed and replaced with an artificial lens. With treatment, most people with cataracts regain good vision.


Glaucoma is a severe eye condition that can lead to blindness. It occurs when the pressure inside your eye becomes too high, damaging the optic nerve. And while glaucoma can occur at any age, it is most common in older adults. Symptoms of glaucoma include blurred vision, severe headaches, and eye pain. If not treated promptly, glaucoma can cause irreparable damage to the optic nerve and lead to blindness. Early diagnosis and treatment are essential for preventing vision loss. There are several different types of glaucoma, and each type requires its unique treatment approach. If you are experiencing any symptoms of glaucoma, see an eye doctor as soon as possible. Early detection and treatment can help to preserve your vision.

The bottom line

Many common eye problems can occur. Going to the doctor for eye checkups is the best way to catch these conditions early and prevent or treat them accordingly. And, of course, always be sure to practice good eye health habits, such as wearing sunglasses and protecting your eyes from the sun.
