Common Eye Disorders and When to See an Eye Doctor

When to See the Eye Doctor

Eye disorders are incredibly common, affecting millions of people in the U.S. alone. While occasional irritation or puffiness doesn’t always require medical attention, it’s important to know when a symptom is more than just an inconvenience.

If you’re experiencing persistent blurred vision, sudden vision loss, eye pain, or symptoms that seem to be getting worse over time, it’s a good idea to schedule an appointment with an optometrist or ophthalmologist. Early detection is key when it comes to protecting your long-term eye health. Below, learn about a variety of eye conditions, their symptoms, and treatments.

Astigmatism and Blurred Vision

Astigmatism causes blurred or distorted vision due to an irregularly shaped cornea. A normal cornea is round and focuses light properly; an astigmatic cornea bends light unevenly.

This condition is typically treated with corrective contact lenses. Some popular brands designed to correct astigmatism include:

Refractive surgeries such as LASIK may also be considered in some cases.

Understanding Glaucoma Symptoms

Glaucoma refers to a group of eye diseases that can damage the optic nerve, often due to increased pressure inside the eye. It can lead to permanent vision loss if untreated.

Symptoms include peripheral vision loss, halos around lights, nausea, and eye pressure. If you notice any of these signs, it’s crucial to visit your eye doctor immediately.

Though there is no cure, glaucoma can be managed with medications, eye drops, or surgery.

Macular Degeneration: A Silent Threat

Macular degeneration is the leading cause of vision loss among older adults. It occurs when the macula—the part of the retina responsible for sharp central vision—deteriorates or when abnormal blood vessels grow beneath it.

Symptoms can include gradual vision loss or blank spots in your central field of vision. However, because the brain often fills in missing visual information, it can go unnoticed.

If you experience any of these symptoms or are over 50 and have never been screened, see an eye doctor. While contact lenses won’t treat macular degeneration, brands with high oxygen delivery and UV protection like Biofinity or Acuvue Vita may be recommended for overall eye health.

Pink Eye (Conjunctivitis) and Eye Infections

Conjunctivitis, commonly known as pink eye, is an infection or inflammation of the conjunctiva—the thin membrane that lines the eyelid and covers the white of the eye.

The pink appearance is due to inflammation of blood vessels. It can be caused by bacteria, viruses, or allergies. While mild cases may resolve with good hygiene and warm compresses, severe or prolonged cases should be evaluated by a doctor.

Contact lens users should discontinue lens wear during infection. For those prone to irritation, daily disposables like 1-Day Acuvue Moist or Clariti 1 Day can reduce future risk.

Eye Allergies and Redness

Eye allergies are caused by environmental triggers like pollen, dust mites, or pet dander. They lead to redness, itching, and watery eyes. While many cases are seasonal, some people experience symptoms year-round.

Mild allergies can be managed with lubricating drops and antihistamines. However, if symptoms persist or worsen, it’s wise to consult an eye care provider.

Those with allergies may benefit from daily disposable lenses to reduce exposure to allergens. Consider options like Dailies AquaComfort Plus or MyDay Daily Disposable.

What Do Doctors See When They Look in Your Eye?

During an eye exam, your doctor can assess much more than just your vision. By examining the back of your eye (the retina), they can detect signs of systemic conditions like diabetes, high blood pressure, or even neurological disorders.

Using instruments like a slit lamp, ophthalmoscope, and tonometer, your eye doctor evaluates the retina, optic nerve, macula, and intraocular pressure to catch early signs of diseases you may not yet feel or notice.
