Eye Conditions

Most eye conditions are treatable — when caught early.

Common Eye Conditions That Affect Your Vision

Good vision is at the center of nearly everything we do — reading, driving, and recognizing the faces of the people we love. Yet many of the most common eye conditions develop quietly, often without obvious warning signs, until meaningful vision loss has already occurred.

Understanding what to watch for, and why routine care matters, can make an enormous difference in protecting your eyesight long-term. At Heffington’s, our experienced optometrists screen for these conditions as part of every comprehensive eye exam.

Eye Conditions We Screen For

Glaucoma

Glaucoma develops when the optic nerve is damaged. Several risk factors contribute, the most significant being elevated intraocular pressure (eye pressure). As the nerve deteriorates, peripheral vision narrows first, and without treatment, central vision can also be lost. What makes glaucoma particularly dangerous is that most forms produce no noticeable symptoms in the early stages. By the time you notice changes in your sight, irreversible damage may have already occurred. Because glaucoma can only be detected through a thorough eye pressure evaluation and optic nerve exam, your annual eye exam is your most effective line of defense.

Cataracts

A cataract forms when the eye’s natural lens — which normally focuses light onto the retina — becomes clouded, causing vision to appear blurry, hazy, or dimmed. Cataracts most often develop gradually with age and typically become bothersome after age 55. However, they can also be present at birth (congenital cataracts) or result from an eye injury (traumatic cataracts). Certain health conditions, including diabetes, and long-term use of medications such as corticosteroids can also accelerate their development.

Age-Related Macular Degeneration (AMD)

Macular degeneration affects the macula — the most sensitive area of the retina — which is responsible for the sharp central vision we rely on for reading, driving, and recognizing faces. As the macula deteriorates, central vision becomes increasingly compromised, though peripheral vision generally remains intact. Most people experience a slow, painless progression, with early signs that may include shadowy areas or distorted, fuzzy patches in their central field of view. In rare cases, AMD can advance more suddenly. Early detection through a dilated eye exam gives your optometrist the best opportunity to monitor and manage its progression.

A Promising New Treatment: Photobiomodulation

Previous management of dry AMD included vitamins, minerals, supplements, and diet changes to improve vascular health. But in late 2024, the FDA authorized photobiomodulation — a form of low-level light therapy — as the first non-invasive treatment cleared for dry AMD. This therapy uses specific wavelengths of red and near-infrared light to stimulate retinal cells at the mitochondrial level.

The retina depends heavily on cellular energy to function, and mitochondrial dysfunction is increasingly recognized as a key driver of AMD progression. By targeting cytochrome oxidase — a critical enzyme in the mitochondrial energy chain — photobiomodulation aims to support retinal cell health and slow the advance of the disease.

Clinical evidence indicates that patients who received the treatment showed modest improvements in visual acuity and were less likely to progress to geographic atrophy — a severe, sight-stealing stage of dry AMD — compared to a control group. If you or a loved one has been diagnosed with dry AMD, ask the Heffington’s team whether photobiomodulation may be an appropriate option.

Diabetic Eye Disease

Prolonged elevated blood sugar levels can damage the small blood vessels throughout the body — including those in the retina — leading to a condition called diabetic retinopathy. As those vessels break down, they may leak or grow abnormally, placing vision at serious risk. The risk of diabetic retinopathy increases the longer someone lives with diabetes, according to the American Academy of Ophthalmology. This is why an annual comprehensive eye exam is considered essential care for anyone managing diabetes, not just an optional step.

Why Routine Eye Exams Are Essential

Most serious eye conditions share a common trait: they cause their greatest damage before they cause obvious symptoms. A routine comprehensive eye exam gives your optometrist the opportunity to check eye pressure, evaluate the optic nerve, examine the retina, and identify early warning signs — often years before they would affect your day-to-day vision. We also assess and manage a broader range of vision disorders, and our team is available for emergency eye care when an urgent situation arises.

Don’t wait for symptoms to appear. The earlier a condition is detected, the more options are available to protect your vision.

Frequently Asked Questions

How often should I have an eye exam if I have diabetes?

If you have diabetes, you should schedule a comprehensive dilated eye exam at least once a year. Diabetic retinopathy can develop without any noticeable symptoms, which makes regular monitoring a critical part of overall diabetes management. Your optometrist may recommend more frequent visits depending on your eye health.

Can conditions like glaucoma or macular degeneration be prevented?

While most age-related eye conditions cannot be fully prevented, catching them early dramatically improves outcomes. Keeping conditions like diabetes and high blood pressure well-managed, protecting your eyes from UV exposure, and maintaining annual eye exams all support better long-term eye health.

When should I start getting screened for age-related eye conditions?

Adults should have a comprehensive eye exam every one to two years, and annually once they reach their 40s. Conditions like cataracts, glaucoma, and age-related macular degeneration become more prevalent with age, and earlier detection always means more treatment options.

Is photobiomodulation therapy covered by insurance for AMD?

Because the FDA has authorized photobiomodulation for dry AMD — rather than fully approving it — some insurers may categorize it as investigational and decline coverage. We recommend contacting your insurance provider directly. Learn more about insurance we accept.

What is the difference between an optometrist and an ophthalmologist when it comes to managing eye disease?

Optometrists are trained to diagnose and co-manage many common eye conditions, and they frequently coordinate with ophthalmologists — eye surgeons — when advanced treatment is needed.
