At Asheville Vision and Wellness, we believe that understanding what's happening with your eyes is the first step toward better eye health. This guide walks through the most prevalent eye conditions we see and manage, covering their symptoms, causes, and available treatments.
Quick Summary
- Common eye conditions include myopia, hyperopia, astigmatism, presbyopia, cataracts, glaucoma, AMD, dry eye syndrome, and diabetic retinopathy
- Many conditions share overlapping symptoms, such as blurred vision or eye strain, making professional diagnosis essential
- Most conditions are highly manageable when caught early through regular comprehensive eye exams
- Asheville Vision and Wellness offers medical testing and management for a wide range of eye diseases and vision conditions
Refractive Errors: The Most Common Vision Problems
Refractive errors are the most frequently diagnosed vision conditions in the world. They occur when the shape of the eye prevents light from focusing directly on the retina, resulting in blurred or distorted vision. Most refractive errors are easily corrected with prescription eyeglasses, contact lenses, or, in some cases, LASIK evaluation. The right solution depends on the type and degree of refractive error involved, which is why a thorough eye exam is always the essential starting point.
1. Myopia (Nearsightedness)
Myopia means you can see nearby objects clearly, but distant objects appear blurry. It develops when the eyeball is slightly too long or the cornea is too curved, causing light to focus in front of the retina rather than directly on it. Myopia often begins in childhood and may progress through the teenage years before stabilizing.
Common symptoms include:
- Squinting to see distant objects clearly
- Headaches after activities like driving or watching television
- Difficulty reading a whiteboard or street signs
Treatment options include prescription eyeglasses, contact lenses, and LASIK evaluation for eligible candidates. At Asheville Vision and Wellness, we offer LASIK consultations and refer surgical candidates to the Woolfson Eye Institute, whose team has performed more than 100,000 LASIK procedures.
2. Hyperopia (Farsightedness)
Hyperopia is essentially the opposite of myopia. People with this condition see distant objects more clearly than those up close. It occurs when the eyeball is shorter than typical or the cornea has too little curvature, causing light to focus behind the retina. Mild hyperopia is sometimes compensated naturally by the eye's own lens, but over time — particularly with age — that compensation becomes less effective. Prescription eyeglasses or contact lenses are the primary treatment.
3. Astigmatism
Astigmatism occurs when the cornea or lens has an irregular, football-like curvature rather than a smooth, spherical shape. This uneven surface causes light to refract at multiple angles, producing blurred or distorted vision at any distance. It frequently occurs alongside myopia or hyperopia.
People with astigmatism may notice:
- Blurred or wavy lines when reading
- Difficulty seeing clearly in low light
- Eye strain and general visual fatigue
Astigmatism is corrected with specially designed prescription lenses, including contact lenses made specifically for this condition. Read our blog post on what astigmatism is and what can be done about it for a deeper look at this condition.
4. Presbyopia
Presbyopia is a natural part of aging. Around the age of 40, the lens inside the eye gradually loses its flexibility, making it harder to focus on close objects. If you've found yourself holding your phone or a menu at arm's length to read it clearly, presbyopia is likely the reason. Unlike other refractive errors, it is not caused by the shape of the eye but by the gradual stiffening of the lens itself. Reading glasses, bifocals, progressives, and multifocal contact lenses are all effective solutions.
Cataracts
Cataracts are one of the leading causes of vision impairment worldwide. They develop when the clear lens inside the eye becomes cloudy, reducing the amount of light that reaches the retina. Most cataracts form slowly over many years as a natural result of aging, though other factors can accelerate their development.
Symptoms and Causes
The gradual nature of cataracts means symptoms often develop quietly. You might first notice that colors appear less vibrant, that you need brighter light for reading, or that glare from headlights at night has become more bothersome. As the condition progresses, vision becomes increasingly hazy or cloudy overall.
Risk factors include:
- Natural aging, which is the most common cause
- Diabetes (people with diabetes are 60% more likely to develop cataracts and may develop them at a younger age)
- Prolonged sun exposure without UV protection
- Certain medications, including long-term corticosteroid use
- Previous eye injury or surgery
Treatment
Cataracts cannot be reversed with medication or eyeglasses alone. When vision is significantly impacted, surgical removal is the standard treatment. Asheville Vision and Wellness offers evaluations for cataract surgery and manages post-operative care, coordinating with surgical specialists to ensure continuity of care throughout the process.
Glaucoma
Glaucoma is often called the "silent thief of sight" because it can cause significant, irreversible vision loss before noticeable symptoms appear. It refers to a group of conditions that damage the optic nerve, most commonly due to elevated pressure inside the eye. Because of its quiet progression, regular eye exams are the most reliable way to detect it early.
Who Is at Risk?
People with diabetes are 40% more likely to develop glaucoma. Additional risk factors include a family history of the disease, being over age 60, having naturally elevated eye pressure, and certain anatomical characteristics of the eye's drainage angle.
Common warning signs, when they do appear, include:
- Gradual loss of peripheral (side) vision
- Tunnel vision in more advanced stages
- Blurred vision or halos around lights
- Eye pain or redness, particularly with acute angle-closure glaucoma
How We Test and Monitor It
Glaucoma can be detected through several of the advanced diagnostic tests offered at Asheville Vision and Wellness. The Tonometry Test measures pressure inside the eye, and the Visual Fields Test checks for blind spots in peripheral vision. Optical Coherence Tomography (OCT) and Optomap Ultra-Widefield Retinal Imaging also help detect early optic nerve changes. The Rabin Cone Contrast Test (RCCT) is now part of our diagnostic toolkit for patients with glaucoma, detecting disease-related changes with exceptional sensitivity alongside these other tests. Treatment typically involves prescription eye drops to lower eye pressure, and regular monitoring is essential to prevent further damage.
Age-Related Macular Degeneration (AMD)
Age-related macular degeneration affects the macula, the central portion of the retina responsible for sharp, detailed vision. It is a leading cause of vision loss among people over 50 and often progresses slowly, which is precisely why early detection is so important. Many people dismiss the earliest signs as a normal part of getting older, and that delay can allow the disease to advance unnecessarily.
Symptoms of AMD can include:
- Trouble seeing clearly in dim or low light
- Blurred or distorted central vision
- Difficulty recognizing faces or reading fine print
- Gradual reduction in color brightness or clarity
Risk factors include being over age 50, having a family history of AMD, being Caucasian, smoking, and having low macular pigment density in the eye.
Asheville Vision and Wellness uses the AdaptDx Pro test, powered by artificial intelligence, to measure dark adaptation speed. This may indicate the presence of AMD up to three years earlier than many traditional tests. We also perform the Macular Pigment Density Test (MPOD), which checks the amount of protective pigment in the macula. If AMD is detected, proactive steps such as lifestyle changes, eye health supplements, and blue light protection can help delay further progression.
Dry Eye Syndrome
Dry eye is an extremely common condition, yet it is frequently underestimated. It occurs when the eyes either do not produce enough tears or produce tears that evaporate too quickly, leaving the eye surface inadequately lubricated. The burning, irritation, and fatigue associated with dry eye can significantly affect daily quality of life.
What Causes Dry Eye?
The causes of dry eye are varied and often interconnected:
- An imbalance in the tear-flow system
- Extended screen time, which reduces the natural blink rate
- Air conditioning, heating systems, or dry environmental conditions
- Natural aging and hormonal changes, including menopause
- Certain medications, including antihistamines
- Underlying conditions such as rheumatoid arthritis or certain vascular diseases
Treatment Options
Asheville Vision and Wellness offers a range of dry eye treatments tailored to the underlying cause. At-home options like preservative-free artificial tear drops, warm compresses, and blinking exercises can provide relief for mild cases. For more persistent or severe dry eye, especially when Meibomian Gland Dysfunction (MGD) is involved, we offer LipiFlow, a specialized treatment that applies gentle heat and massage to clear blocked oil glands and restore the natural tear film. Punctal plugs and prescription eye drops are also among the options our doctors may recommend depending on your individual needs.
Diabetic Retinopathy
Diabetes is the leading cause of blindness among adults in the United States. Diabetic retinopathy develops when elevated blood sugar levels damage the blood vessels that supply the retina. These vessels may swell, leak, or grow abnormally, all of which can threaten vision. Retinopathy caused by diabetes accounts for 12% of new cases of blindness in the U.S., making regular diabetic eye exams a critical part of managing this disease.
Symptoms can include:
- Blurry or cloudy vision
- Floating spots or dark strings in the visual field
- Seeing flashing lights
- Blind or dark spots
- Double vision or sudden vision loss
Asheville Vision and Wellness offers medical testing and management specifically for patients living with diabetes and its impact on eye health. Early detection through comprehensive eye exams gives patients and their care teams the best opportunity to address changes before vision loss occurs.
Frequently Asked Questions
How do I know if I have an eye condition if I'm not having obvious symptoms?
Many serious eye conditions, including glaucoma and AMD, can progress without noticeable symptoms in the early stages. This is why annual comprehensive eye exams are so important. Our doctors use advanced imaging and diagnostic tools to detect signs of disease long before you might notice a change in your vision.
Can eye conditions like glaucoma or AMD be cured?
Most chronic eye diseases cannot be cured, but they can be effectively managed. With early detection and appropriate treatment, most people are able to preserve meaningful vision and slow or stop disease progression. The key is regular monitoring and prompt action when changes are identified.
How often should I have my eyes examined?
For most adults, a comprehensive eye exam once a year is recommended. People with diabetes, a family history of eye disease, or other risk factors may benefit from more frequent exams. Children should have their vision evaluated regularly as well, since vision problems can affect learning and development.
Are refractive errors like myopia permanent?
Myopia and other refractive errors do not go away on their own, but they can be corrected very effectively with eyeglasses, contact lenses, or LASIK. For adults whose prescription has been stable, LASIK may provide a long-term correction option. Asheville Vision and Wellness offers LASIK consultations to help you understand whether you may be a good candidate.
What should I do if I notice a sudden change in my vision?
Sudden changes in vision — including new floaters, flashing lights, or a shadow in your field of view — should be evaluated by an eye care professional as soon as possible. These symptoms can indicate serious conditions that require prompt attention.
