Refractive Errors

Refractive errors occur when the shape of the eye prevents light from focusing properly on the retina. This causes blurry vision at near, distance, or both. Common types include myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related difficulty focusing up close).

At The Medical Group of New Jersey, our ophthalmology team provides complete evaluation, personalized treatment, and guidance on glasses, contact lenses, and surgical options to help you see clearly and comfortably in daily life.

Symptom Onset & Initial Evaluation

Refractive errors often develop gradually, though some people notice changes more quickly. Common symptoms include:

• Blurry distance or near vision
• Squinting to see clearly
• Eye strain or headaches
• Difficulty reading or driving at night
• Trouble focusing when shifting between near and far tasks

During your evaluation at The Medical Group of New Jersey, your ophthalmologist will:

• Review vision changes, daily visual needs, and any history of eye strain
• Perform a comprehensive eye exam, including visual acuity
• Conduct a refraction test to determine your exact prescription
• Evaluate eye health to rule out other causes of vision changes
• Discuss lifestyle factors, such as screen time or night driving challenges

If you wear glasses or contacts, we will also review your current prescription and comfort level.

Diagnosis & Risk Assessment

Diagnosis is based on determining how light focuses inside the eye and identifying the specific refractive error.

Types of Refractive Errors

• Myopia (Nearsightedness): Clear near vision; blurry distance vision. Often develops during childhood or adolescence.
• Hyperopia (Farsightedness): Clear distance vision; difficulty up close. May cause eye strain or headaches.
• Astigmatism: Irregular corneal shape causes distorted or “shadowed” vision at all distances.
• Presbyopia: Age-related loss of near focus, typically beginning in the 40s. Difficulty reading small print or needing to hold items farther away.

Diagnostic Tools

• Refraction testing (lens adjustments to identify the best correction)
• Keratometry or topography (measures corneal curvature, especially in astigmatism)
• Retinal exam to rule out coexisting eye disease
• Visual acuity chart testing at various distances

Your ophthalmologist will also assess how your visual needs, such as computer work, driving, sports, or reading, should guide your treatment plan.

Treatment & Management

Treatment focuses on achieving clear, comfortable vision based on your lifestyle and visual goals.

Corrective Lenses

• Glasses are the most common and simplest treatment
• Contact lenses (soft, rigid gas-permeable, or toric for astigmatism)
• Multifocal lenses for presbyopia
• Progressive lenses for seamless distance-to-near focus

Your ophthalmologist will help you choose the best option based on comfort, eye health, and daily habits.

Refractive Surgery Options

For appropriate candidates, surgical correction may be recommended:

• LASIK: Reshapes the cornea for myopia, hyperopia, or astigmatism
• PRK: Alternative to LASIK for certain corneal shapes or dry eye
• Refractive lens exchange (RLE): May be used for severe refractive errors or presbyopia

We provide a full evaluation to assess candidacy for surgery and discuss expected results, risks, and recovery.

Lifestyle & Visual Comfort Strategies

• Using appropriate lighting when reading
• Taking regular screen breaks (20-20-20 rule)
• Managing dry eye symptoms that may worsen visual clarity
• Wearing sunglasses for UV protection

Monitoring & Follow-Up

Routine follow-up helps ensure your prescription remains accurate and your eyes stay healthy. Your ophthalmologist at The Medical Group of New Jersey will:

• Update your glasses or contact prescription as needed
• Recheck refraction when you notice blurriness or eye strain
• Monitor for age-related changes such as cataracts or presbyopia
• Evaluate contact lens fit and eye surface health if you wear lenses

Most patients benefit from a comprehensive eye exam every 1–2 years, or more often if symptoms change or underlying conditions (such as diabetes) are present.

Clear vision often improves immediately with proper treatment, and refractive errors can be effectively managed throughout life with regular care.
