Hyperopia
Also known as Farsightedness, Hypermetropia, Long-Sightedness, Near Vision Blur, Plus Prescription
Bottom Line
Hyperopia means close work can look blurry or tiring because the eye focuses light too far back. Glasses, contacts, or surgery can move the focus back onto the retina.
Hyperopia is a refractive error. That means the eye has trouble focusing light clearly. In many people, the eye is a little too short from front to back. Light tries to focus behind the retina instead of on it 1.
Mild hyperopia can hide for years. The lens inside the eye can flex to make up for it. That extra focusing work can cause tired eyes, headaches, or blurry near vision 2.
In children, stronger hyperopia can raise the risk of crossed eyes and lazy eye. A pediatric eye exam can find this early and decide whether glasses are needed 1.
Symptoms
Hyperopia symptoms can be mild or easy to miss.
- Blurry near vision. Reading, phones, and crafts may be hard.
- Eye strain. The eyes work harder to focus.
- Headaches. These often happen after school, screens, or desk work.
- Squinting. Some people squint to sharpen vision.
- Eye crossing in children. Strong hyperopia can trigger an inward eye turn.
Studies in preschool children link moderate hyperopia with lower near vision and focusing accuracy 1.
How It Is Diagnosed
An eye doctor checks hyperopia with a refraction. This is the test that finds the glasses prescription.
Children often need dilating drops for the most accurate test. The drops relax the focusing muscle. This can uncover hidden farsightedness.
- Visual acuity. This checks how small the letters or pictures can be.
- Refraction. Lenses are tested to find the clearest focus.
- Eye alignment. The doctor checks for crossed eyes.
- Retina exam. A dilated exam checks eye health.
Treatment
Treatment depends on age, symptoms, and the strength of the prescription.
- Glasses. This is the most common treatment. Children may need full-time wear.
- Contact lenses. These can work well for teens and adults.
- Vision follow-up. Children with crossed eyes or lazy eye need closer care.
- Laser or lens surgery. Some adults choose surgery after the prescription is stable.
Research in children shows that uncorrected hyperopia can affect reading-related tasks during near work 2.
Common Questions About Hyperopia
Next Steps
- 1Book a comprehensive eye exam if reading is blurry or tiring.
- 2Schedule a pediatric eye exam if a child squints, closes one eye, or has an eye turn.
- 3Bring old glasses or contact lens prescriptions to the visit.
- 4Ask whether dilating drops are needed to find hidden farsightedness.
- 5Go to the emergency room for sudden vision loss, severe eye pain, or halos with nausea.
