What Is Hyperopia?
Hyperopia, or farsightedness, is when you see things that are far away better than things that are up close. Your eyes focus better on distant objects than on nearby ones.
The cornea, the clear outer layer of your eye, and the lens focus images directly on the surface of your retina, which lines the back of your eye. If your eye is too short, or the power to focus is too weak, the image will go to the wrong place, behind your retina. That’s what makes things look blurry.
You may have:
- Trouble focusing on nearby objects
- Blurry vision
- Eye strain
- Fatigue or headache after you do a close-up task such as reading
If you have these symptoms when you wear glasses or contacts, you may need a new prescription.
All it takes to diagnose farsightedness is a basic eye exam. Your doctor will have you read a chart across the room. If that test shows hyperopia, they’ll use a device called a retinoscope to look at how light reflects off your retina. They’ll also use a phoropter – a testing device -- to help them decide on the best prescription for glasses or contacts.
Adult eye exams
The American Academy of Ophthalmology says adults who haven’t had vision problems should get an eye exam at age 40. Have eye tests every 2 to 4 years between ages 40 and 54. Between 55 and 64, get tested every 1 to 3 years. If you’re 65 and older, get tested every 1 to 2 years.
If you have diabetes, high blood pressure, or a family history of eye disease, don’t wait until you’re 40 to have an eye exam. Your doctor also might want you to come in more often.
Children’s eye exams
Experts recommend that infants have their eye health checked when they’re between 6 months and 1 year old. Children should also have vision tests between ages 3 and 3½, before they start school, and every 1 to 2 years after.
