Hyperopia, or farsightedness, is a common vision problem, affecting about a fourth of the population. People with hyperopia can see distant objects very well, but have difficulty focusing on objects that are up close. The condition is sometimes referred to as “hypermetropia” rather than hyperopia.
Hyperopia symptoms
Farsighted people sometimes have headaches or eye strain and may squint or feel fatigued when performing work at close range. If you get these symptoms while wearing your eyeglasses or contact lenses, you may need an eye exam and a new prescription.

What causes hyperopia/hypermetropia?
Watch this video on what causes blurry vision and how we can correct it.
This vision problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. The eyeball of a farsighted person is shorter than normal.
Many children are born farsighted, and some of them “outgrow” it as the eyeball lengthens with normal growth.
Sometimes people confuse hyperopia with presbyopia, which also causes near vision problems but for different reasons.
Hyperopia treatment
Farsightedness can be corrected with glasses or contact lenses to change the way light rays bend into the eyes.
If your glasses or contact lens prescription begins with plus numbers, like +2.50, you are farsighted.
You may need to wear your glasses or contacts all the time or only when reading, working on a computer or doing other close-up work.
When selecting eyeglasses for the correction of farsightedness, choose aspheric high-index lenses — especially for stronger prescriptions. These lenses are thinner, lighter, and have a slimmer, more attractive profile. Aspheric lenses also reduce the magnified “bug-eye” appearance eyeglasses for hyperopia often cause.
Be aware, though, that high-index aspheric lenses reflect more light than standard plastic lenses. For the best comfort and appearance, make sure the lenses include anti-reflective coating, which eliminates distracting lens reflections.
High-index aspheric lenses for children should be made of lightweight polycarbonate lens material for superior comfort and impact resistance.
Also, photochromic lenses that automatically darken in response to sunlight are highly recommended for kids and anyone who spends a significant amount of time outdoors.
Refractive surgery, such as LASIK or CK, is another option for correcting hyperopia. Surgery may reduce or eliminate your need to wear glasses or contact lenses.
Investigational procedures involving corneal implants may be a future option for correcting hyperopia.
Myopia (also called nearsightedness) is the most common cause of impaired vision in people under age 40. In recent years, its prevalence is growing at an alarming rate.
Globally, research suggests that in the year 2000, roughly 25 percent of the world’s population was nearsighted but by the year 2050, it’s expected that roughly half the people on the planet will be myopic.
Myopia symptoms
If you are nearsighted, you will have difficulty reading road signs and seeing distant objects clearly, but will be able to see well for close-up tasks such as reading and computer use.
Other signs and symptoms of myopia include squinting, eye strain and headaches. Feeling fatigued when driving or playing sports also can be a symptom of uncorrected nearsightedness.
If you experience these signs or symptoms while wearing your glasses or contact lenses, schedule an eye exam with your optometrist or ophthalmologist to see if you need a stronger prescription.
Myopia occurs when the eyeball is too long, relative to the focusing power of the cornea and lens of the eye. This causes light rays to focus at a point in front of the retina, rather than directly on its surface.
Nearsightedness can also be caused by the cornea and/or lens being too curved for the length of the eyeball. In some cases, myopia occurs due to a combination of these factors.
Myopia typically begins in childhood, and you may have a higher risk if your parents are nearsighted. In most cases, nearsightedness stabilizes in early adulthood but sometimes it continues to progress with age.
Depending on the degree of your myopia, you may need to wear your glasses or contact lenses all the time or only when you need very clear distance vision, like when driving, seeing a chalkboard or watching a movie.
Good choices for eyeglass lenses for nearsightedness include high-index lenses (for thinner, lighter glasses) and lenses with anti-reflective coating. Also, consider photochromic lenses to protect your eyes from UV rays and high-energy blue light and to reduce the need for a separate pair of prescription sunglasses outdoors.
If you’re nearsighted, the first number (“sphere”) on your eyeglasses prescription or contact lens prescription will be preceded by a minus sign (–). The higher the number, the more nearsighted you are.
Refractive surgery can reduce or even eliminate your need for glasses or contacts. The most common procedures are performed with an excimer laser.
In PRK the laser removes a layer of corneal tissue, which flattens the cornea and allows light rays to focus more accurately on the retina.
In LASIK — the most common refractive procedure — a thin flap is created on the surface of the cornea, a laser removes some corneal tissue, and then the flap is returned to its original position

In LASIK — the most common refractive procedure — a thin flap is created on the surface of the cornea, a laser removes some corneal tissue, and then the flap is returned to its original position.
Then there’s orthokeratology a non-surgical procedure where you wear special rigid gas permeable (RGP or GP) contact lenses at night that reshape your cornea while you sleep. When you remove the lenses in the morning, your cornea temporarily retains the new shape, so you can see clearly during the day without glasses or contact lenses.
Orthokeratology and a related GP contact lens procedure called corneal refractive therapy (CRT) have been proven effective at temporarily correcting mild to moderate amounts of myopia. Both procedures are good alternatives to surgery for individuals who are too young for LASIK or are not good candidates for refractive surgery for other reasons.
Implantable lenses known as phakic IOLs another surgical option for correcting nearsightedness, particularly for individuals with high amounts of myopia or thinner-than-normal corneas that could increase their risk of complications from LASIK or other laser vision correction procedures.
Phakic IOLs work like contact lenses, except they are surgically placed within the eye and typically are permanent, which means no maintenance is needed. Unlike IOLs used in cataract surgery, phakic IOLs do not replace the eye’s natural lens, which is left intact.
Controlling myopia
With more people becoming nearsighted, there is a lot of interest in finding ways to control the progression of myopia in childhood.
A number of different techniques have been tried — including fitting children with bifocals, progressive lenses and gas permeable contact lenses. All of these have delivered mixed results.
Recent clinical trials showed that low-dose atropine eye drops could slow myopia progression in school-age children, with significantly fewer side effects compared with higher concentrations.
Some kids, though, don’t respond well to atropine drops.
A dual-focus daily disposable contact lens decreased the progression rate of myopia in children between 8 and 12 years old when compared to a single vision lens, according to a study presented in 2017 at the American Academy of Optometry meeting.
The specially designed multifocal lenses reduced myopia progression by 59 percent at one year, 54 percent at two years and 52 at three years, compared with the myopia progression experienced by children who wore conventional contact lenses.
“There were good correlations between change in refractive error and change in eyeball growth,” said Paul Chamberlain, who presented the research and is senior manager of clinical research at CooperVision.
Degenerative myopia
In most cases, nearsightedness is simply a minor inconvenience and poses little or no risk to the health of the eye. But sometimes myopia can be so progressive and severe it is considered a degenerative condition.
Degenerative myopia (also called malignant or pathological myopia) is a relatively rare condition that is believed to be hereditary and usually begins in early childhood. About 2 percent of Americans are afflicted, and degenerative myopia is a leading cause of legal blindness.
In malignant myopia, the elongation of the eyeball can occur rapidly, leading to a quick and severe progression of myopia and loss of vision. People with this condition have a significantly increased risk of retinal detachment and other degenerative changes in the back of the eye (such as bleeding in the eye from abnormal blood vessel growth).
Degenerative myopia also may increase the risk of cataracts.
See your doctor: If you are having trouble seeing near objects or find you are holding books (or your smartphone) farther away to better make out the words, you should see your eye doctor. Nearsightedness can be treated and in some cases slowed in children.

Glaucoma is a condition that damages your eye‘s optic nerve. It gets worse over time. It’s often linked to a buildup of pressure inside your eye. Glaucoma tends to run in families. You usually don’t get it until later in life.
The increased pressure in your eye, called intraocular pressure, can damage your optic nerve, which sends images to your brain. If the damage worsens, glaucoma can cause permanent vision loss or even total blindness within a few years.
Most people with glaucoma have no early symptoms or pain. Visit your eye doctor regularly so they can diagnose and treat glaucoma before you have long-term vision loss.
If you lose vision, it can’t be brought back. But lowering eye pressure can help you keep the sight you have. Most people with glaucoma who follow their treatment plan and have regular eye exams are able to keep their vision.
Glaucoma Causes
The fluid inside your eye, called aqueous humor, usually flows out of your eye through a mesh-like channel. If this channel gets blocked, the liquid builds up. Sometimes, experts don’t know what causes this blockage. But it can be inherited, meaning it’s passed from parents to children.
Less-common causes of glaucoma include a blunt or chemical injury to your eye, severe eye infection, blocked blood vessels inside your eye, and inflammatory conditions. It’s rare, but eye surgery to correct another condition can sometimes bring it on. It usually affects both eyes, but it may be worse in one than the other.

Glaucoma Risk Factors
It mostly affects adults over 40, but young adults, children, and even infants can have it. African Americans tend to get it more often, when they’re younger, and with more vision loss.
You’re more likely to get it if you:
Are of African American, Irish, Russian, Japanese, Hispanic, Inuit, or Scandinavian descent
Have high blood pressure, heart disease, diabetes, or sickle cell anemia
Have high eye pressure
Are nearsighted or farsighted
Types of Glaucoma
There are two main kinds:
Open-angle glaucoma. This is the most common type. Your doctor may also call it wide-angle glaucoma. The drain structure in your eye (called the trabecular meshwork) looks fine, but fluid doesn’t flow out like it should.
Angle-closure glaucoma. This is more common in Asia. You may also hear it called acute or chronic angle-closure or narrow-angle glaucoma. Your eye doesn’t drain like it should because the drain space between your iris and cornea becomes too narrow. This can cause a sudden buildup of pressure in your eye. It’s also linked to farsightedness and cataracts, a clouding of the lens inside your eye.

Less common types of glaucoma include:
Secondary glaucoma. This is when another condition, like cataracts or diabetes, causes added pressure in your eye.
Normal-tension glaucoma. This is when you have blind spots in your vision or your optic nerve is damaged even though your eye pressure is within the average range. Some experts say it’s a form of open-angle glaucoma.
Pigmentary glaucoma. With this form, tiny bits of pigment from your iris, the colored part of your eye, get into the fluid inside your eye and clog the drainage canals.
Glaucoma Symptoms
Most people with open-angle glaucoma don’t have symptoms. If symptoms do develop, it’s usually late in the disease. That’s why glaucoma is often called the “sneak thief of vision.” The main sign is usually a loss of side, or peripheral, vision.
Symptoms of angle-closure glaucoma usually come on faster and are more obvious. Damage can happen quickly. If you have any of these symptoms, get medical care right away:
Glaucoma tests are painless and don’t take long. Your eye doctor will test your vision. They’ll use drops to widen (dilate) your pupils and examine your eyes.
They’ll check your optic nerve for signs of glaucoma. They may take photographs so they can spot changes at your next visit. They’ll do a test called tonometry to check your eye pressure. They may also do a visual field test to see if you’ve lost peripheral vision.
Glaucoma Treatment
Your doctor may use prescription eye drops, oral medications, laser surgery, or microsurgery to lower pressure in your eye.
Eye drops. These either lower the creation of fluid in your eye or increase its flow out, lowering eye pressure. Side effects include allergies, redness, stinging, blurred vision, and irritated eyes. Some glaucoma drugs may affect your heart and lungs. Be sure to tell your doctor about any other medications you’re taking or are allergic to.
Oral medication. Your doctor might also prescribe medication for you to take by mouth, such as a beta-blocker or a carbonic anhydrase inhibitor. These drugs can improve drainage or slow the creation of fluid in your eye.

Laser surgery. This procedure can slightly raise the flow of fluid from your eye if you have open-angle glaucoma. It can stop fluid blockage if you have angle-closure glaucoma. Procedures include:
Trabeculoplasty. This opens the drainage area.
Iridotomy. This makes a tiny hole in your iris to let fluid flow more freely.
Cyclophotocoagulation. This treats areas of the middle layer of your eye to lower fluid production.
Microsurgery. In a procedure called a trabeculectomy, your doctor creates a new channel to drain the fluid and ease eye pressure. This form of surgery may need to be done more than once. Your doctor might implant a tube to help drain fluid. This surgery can cause temporary or permanent vision loss, as well as bleeding or infection.
Open-angle glaucoma is most often treated with combinations of eye drops, laser trabeculoplasty, and microsurgery. Doctors tend to start with medications, but early laser surgery or microsurgery could work better for some people.
Infant or congenital glaucoma — meaning you are born with it — is usually treated with surgery because the cause is a problem with your drainage system.

Glaucoma Prevention
You can’t prevent glaucoma. But if you find it early, you can lower your risk of eye damage. These steps may help protect your vision:
Have regular eye exams. The sooner your doctor spots the signs of glaucoma, the sooner you can start treatment. If you’re over age 40 and have a family history of the disease, get a complete eye exam from an eye doctor every 1 to 2 years. If you have health problems like diabetes or are at risk of other eye diseases, you may need to go more often.
Learn your family history. Ask your relatives whether any of them have been diagnosed with glaucoma.
Follow your doctor’s instructions. If they find that you have high eye pressure, they might give you eye drops to prevent glaucoma.
Exercise. Moderate activity like walking or jogging at least three times a week might help lower eye pressure.
Protect your eyes. Use protective eyewear when playing sports or working on home improvement projects.
Inside our eyes, we have a natural lens. The lens bends (refracts) light rays that come into the eye to help us see. The lens should be clear, like the top lens in the illustration.
Vision Problems with Cataracts
If you have a cataract, your lens has become cloudy, like the bottom lens in the illustration. It is like looking through a foggy or dusty car windshield. Things look blurry, hazy or less colorful with a cataract.
The top lens is a clear, natural lens. The bottom lens shows clouding by cataract.
What Are the Symptoms of Cataracts?
Here are some vision changes you may notice if you have a cataract:
Aging is the most common cause. This is due to normal eye changes that happen starting around age 40. That is when normal proteins in the lens start to break down. This is what causes the lens to get cloudy. People over age 60 usually start to have some clouding of their lenses. However, vision problems may not happen until years later.
Other reasons you may get cataracts include:
having parents, brothers, sisters, or other family members who have cataracts
using certain medications such as corticosteroids, which may cause early formation of cataracts.
Most age-related cataracts develop gradually. Other cataracts can develop more quickly, such as those in younger people or those in people with diabetes. Doctors cannot predict how quickly a person’s cataract will develop.
You may be able to slow down your development of cataracts.
Protecting your eyes from sunlight is the best way to do this. Wear sunglasses that screen out the sun’s ultraviolet (UV) light rays. You may also wear regular eyeglasses that have a clear, anti-UV coating. Talk with your eye doctor to learn more.
