What Are Nearsightedness And Farsightedness?

Needing vision correction for nearsightedness (myopia) and farsightedness (hyperopia) is very common. According to studies by the American Optometric Association, almost 30% of people in the U.S. are affected by myopia, and nearly 60% of people have hyperopia.

Myopia is a vision impairment that causes challenges with or a lack of ability to make out things that are not close to the eye. This means that distant objects or images may seem fuzzy, or the patient might lack the ability to see them at all. Hyperopia results in the impaired ability to see objects that are at close range, for example, mobile devices or images. 

Hobbies like reading and even things like tweezing can be very challenging. Similar to myopia, farsightedness can range from mild to extreme and will often cause other undesired symptoms that can affect you on a daily basis. Luckily, we offer multiple treatment options to correct or reduce your nearsightedness and farsightedness.

At Wang Vision Institute, Dr. Ming Wang and his experienced team of eye surgeons, optometrists, and ophthalmologists can examine you for myopia and hyperopia and go over all your available treatment choices. Arrange your appointment at our Nashville, TN, office for a complete vision exam with one of our doctors and move one day closer to viewing the world more clearly than ever.

What Are The Symptoms of Myopia and Hyperopia?

Usually, the first definite indication of myopia is fuzzy vision when looking at things that are far away. Often, patients can also deal with other problems that stem from consistent squinting or eye fatigue. Eye strain, also known as eye fatigue or asthenopia, could cause aching or dry eyes. It might also cause light sensitivity or discomfort in the neck and shoulder muscles. Occasionally, people who already wear prescription lenses for myopia can notice these symptoms. They most likely mean that your eye prescription should be updated, so you need to plan an eye exam before long.

Those with hyperopia might not realize it until their near vision begins to be impaired. The inability to focus on items near the eyes is typically the most notable evidence of being farsighted. However, farsightedness that isn’t noticeable yet or has been neglected does typically cause eye fatigue, is also referred to as asthenopia. The extra strain on the eyes that comes from carrying out close-up tasks, for example, reading, playing video games, or using the computer, can cause migraines, burning and sore eyes, and stiffness in the shoulders and neck. Those who wear glasses or contacts for hyperopia but are still having these symptoms should set up an eye exam to find out whether their prescription should be altered.

What Causes Nearsightedness and Farsightedness?

Experts report that both myopia and hyperopia can be either genetic or caused by certain activities. The blurred vision that happens with nearsightedness and farsightedness is due to the abnormal shape of either the cornea or the eyeball. If the eyeball is a little elongated front to back, or when the cornea is too curved, the light entering the eye can't be aimed correctly onto the retina.

Usually, myopia begins to develop in young students, especially in students who are genetically predisposed. However, adults can also develop myopia from certain activities or other health issues. A few things that have been connected to myopia are high-focus reading and writing spanning extended periods of time (like in study or workplace contexts), not being outside, and, recently, spending prolonged periods focusing on mobile devices. Nearsightedness can also be a symptom of unmanaged blood sugar levels in patients with diabetes mellitus.

Most of the time, hyperopia already exists on the day of birth, but children can, over time, overcome their impairment as their eyes continue growing. This condition can be easily mixed up with presbyopia. Both affect near vision, but they are totally distinct conditions. Presbyopia is the name for impaired near vision due to the stiffening of the eye’s lens. It occurs as we age and is most common in people past 40 years of age.

How Are Myopia And Hyperopia Diagnosed?

During your eye exam for myopia and hyperopia in Nashville, TN, at Wang Vision Institute, Dr. Wang or a member of his team will conduct a full examination to check your overall eye health. Your assessment will incorporate common eyesight tests to look for any refractive vision issues, such as hyperopia and myopia. The tests used can detect both nearsightedness and farsightedness. These routine tests almost always include the patient demonstrating how precisely they can make out the letters on an eye chart, as well as a couple of tests to examine if light is arriving at the retinas correctly. Each acuity test is performed quickly and totally painless. If you are diagnosed with myopia or hyperopia, the optometrist will then run a few tests to create an appropriate prescription for your eyewear.

How Are Myopia And Hyperopia Treated?

Individuals who are told they have myopia or hyperopia have a handful of simple, effective treatment options available to suit their prescription and normal day-to-day routine. Dr. Wang most often prescribes eyeglasses or contact lenses to correct vision. The majority of patients opt to go with both options to accommodate their personal needs. Some patients might also consider laser vision correction surgery for life-changing results. Talk to Dr. Wang if you would like to have refractive surgery (like LASIK), and he will determine if you are a good candidate.
