Vision problems are common, so much so that they have become easily accommodated with the help of an optometrist. Patients with myopia can get clearer vision with prescription glasses and contact lenses. Surgical procedures for permanent vision correction are also available. Making an informed decision about vision correction for myopia starts with understanding the symptoms and causes.
With myopia, patients can see nearby objects clearly but not those in the distance, such as television screens or road signs. Therefore, myopia is more commonly known as nearsightedness. When the eyes are otherwise healthy, it is classified as simple myopia. There is also a variant known as pathological myopia, which develops due to degenerative changes in the retina.
Corrective lenses may help with both types of myopia. An optometrist can also provide treatments to manage the retinal degeneration behind pathological myopia.
It is common to be unaware that one has myopia because they are used to seeing that way, having had it since childhood or having developed it slowly over time. However, this can lead to problems while driving, during meetings, school, or leisure activities such as reading, watching movies, or playing sports. In addition, it can cause uncomfortable symptoms like headaches from eye strain. Per the National Eye Institute, other common signs and symptoms of myopia include:
An optometrist can diagnose patients with myopia through a routine eye examination. They will ask the patient to read a Snellen eye chart with various letters decreasing in size from top to bottom. If patients have issues reading any part of the chart, they will use a phoropter to create a custom prescription. A phoropter is an instrument that cycles through different lenses, revealing whether the patient has myopia or hyperopia (farsightedness).
Errors in how the cornea refracts light cause myopia. The Mayo Clinic states this refractive error occurs due to an oval-shaped eye or a steeply curved cornea. Thus, myopia can be genetic.
That said, a family history of myopia does not guarantee it. Rather, it makes a person predisposed to it. Environmental factors — such as spending too much time on the computer, using a smartphone, or reading — increase one’s likelihood of developing myopia.
Corrective lenses can accommodate myopia, providing clear vision whenever the patient wears them. However, surgical procedures designed to offer a more permanent solution for myopia are also available. Explore these myopia treatments in greater detail below.
Eyeglasses and contact lenses are corrective lenses that use a custom prescription created during an eye exam. Contact lenses require an additional exam to ensure the eyes can support them, primarily by testing for sufficient lubrication. The optometrist will measure the size of the cornea and then recommend soft, disposable, or extended-wear contacts accordingly.
Alternatively, eyeglasses do not require testing beyond the eye exam. Most optometrist offices have a wide selection of eyeglass frames, from masculine and feminine to unisex. An optician can help patients find frames that fit their unique style and eye care needs. For example, a higher prescription will likely need thicker frames to hold thick lenses, while wire-rimmed glasses are a good choice for patients with lower prescriptions.
Once frames are selected, the optician will fit them to the patient’s face. This primarily involves marking pupillary distance so the prescription lenses sit within the frame for optimal vision correction. It can take about two weeks to get prescription glasses back from the lab.
Corrective lenses are not the only way to get clearer vision. Patients with myopia may get permanent vision correction through surgery. While optometrists do not usually perform these surgeries themselves, they can recommend and discuss them. Examples include:
