You’ve probably heard the term myopia before. But what exactly does myopia mean? Is it a disease? How should I cure or treat myopia? If I wear glasses, will it make my myopia even worse? Let’s cover everything you need to know about what it means to have myopia.
The Classic Definition of Myopia
Classically defined myopia is a vision condition where you will see objects up close much more clearly than objects you see far away. Another word to describe myopia is nearsightedness and these words are used interchangeably at times. Myopia happens when the eyeball is too long or if the front part of the eye called the cornea is too steep. The majority of the time, however, myopia occurs because the eyeball size, or the axial length, is too large. When this happens, a clear image doesn’t land far enough back onto the back of the eye called the retina.
Recent research shows that myopia affects more than 42 percent of the United States population. This number has been increasing every year at epidemic levels worldwide as we expect half of the world to have myopia by 2050. While many scientists initially believed that genetics were the primary cause for developing myopia, we now know that the environment in which we grow up can tremendously impact the level of myopia we have as adults. Increased digital device usage, lack of outdoor activity, and too much near work have been associated with developing high levels of myopia.
The Dangers of Having Myopia
There are different types of myopia as well. If a child develops myopia at a young age, we know that they are at higher risk of developing high myopia and even pathological levels of myopia. High levels of myopia can lead to an increased risk for diseases of the eye such as retinal detachments, glaucoma, and myopic maculopathy. Unfortunately, those diseases can all lead to permanent vision loss. These life-altering diseases are another layer of danger besides the obvious need for optical correction in glasses or contact lenses in order to see clearly.
When you have pathological or degenerative myopia, other signs can form on your eyes that your eye doctor needs to monitor over time. Lattice degeneration and lacquer cracks of the retina all show signs that the retina is under duress because the eyeball has grown excessively long. Ask your doctor about these signs and other ones such as a tilted optic nerve head disc and choroidal neovascularization that happen exponentially higher in cases of extremely high levels of myopia.
What are the Best Ways to Treat Myopia?
The best treatment is to first prevent myopia if possible. More research is being conducted in this area, but as a general rule, eye doctors are encouraging at least two hours of outdoor activity per day. More outdoor activities under natural sunlight have been associated with a lower risk of developing myopia in the first place. If your children have to do intense studying or reading, it is recommended to do as much reading as possible when the sun has set versus reading during the day.
Regular checkups with your eye doctor to diagnose myopia as early as possible is also critical. By catching myopia at an early age, there can be many different types of interventions to prevent myopia from worsening. Myopia typically begins in school-aged children and can worsen until the leveling out usually in your mid-twenties.
As far as the visual component is concerned, usually, a pair of glasses or contact lenses are sufficient. Once the eyes have stopped growing, refractive surgery procedures can be employed as well. But keep in mind that simply correcting your vision will not stop your eyes from getting worse. The root cause of myopia, an eyeball that continues to grow excessively long during our youth, needs to be addressed.
Special pharmaceutical agents such as atropine have been shown to slow down the progression of myopia considerably. Special contacts such as orthokeratology lenses worn at night are effective as well. Even soft contact lenses and glasses designed with special optics different from the traditional pair of glasses can be effective to slow down the rate of myopic progression.
Myopia Roundup
Regardless of your age or background, it is important to get educated about myopia because it is a widespread disease of the eye. Seeing your eye doctor or chart a proper course of action to prevent or treat myopia is incumbent on every parent in this new digital age. It is not just the digital age as well, results coming from studies of children after the COVID year of 2020 give strong evidence that the environment that COVID induced with social distancing may be causing the largest spike in myopia among children we’ve ever seen. Myopia is now viewed as a disease worth treating
Treehouse Eyes Can Help Prevent Myopia Progression
The good news is we help prevent or slow down myopia progression in kids—just like yours—so they can have their best shot at academic and social success! Above are four of the best ways we treat myopic progression once your child has been diagnosed with myopia. Orthokeratology involves reshaping the eye gently with a contact lens while sleeping. Atropine involves an eye drop that can signal the eye to grow a little slower. Custom soft multifocal lenses are worn during the day. And even specially designed glasses are on the horizon to improve the progression of myopia.
The Treehouse Eyes eye doctors use state-of-the-art equipment to develop a personalized treatment plan for your child. Our non-invasive treatments include customized contact lenses and special prescription eye drops. Moreover, data shows that our patent-pending Treehouse Vision System® treatment plan can decrease myopia progression by 78 percent.
