Myopia, also called nearsightedness, occurs when the eye changes shape from a sphere into more of an ellipse that is elongated from front to back. Normally, the lens of the eye focuses images on the retina, but when the eye is elongated images are focused in front of the retina instead. This is referred to as a refractive error. As a result, near vision stays clear but distance vision becomes weak and blurred. For example, if you have myopia, you may be able to read a book or see a computer screen well, but you will have difficulty seeing objects that are farther away, such as street signs.
Nearsightedness, which is an eye focusing disorder and not an eye disease, must be evaluated and treated by a qualified eye doctor. Generally, the treatment options for nearsightedness involve eyeglasses, contact lenses, and refractive surgery. Our optometrists at Browz Eyeware, in Calgary, AB, are experienced with myopia diagnosis and we’ll recommend the most effective treatment for sharp vision.
Causes of Myopia
The precise cause of nearsightedness remains unknown; scientists have not been able to determine with certainty what leads to the eyeball growing too long. Genetic risk factors definitely play a role, as do environmental causes – such as not spending enough time outside and longer amounts of time spent doing near tasks (computer use, reading, and writing). Some theories assert this is because natural sunlight helps with proper eye development, while other opinions claim that it is because normal eye development depends upon gazing off into the distance for sufficient childhood time.
Symptoms of Myopia
Typically, people with untreated myopia experience headaches, eye fatigue, squinting to see clearly, and trouble seeing objects in the distance. Kids may complain that they can’t see the classroom board. If you experience any of these symptoms, we encourage you to visit our Browz Eyeware optometrist for an eye exam in Calgary, AB.
During a comprehensive eye exam in Calgary, AB, our eye doctor will test your visual acuity and inspect your eye health. If you have myopia, we will detect the signs that indicate this refractive error. Our office is outfitted with various tools, such as a phoropter and retinoscope, that assist with myopia diagnosis and figuring out your precise vision prescription.
Treatment for Myopia
There is no singular “best” method for correcting myopia. Our eye doctor will discuss the available treatments with you to decide which one satisfies your lifestyle, eye health, and visual needs. Nearsightedness can be corrected in a few different ways:
1. Prescription Eyewear
The most common way to treat myopia is by prescribing eyeglasses or contact lenses. Both of these types of eyewear compensate for the shape of your eye and refocus light correctly onto the retina. Our eye doctors will review the pros and cons of each option with you, so you can make an informed decision about whether glasses or contacts are best suited for your needs.
2. Refractive Surgery
The eye’s optic error typically stabilizes after adolescence. At this point, refractive surgery is a popular option for correcting myopia. LASIK and PRK are the most well known versions of refractive surgery, both of which reshape the cornea to focus light on the retina more efficiently.
3. Orthokeratology/Ortho-k Lenses
Orthokeratology describes the process of wearing rigid gas permeable contacts while you sleep in order to reshape your cornea. These ortho-k lenses gently flatten the cornea and eliminate refractive error. In the morning, you remove the lenses to see clearly – without nearsightedness during the daytime. The effects are temporary however, which is why you need to wear ortho-k lenses nightly to maintain sharp vision.
