Myopia, or nearsightedness, is a condition where light that enters the eye does not focus on the retina, as it should for clear vision, but in front of the retina, causing distant objects to appear blurry while allowing near objects to be in focus. In other words, myopia occurs when the eyeball grows to be too long. Over 80 million children have been reported to be myopic worldwide, and rates continue to increase. Due to lack of access to adequate vision care in many parts of the world, uncorrected myopia has the potential to have considerable public health and socioeconomic impact.
Myopia is often diagnosed in childhood, typically between 8 and 12 years of age, and it can be an inherited condition, meaning that the likelihood of developing myopia increases if one or both parents are myopic. Additionally, rates of myopia are highest in East Asian and South Asian populations, with some studies reporting that up to 80-90% of Asian schoolchildren suffer from the condition.

Treatment for myopia has traditionally involved eyeglasses or contact lenses to improve vision. However, recent studies have indicated that addressing both the central and peripheral vision may help to reduce the growth rate of the eye, thus slowing down the progression of myopia. This philosophy was incorporated into the design of the MyoVision spectacle lens by Zeiss. The MyoVision lens uses a technology called Peripheral Vision Management, which allows for clear central vision and simultaneous movement of the peripheral image in front of the retina. Initial research has shown that this technique reduced the rate of progression of myopia by an average of 30% in East and Southeast Asian children between the ages of 6 and 12, with a parental history of myopia.
MyoVision lenses are thin and light, and appear no different than regular spectacle lenses. Please consult with your My Optometrist Calgary doctor to see if MyoVision lenses are right for your child.

Nikon is a company best known for its superior camera lenses. However, the same technology, materials, and wealth of optical design knowledge that allowed Nikon to revolutionize the field of photography have also been used to design and produce their premium eyeglass, or ophthalmic, lenses.
Nikon, founded in 1917, has a long and rich history of producing the highest quality optical products. In 1946, Nikon began manufacturing ophthalmic lenses, thus providing sharper, more detailed vision to millions of people around the world.
Nikon’s ophthalmic lenses consistently deliver the latest in optical technology and design, and the superior clarity and optics that people have come to expect. Nikon is able to maintain this standard through their commitment to cutting-edge design, the use of premium high-index materials, and the application of high-quality lens coatings to maximize optical performance and durability.
Because of this tradition of excellence, Nikon’s ophthalmic products have long been an integral part of the lenses that My Optometrist Calgary offers.
