Spectacle lens designs for myopia controlīifocal spectacle lenses were originally designed for people with near vision focus issues, and some children can need these lenses for eye muscle teaming problems. To learn more about myopia see our page What is myopia, and to learn more about myopia control read our article What is myopia control and why it's important. The good news is that there is now a large and growing body of evidence to support that myopia progression can be slowed down using specially designed spectacle lenses (glasses), contact lenses, ortho-k and atropine eye drops. Around half of teenagers reach stability of their myopia progression around age 16, 2 but this means half are still progressing, so ideally myopia control treatment should continue into early adulthood. Myopia control is also important in teenagers as their vision can still be worsening, albeit at a slower rate than in younger children. Myopia control is particularly important in children, because this is the stage in life when myopia is most likely to progress or worsen quickly. 'Myopia control' has become the increasingly adopted term to describe the use of treatments aimed to slow progression of myopia.
Research has revealed, though, that single vision lenses do not protect against myopia progression, 1 which has led to development of special types of spectacle lenses (glasses) to slow and control progression of myopia. Single vision glasses offer a simple way to correct the blurred far vision for people with myopia. Myopia causes blurred vision for far distance objects, but as myopia increases, the blur can start to be noticed even at arm's length or closer. What sort of glasses are prescribed for kids and teens with myopia? This article focuses on the technology of spectacle lenses, which are the key component of glasses which function to correct vision. The term 'glasses' is used commonly to describe the combination of spectacle frames and spectacle lenses. These have the far distance correction at the top of the lens, and a gradual change in power down to the near vision correction towards the bottom of the lens for reading.īifocal spectacles can be thought of as two pairs of glasses stuck together, with far vision correction above the visible line in the lenses, and reading vision correction below the visible line.Ĭhildren, teenagers young people sometimes need to wear multifocal or bifocal spectacle lenses to correct problems with eye focus and eye muscle coordination. Multifocal spectacle lenses include more than one focus power within the lens, and utilize eye movement across the lens for the wearer to be able to use the appropriate lens power. In this case, a different prescription for glasses is needed for far vision than for close up vision. This becomes limiting when people start to lose their ability to focus up close in their 40s, called presbyopia. Single vision lenses are simple to manufacture and widely available, making them an ideal solution for most vision correction problems.Ī problem with single vision glasses is that their fixed focus only allows them to correct for one single power.
Single vision glasses are the most commonly prescribed by optometrists and eye doctors, and used to correct myopia (shortsightedness), hyperopia (longsightedness) and astigmatism. What are the different types of lenses for glasses? Glasses offer a stable way to position a lens in front of the eye, which range from simple single vision lenses to complex lens designs that include multiple focus powers.
