eye glasses for myopia control
Single vision glasses offer a simple way to correct the blurred far vision for people with myopia. Research has revealed, though, that single vision lenses do not protect against myopia progression, which has led to development of special types of spectacle lenses (glasses) to slow and control progression of myopia.
How does myopia control eyeglasses slow near-sightedness?
When standard single vision glasses are worn to correct myopia, central vision is made clear but peripheral light rays are focused behind the retina. This appears to trigger the eye to grow towards where the peripheral image is focused, behind the retina, leading to accelerated eye growth. The principal of myopia control vision correction is to create the opposite profile, by making the peripheral light rays focus in front of the retina. This is type of optical profile instead creates a 'slow-down' signal for eye growth, to stop the retina moving further away from the peripheral light focus which is now in front of the retina. The result is that any slowing of eye growth will similarly slow progression of myopia.
