What is Myopia
Myopia is also known as short-sight, and is where things are blurry in the distance. It is becoming more common in children however, especially with the increase in use of computers and smartphones, placing ever increasing demands on the visual sysytem. It has been shown that increases in myopia are correlated with increases in the axial length of the eyeball. Ongoing long-term studies have shown that through various vision correcting methods, the rate of lengthening in the myopic eye of children can be slowed down, leading to a slower progression of myopia . If myopia is left unchecked, other than requiring stronger corrective lenses, there is an increase in risk of certain sight threatening eye conditions such as retinal detachment, myopic macular degeneration and glaucoma, as they are linked with high levels of myopia.
What can be done about it
By acting early, prevention of increased myopia is an effective solution. Various optical solutions will not only correct a childs eyesight, but also provide a protective effect in the progression of myopia.
1. Multifocal Contact Lenses
There now exist two CE approved multifocal soft contact lenses in the UK for myopia control. The Coopervison MiSight and the VTI NaturalVue. We provide the MiSight daily disposable lens as an option in Myopia management.
2. Orthokeratology (Ortho-K)
Orthokeratology (Ortho-K) involves wearing a custom designed and manufactured contact lens at night. The gentle corneal reshaping process not only corrects myopia (short sight) but also manages myopia progression. We have been providing Ortho-K lenses (known by us as Eyedream) for many years, with continuing success in attaining good eyesight and myopia control.
2. Myopia Management Spectacle Lenses
The Miyosmart from Hoya is a newspectacle lens proven to reduce the progression of myopia in children. Utilising the patented Defocus Incorporated Multiple Segments (DIMS) technology, the lens looks like a conventional single vision spectacle lens. However, the array of small lenslets in the lens periphery are what make the lens so effective in slowing down myopic progression.
