Providing spectacle correction is one of the cornerstones of primary eye care, and myopia controlling spectacles can both correct and control myopia. Here we explore the current myopia controlling spectacle lenses which have or are being commercialized, for which peer-reviewed publications are available – their design, presumed mechanism and comparative efficacy.
Here we explore an overview of spectacle prescribing for myopia management – from when to use single vision, to progressive and bifocal designs, new myopia control specific designs, and whether to fully or under-correct.
There’s a little more to think about in the important role spectacle lenses play in myopia management. Even if we prescribe contact lenses, our young myopes are most likely to need a back up spectacle lens option. Children prescribed atropine will need the best spectacle lens prescribed for them to minimise the impact of any side effects.
Are progressive addition lenses and bifocals created equal for myopia control? When do they work and when do spectacles have minimal efficacy? How should we pick which lens type to prescribe, and what’s on the horizon for our non-contact lens wearing young myopes?
Changing a myope from spectacle to contact lens wear can alter their binocular vision (BV) function. The myope reading through their spectacles experiences base-in prism at near, as demonstrated in the image above, which moves the image further away and decreases vergence demand.
