The next generation – DIMS and H.A.L.T. technology spectacle lenses for myopia control

The newest myopia controlling spectacles can both correct and control myopia as effectively as contact lens options. How do Defocus Incorporated Multiple Segments (DIMS) and HIghly Aspherical Lenslet Target (H.A.L.T.) technology spectacle lenses work? Here we investigate and compare their design, presumed mechanism and comparative efficacy for myopia control, based on published research.

Spectacle Lenses for Myopia Control Part 3: new designs and latest studies

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.

When to prescribe spectacles for myopia control

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.

Spectacle lenses for myopia control Part 2: Back ups and dispensing

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.

Specs to contacts – what happens to BV?

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.
