Prescribing for the Progressing Myope with Astigmatism

Whilst each individual child has their own circumstances and situation to consider when prescribing myopia control, children with astigmatism present a unique set of challenges when selecting the best option for not only slowing down the progression of their axial growth, but also providing them with good vision.

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. Looking away from the optical centre of the lens (while keeping the vertex distance constant) also reduces …
