The esophoric myope and contact lenses

When it comes to contact lens corrections for young myopes, the impact of orthokeratology (OK) and multifocal soft contact lenses (MFSCL) on binocular vision is pertinent to visual comfort and understanding mechanisms of myopia progression and control. Oliver’s story Oliver, age 10, was referred with a history of fast, recent myopia progression. His mother was R&L -7.00 and he was …

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 …

Progressive vs bifocal spectacles – which is best?

Podcast summary: Are progressive addition lenses and bifocals created equal for myopia control? How should we pick which lens type to prescribe, and what’s on the horizon for our non-contact lens wearing young myopes? Progressive addition lens (PAL) studies for myopia control show negligible results when single adds are applied to all children, however when applied to children with esophoria …
