Myopia control efficacy over three years with highly aspherical lenslet (HAL) spectacle lenses

This 1-yr extension of a previous 2-yr clinical trial investigated myopia control efficacy of highly aspherical lenslet (HAL) spectacle lenses for children wearing them for a further year and for children switching to HAL after wearing slightly aspherical lenslet (SAL) or single vision lenses. HAL design lenses were able to provide or maintain a myopia slowing effect for all wearers.

Combining DIMS spectacle lenses with atropine 0.01% in European children

This prospective observational study found that DIMS spectacle lenses, atropine 0.01% and the combination of the two all showed robust efficacy for myopia control in European children. The combination treatment showed slightly better refractive control than the mono-therapies, but axial length growth was similar in all treatment groups.

What role do accommodation and binocular vision issues play in eyestrain symptoms?

While 80% of pre-presbyopic adults with Digital Eye Strain symptoms preferred reading with low-addition lenses, the improvement in reading speed was generally small and did not appear to correlate with specific accommodation or binocular vision dysfunctions. In the 8% who showed a significant improvement in reading rate of at least 15%, a majority showed reduced accommodation amplitude.

The effect of online learning on myopia progression

By using a wearable device to objectively monitor visual behaviour, this study found progression in young myopic children was correlated with less time outdoors, more time working at near for online learning and less time spent wearing their glasses.

Myopia control and no rebound with Highly Aspherical Lenslet spectacles

This cross-over study investigated children wearing highly aspherical lenslet (HAL) spectacle lenses versus single vision spectacles over three six-month periods. The HAL lenses showed consistent myopia control efficacy and no rebound effect when discontinued over one of the six-month periods.
