Highly Aspherical Lenslet (HAL) and Binocular Vision (BV) Disorders [HALT X(T) Study]

Summary
Assess the effect and changes of eye misalignment (strabismus) with myopia control glasses Assess the efficacy of myopia control glasses on childhood myopia progression in children with strabismus due to the uncertainty clinicians face when prescribing myopia control glasses to these strabismic children

HAL lenses for children with strabismus
It has been shown that peripheral segmented defocus spectacles can slow myopia progression. The Essilor® Stellest™ lens has been designed with an exclusive and pioneering technology called HALT (Highly Aspherical Lenslet Target). The HALT technology is made of a constellation of 1,021 invisible lenslets. This constellation creates a signal in front of the retina that acts as a shield against eye elongation and, therefore, myopia progression. Studies suggest that children are tolerable against these glasses, and the lenses can slow down myopia progression by 67% on average, compared to single vision lenses, when worn 12 hours a day. It can be considered as one of the best available myopia control spectacle lens designs, being superior to progressive addition and bifocal lenses.
