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

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.
