Recently arrived to market new spectacle lenses designed to prevent myopia progression.  The aim of this work was to analyze of most recent clinical trials evaluating different spectacle lenses  at level of myopia retention efficacy and also visual performance, accommodation facility and  binocular function in children.
A search was performed using PubmedCentral and including all randomized clinical trials  (RCT) that were found in search by “spectacle lenses to myopia control”. Results were filtered and  only the results from the last 10 years were included. Results including bifocals, orthokeratology,  atropine or progressive addition lenses (PALS) reports were excluded.  
Total of 4 types of lenses designed to prevent myopia progression were identified: Peripheral  Defocus Management (PDM) commercialized by CarlZeiss as MyoVision, Defocus Incorporated  Multiple Segments (DIMS) commercialized by Hoya as MiYOSMART, Highly Aspheric Lenslets (HAL)  commercialized by ESSILOR® as Stellest and Perifocal (PF) commercialized by INDO as SuperKid  Miofocal (Iberia) or FRAMETEC Perifocal (Germany). At this time, duration of studies varies between  1 (HAL) and 5 years (Perifocal). The efficacy in myopia retention determined by refractive error was  15%, 52%, 63% and 60% respectively using PMD, DIMS, HAL and PF. Not verified significant  differences in distance and near VA high contrast between DIMS, HAL and PF comparing Single Vision  (SV). Binocular function and accommodation not significantly varied with DIMS and HAL comparing  with SV.
Most recent and efficient spectacle lenses designed to avoid myopia progression reveals  positive tolerance and acceptance by children and demonstrated lower impact on both visual acuity  and contrast sensitivity. Although the levels of scientific evidence are limited, there are notable  contributions to preventing the progression of myopia with ophthalmic lenses designed for this  purpose.
