Currently,　there　are　many　issues　with　customizing　nearsighted　spectacles.　Most　designs　are　based　on　a　universal　standard　of　25　degrees,　and　the　frames　are　difficult　to　customize　to　fit　the　wearer＇s　face.　This　paper　introduces　a　method　for　utilizing　3D　printing　to　manufacture　entire　spectacles,　known　as　additive　manufacturing　(AM),　for　parametric　customization.　Firstly,　a　user-friendly　human-machine　parameter　platform　is　obtained　through　secondary　development　in　SolidWorks　using　Python.　The　customization　parameters　of　spectacles　can　be　easily　implemented　on　this　platform.　Spectacles＇　parametric　customization　mainly　includes　feature　scanning,　parametric　platform　modeling,　and　spectacles　manufacturing.　In　addition,　after　designing　the　model,　it　is　manufactured　through　3D　printing.　After　passing　the　spectacles＇　quality　testing,　their　appearance,　size　accuracy,　and　light　transmittance　all　meet　the　required　standards.　Additionally,　at　initial　velocities　of　10m/s　and　20m/s,　the　maximum　allowable　stress　of　the　glasses　meets　the　following　requirements:　σ≤103MPa,　and　the　deformation　also　meets　＇l≤0.5mm.　The　parametrically　customized　spectacles　designed　in　this　study　meet　the　quality　standards.　©　Published　under　licence　by　IOP　Publishing　Ltd.
