SUBSCRIBE IF YOU WANT THIS MACHINE ?

This machine costs around $300 and actually takes real skill to use ? Inside, tiny glass beads are heated up to nearly 350 degrees, creating a controlled heating system for eyewear frames ?? If the frame stays in too long, it can easily warp or get damaged, so the optician carefully moves it through the beads to distribute heat evenly. Once the material becomes flexible enough, the lenses are inserted, and then the frame is left to cool and harden back into its final shape. It’s a precise process that shows how much craftsmanship goes into making perfect glasses ?✨ Credit to: Respective Owner #shorts #viral
