    Urgently I need help with Edging High prescription lenses

    Any one can help when I do edging high prescription lenses like -8.00 and up when I check lenses after edging in the lens meter I am getting the lenses either off axis or slip so the PD will be off or even more than that the segment height changed although I am using anti-slippage stickers applied to the front and back of lenses .Any solution to this urgent problem. Urgently I need help with Edging High prescription lenses. I appreciate any suggestions.

    Edging high prescription lenses can be challenging due to factors like lens thickness and curvature. To address issues like off-axis, slippage, and segment height changes, consider using specialized edging equipment, sturdy frames, and lens designs tailored for high prescriptions. If problems persist, consult an optician for adjustments or re-edging.

      You should have options in blocking pads, and edger settings that allow for a better grip or more pressure on the chuck. Sometimes that works, sometimes it's more of a headache than its worth. What works best for me is just to hand crib the lens to give your edger some relief. Just line up your decentration and trace the demo's or the frame. Then shave off as much as you can with a hand stone. Its saved me a lot of reorders

        I’ve done the same, except I used a bandsaw to cut off the excess. Bandsaws cut all plastics like butta.

            Optical24/7's technique is the best way to deal with slippage. I've been using a bandsaw to crib lenses for many, many years.
