Anti-polishing a lens

[EdgeOptical]

most of our labs will polish the edges if we ask for it or not... which is usually fine, except for today. We have a pt. that is getting glare and "white spots" from the lens edges when there are low over head lights.


does anyone know of a reasonable way to make the edges opaque again with out remaking them or anything like that? I colored the edges to hopefully cut down the glare coming through, but wondered if there was a better option.

we can use a fining pad - and seems to work nicely to scuff up the edges -
however - maybe a emery board will work for you - ?

We use fining pads too (the ones for poly work the fastest because they're rougher than the cr39 pads), and so far they've worked the best for taking off a polished edge and leaving a nice one behind without any deep scuff marks. See if your lab will send or sell you a roll of poly pads. We get ours from PSI: http://www.looktopsi.com/optical_sup...e_two_step.php and mainly use the MSF15-7 orange striped pads.

I also use a fining pad or 600 or 1200 grit emery paper. Just be sure to not use too much pressure or you will start sizing the lens smaller.

thats a great option, and we considered something similar.... i was just worried about the AR so i didnt want to be too rough with it.

we have a "marker" that makes the edges look polished, but i didnt know if there was a similar one to make them opaque.


thanks for all the quick input guys, i appreciate it

I use a first fine pad DAC PDR600, i think then a second fine pad the pinkish ones from DAC. I find it works well on all materials. I just cut a leaf off and stick it to my thumb and go to town.

If you don't have easy access to fining pads use an piece of 180 grit aluminum oxide sand paper. Cut a strip about 1" wide and a few inches long, wrap it around your finger and go to town. You can also use the stuff to frost a lens.
