Hi,
I have a question regarding a whiteness to the edges of the new lens in
my glasses.
I have just had the lens in my glasses replaced because the old ones
were scratched
so badly. This was done by my local optician who also previously sold
me the frame
and original lens. It is not a chain optican if that makes any
difference. Looking at
the new lens from the front they appear surrounded by a thin white line
which was
not present on the old lens. This appears to come from the channel
scored all around
the lens to allow for mounting in the frame. I queried this with the
optician and he has
polished the edges to remove the "frosty" effect a little, this
improved the appearance
a little, espesically looking at the lens from the side but the white
halo frosty effect is still
very much visible from the front. By the way, my frame is metal and the
frame only connects
to the top half of the lens. I'm not sure what the technical name for
this is ? There is
a cord thingy running around the groove in the lens to keep it in the
frame. The optitcian
said this was the standard way of doing this.
My question is :- is anyone in the trade familiar with this problem and
is it due to
a machine fault or the type of lens or the technician. He tells me the
machine was
recently serviced and I know the techician/optitcian has been there
quite a while. I
think he may have done the orignal glasses which were fine. I'm not
partitcularly happy
with the new lens because of this white edge effect although they are
perfect to look
through which perhaps is the most important thing. Ah vanity! Am I
stuck with this
effect or can any one give me ammuntion to come back to them on ?
Thanks very much for any help on this.

did he remove the lenses to polish the edges? sounds like grinding
powder trapped between the nylor line and the lens. have him pop them
out and buff the edges. if still too white, have him dip them in a lens
dye for a second or two.

If the lenses are polycarbonate, it can also be the burr inside the
groove. It can be removed by removing the lens and running a blade or
screwdriver tip inside the groove.
