Not strictly medical, but I noticed this group had posts about
spectacles/lenses.

Briefly - I have uniform starburst scratches on both lenses of my
glasses. The optician says they are scuff marks, I'm not convinced.
Just wondering if anyone knows if they could be caused by manufacturing
faults etc.

Detail:
I have some glasses about 2 years old with what I can best describe as
starburst scratches in the centre of BOTH lenses - to the point that
they need replacing. Each 'startburst' is approx 1cm across and has
numerous dots in the middle surrounded by straightish scratches/lines
for 360 degrees that form something like a startburst, spokes on a
wheel or petals on a flower, see:

http://www.ebun.org.uk/lens.html (The full circle cannot be seen owing
to the way the light falls)

They stop abruptly and form something like a circle.

The lenses are plastic, with anti glare coatings (and possibly others),
they are high index(?) as I'm quite short sighted and a good make from
what I always consider a good opticians. They were the most expensive
lenses I could have had. They have been cleaned every day following the
opticians advice, quick rinse under the tap, spray of lens cleaner and
a wipe from one side to the other with a cloth they supplied. I then
give each lens a light rub with the cloth to dry them.

The opticians say they are scuff marks or scratches that I have caused.
I've never placed them lens down, but I can imagine they will have been
scratched lightly from time to time as I wear them all the time and
play with my kids etc.

I feel that as the scratches are the same on each lens and quite
uniform and circular that they aren't 'natural' scratches (like the
other scratches on the picture above), could it be the coating breaking
up? Stress in the lens? Or something else?

Any thoughts welcome.

Thanks,

Miles.
