I just phoned the optician where I last went for glasses and asked
about some 'safety spectacles' made up to the same prescription as my
current (reading) glasses for use when D-I-Y'ing.
They didn't have much idea what I was on about really! It seems strange
to me in our safety conscious society that something like this is hard
I'm *much* more likely to wear prescription safety glasses than
goggles or similar eye protection. I realise that safety spectacles
aren't as good as the best goggles etc. but they are still going to be
much better than the likely alternative.
Presumably most safety spectacles are paid for by businesses or other
workplaces and thus 'ordinary' opticians don't get to know much about
the last time I asked for those, about 5 years ago they came back with
lenses so thick and heavy my glasses kept sliding down my nose. I took
them back and got them changed for ordinary ones. I don't see why
toughened glass needs to be 2x thicker and heavier than the normal

The demand is very limited, given that most people are quite happy with
safety glasses that fit over their prescription glasses. Bolle stopped
making them a year or two ago and I don't know any other maker who does
prescription safety glasses.
I don't know the current regulations. But the normal plastic lens used in
specs are almost bullet proof and used to be considered an acceptable
alternative, especially if side guards are fitted.
Nobody uses glass in specs these days do they? It's fragile, heavy and
expensive. Plastic lens' need not be thick, they can be made with thin edges
(at extra cost). My right eye is -6 and the plastic lens is neither thick or
Just ask your optician for the specification of their plastic lens options.

I do. Whenever I buy new specs I always have to insist that 'yes' I
really do want glass lenses. At -8 every little helps to make the
lenses a little thinner.
One thing I find incredible is the rip off prices that the high street
opticians charge. I have found that Costco (yes not the first place
that you might think about buying specs) charge only about 1/3 to 1/2
the price of the high street shops for high specification lenses. The
quality of their workmanship is also superb compared to the high
PS: If you want to know why the high street opticians charge so much,
next time you are looking, ask how much the VAT is on your new specs
(it won't be 7/47ths of the total). You may be intrigued by how much
of the cost of the specs relates to the exempt supply of 'fitting'
(not the sight test) rather than the standard rated supply of the
specs themselves. Funnily enough they won't sell you the specs without
the assistant 'fitting' them.
One of the lenses shattered - the shards were long, thin, and very sharp,
and took a chunk out of my eyebrow, which needed a number of stitches to
repair - fortunately, the various bits of damage were just to my face,
narrowly missing the eye itself. Since then, I always get the most
impact-resistant lenses available. They cost quite a bit more, but I think
my sight is worth it.

In 36 years of spectical wearing (from age 7) I think I have only ever
broken two lenses. I think I sat on one pair a *very* long time ago
and the last time was when the slipped of my nose planning a bit of
wood and they landed on the top corner of a spade.
Glasses seem expensive full stop. I shall have to check out CostCo...
Trouble is I want a metal frame, comfort bridge, spring hinges and
large lenses, NOT tiddly pads and letterbox lenses...
Agreed, I've had plastic in the past and they do scratch very easyly.

SpecSavers do them
http://tinyurl.com/hkmd and click the Safety Eyewear link
The page seems targetted at employers to buy vouchers to give to
employees who redeem them at a SpecSavers shop but I see (no pun
intended) reason why you can't just go into SS and buy them.
Go to www.yell.com and look up optical goods wholesalers. These are the people
who opticians send your specs to to get the lenses made. Many years ago in the
days before MS Windows I used to have a friend whose business unit was next
door to one of these places. I popped in one day to see if they could mend the
broken bit of "fishing line" that held my lenses in. Everyone was wandering
around rather grumpily for some reason and the boss asked me if I happened to
know anything about computers. Turns out the pc that drove their lense grinder
had run out of disk space and refused to play ball but there were no unusually
big files on the disk that could be filling it up. So I had a look with chkdsk
and the disk was full of dummy FILExxxxx.chk files (for anyone old enough to
I'd come across this before with CAD applications. If you switch the pc off at
the mains without shutting it down properly first any temp files the programme
has created stay on disk as dummy files. I asked them how they switched theirs
off and sure enough they just unplugged it rather than closing the application
down properly. With many megabytes of dummy files deleted it all worked again
and the guy said I'd saved them a small fortune on getting the pc support bloke
out. On the strength of that I got my fishing line replaced and free lenses
whenever I wanted them so I used to just find the cheapest optician to do the
test and take the prescription into them for making up and fitting.
As for the lenses, they cost about a quid and come as huge round blanks big
enough for any frame and in all the various strengths. The CNC machine
digitises your frame shape and then grinds the lenses down to fit. Takes a few
minutes each and costs very little. Then the optician marks the price up by
several hundred percent for doing little more than putting your frames in the
post. The place I used is in Watford
Fairplay Optical Ltd

I'm sure they or anyone else local to you would be as happy to make your lenses
up as work for opticians for peanuts.
