Pardon me, but I thought that most specs/glasses had plastic lens/lenses anyway.
OK, I'm one of those with plastic lenses replacing my 'original' cataracts
and chose to have 'distance' sight for most things and 'reading' etc catered for with bits on my ordinary plain specs.
So a bit more from 'Lessons from a Lesser Lunacy' and I wear bifocal sunglasses after my cataract ops- in any bright conditions.
The reason is simple. I was painting a Spanish wall with white paint( as one does
) and went to bed. In the middle of the night( the wee wee hours
) and I was looking through two black squares! I sort of panicked a bit- thought Oh, my whatsit and woke my better half.
Happily, I wasn't going to be a candidate for 9 minutes at the local incinerator or having my plumbing further blown out or Black and Deckered
I had simply exposed my self(
) to such bright sun and reflections that come in Alpine snows and deserts.
So, I have passed the warning on- and so far it has been appreciated
Oh, in case I have wandered- I wear a pair of surgeons binoculars in the workshop
