Re: Chemical nastiness (poke in eye/contacts)

[David Ross <dr@xxxxxxxxxxxxxxxxxxxxxxx>]

I've worn soft contacts at various times over the years. They're
wonderful inventions. But the reason I'm not wearing them now and in the
past have had to stop is that I'm in an environment that will kill my
vision if I keep wearing them.

Soft contacts HAVE to be gas and fluid permeable to allow air and tears
to get to the eye. Which as a practical mater makes them sponges for
both gases and liquids. When in an environment where vapors or dust
tends to be common then you should get them out fast. Otherwise they'll
absorb the vapors and hold them against your eye. Not good. With dust
they (both soft and hard) tend to trap particles against the eye and
over a while dig a ditch from the shifting of the lenses as you blink.

Currently I do a lot of slow remodeling on my 40 year old house and the
dust generated keeps them out. Maybe in a year or two I can go back.

In the past I've been in high (compared to clean air) vapor areas and
had to give them up also.
