Gas Permeable Newbie Question?

Ricardo · #1 (**permalink**) 08-31-2009, 08:52 AM

Hope you don't mind a basic question here - Is there an environment or humidity or weather condition that makes lenses like the Boston 7s or other gas permeable lenses ideal, or is it just a personal Preference that make people choose them over ordinary lenses in general?

I've been hearing about them but I don't think any of my friends use them.

Thanks...

We love basic questions here on Lens 101. I haven't actually seen very many really advanced questions here, come to think of it.

Anyway, in answer to your question, someone here on Lens 101 asked if it was safe to wear Boston ES contacts in a sauna, and the answer is yes. The lenses do not fog up because they're at body temperature. Here's the link: http://www.lens101.com/boston-es/7823-boston-es-contacts-safe-sauna.html

As far as weather conditions such as temperature, I would imagine that the contact lenses like the same weather conditions as you do: moderate. Not too hot, not too cold, medium humidity, that sort of thing.

I don't wear Boston 7 lenses myself, so I can't tell you why people choose them. Most of them probably choose Boston 7 because that's what their doctors prescribe.
