There are plenty of modern contact lenses that can be worn for longer periods than just a single day without issues. As far as I understand it, this comes from enhanced materials, letting through more oxygen while retaining more moisture.
I use Air Optix (http://www.airoptix.com/safety-information.shtml http://www.airoptix.com/safety-information.shtml), they say up to 6 nights is fine for their baseline version, with up to 30 nights for the Night & Day product. Not affiliated in any way, just a customer.
- stephengillie 13y agoI got a blister on my eye from Night & Day contacts. Then in got LASIK. That was in 2005, best choice of my life.
- codex 13y agoSadly, this is true for some, but not for others. I find even Air Optix uncomfortable. It's not the freshness of the contacts themselves, it's that my eye reacts to wearing them after awhile--even brand new pairs. If I go a few months without wearing them, I can tolerate them for a week or so.
