Mixed up contact lenses...

Lagz · 25 Aug 2010 at 10:33

I took my (new) monthly lenses out and put them into a cleaning case, but unfortunately my old pair were still in there. I didn't realise this until I tried to put them back in, so I now have two left contacts and two right contacts, and I don't know which are old and which are new.

Is there any way for me to figure it out?

nope! i did this also, ha!

you could try each lense and see which feels new ?

Ha I did the same thing few months back.
Only way I could tell is if you look really close there should be some imperfections / scratches etc on the old ones, perhaps even a little more worn around the edged. They may also have a more lax position to them since they have moulded to your eyes shape, where the new ones may feel quite stiff.

in before; 'To the internet' !

Argh. That's the best solution I could think of as well. I don't really want to risk accidentally wearing the old ones for an extra month though, since I have had problems with my eyes in the past (and so don't want to take any chances!).

I think I'm due a new delivery of lenses next week, so I might just guess until then and then bin both sets and start again. Annoying!

Monthly lenses will last longer than 4 weeks, I remember I had my first pair for 5 or 6 weeks (try before you buy) so they should be safe to carry on wearing.
