The lash lift looks fab on you @Irina! I've been getting mine done for about a year now (it's the only beauty treatment I do, other than laser). I have similar lashes to you (naturally long but straight) & always get a lash lift rather than a lash curl/ perm - it looks more natural (to my eye).
I do agree with @Star that it can get addictive - especially once your lashes start drooping again around the 6-8 weeks mark (sooner if you usually wear mascara with it). It's just like people who go for regular haircuts - they start to feel their hairstyle looks 'messy' once the shape grows out.
Tip: If your lashes get to that droopy stage & you aren't able to get them touched up soon, you can start using an oil on your lashes to get them to all to fall evenly. Once or twice a day is enough.
I completely understand your squeamishness about getting anything done near the eyes @Jenni & @Janet! I was originally that way too but got used to it now - I actually fell asleep during my last appointment, lol! Which is weird, considering I still can't wear contact lenses because of the sensation of them on my eyeballs...
