I have a triple folded eyelid on my right side, which creates asymmetry with a double eyelid on my left side. I was initially skeptical that Optifold would work, but have been very impressed by the quick results. While I have only been using the product for about 2 weeks, it has thus far worked even better than advertised.
After my first night of wearing it, my triple fold became a double eyelid almost identical to my left eyelid. The new fold lasted the entire day. Since then, I've found that I can sustain a double eyelid on my right eye for the entire day even if I only wear the N-tape during the night, which I find very easy and quick to apply.
I'll continue to post updates here. I'm hopeful that over time I will only have to wear the tapes once a month or at an even fewer frequency.
