Hello Everyone, I am new to wearing contacts (3months) and was changed to daily disposable lenses because I overproduce oils or protein deposits or whatever but it causes the lens to age much quicker and the optician thought daily disposables were a better option, and they have been. I stgarted with Acuvue moist one day lenses and changed to a different one that offered me more comfort but I did and occasionally do insert them with an insertion device with no problems. I have even kept one in a storage container in solution because I thought I lost it and already opened another but then found it. So I kept it in the multipurpose solution overnight and used it the next day and it was fine. The one day disposables most definitely are thinner but I had no problems and I think in terms of thinner means oxygen can more easily pass through and that is a good thing so I think you can insert them with an insertion device. I have never tried the tweezers end of these devices though only the flat end where you place the lens on and have to say I do feel too squeamish to put the tweezer end near my eyes! Now that I looked at the picture of that tool it looks just like the tool I used only mine looks somewhat shorter but the end or part you use to put the lens on looks the same and it worked well with the daily disposable lenses for me.
