I used to use daily lenses, but the cost became unbearable, so I recently switched to the monthly Alcon Water Lenses, which are famous for being moisturizing. When I first put them in, they were definitely comfortable without any dryness, which was great, but after a few days, managing them has become quite a chore. ㅠㅠ

Even though I spray saline solution every evening and scrub them thoroughly, my eyes feel incredibly dry by the afternoon, perhaps because the protein residue isn't being wiped away completely. On top of that, the lens material is so thin and soft that I'm constantly worried I might tear them while rubbing them with my hands.

I looked it up and saw that many people these days use machines that remove protein using ultrasound without touching the lenses. Do they really keep them cleaner than hand washing? I paid a high price for the monthly Alcon Water Lenses; I'm wondering if they clean so thoroughly without residue that I can use them like new lenses for the entire month. Please give me some advice if you've used these machines! Haha.
