The inside part of your shirt around your waist is usually clean enough to just wipe your glasses clean without any cleaner. Rub in small circular motions until you get the entire lense
I made the mistake once of cleaning transitions lenses with a paper towel. Those scratches were not small or unnoticeable sadly. Since that experience, i strictly stick to microfiber.
I didn’t have transitional lenses, but I had the same set of lenses for like 10 years. I just used tissues and tshirt to clean them. I never had a problem with visibility, but around the sides, some coating was coming off, but I never noticed it while wearing these glasses.
I've found that denim does a rather good job. I actually have a couple cleaning cloths cut from old jeans, but I mostly just use the leg of whatever pair I'm wearing.
The longer you wear them, the easier it is. I didn't get glasses until I was over 20. I wasn't used to them, so I would have to clean them about every hour. Now that I've been wearing them for the better part of ten years, I don't even have to clean them every day.
