That fails completely because they almost always don't have softgel oil-dissolve forms or the right dose at all. They're generally very far from it. It is exactly what leads to the autoimmune issue of dry eyes in the first place.

I tried tons of forms. My current ones are gel-filled capsules. Rather large ones, at that.
Sorry, but there's a huge amount of scholarly literature on this question. I've read tons of it over the years, and there is NO magical supplement that does anything but mildly improve the situation.
Forms alone won't accomplish anything if the dose isn't correct. With regard to vitamin A, some people confuse it with beta carotene, with the latter not working so well for this effect. Vitamin A even has evidence backing it as per PMC6462169. It does take a few weeks to begin to work. Even mild improvements stack up. It may not eliminate the need for an additional intervention, but it can mean the difference between whether the additional intervention will work or fail.
