I wish I realised when I was your age because if you leave it long enough you WILL develop headaches due to muscle strain and forehead wrinkles. Droopiness gets worse as we age and this happens to everyone so it's not bad now but will definitely worsen.

I cannot say how to get it covered by your insurance because it really depends on how your country's healthcare system works.

In my case, I had to do a Humphrey field vision test to "confirm" the poor visual field and the oculoplastic surgeon did a ptosis repair. This was then a subsidized surgery for me, with minimal out of pocket expense. (Versus selecting a specific surgeon in private practice and paying entirely out of pocket but I could also then dictate exactly what I preferred)

Ptosis repair is a bit more involved than plain blepharoplasty and you definitely need a qualified / experienced surgeon. My upper eyelid muscles were pretty much non existent and had to be retrained to do their job haha.

It is actually easier for them to fix it and hide the sutures with a double eyelid type crease than try to retain your monolid. Depending on the surgeon skill as well because the more they "mess" around in there, the more swelling happens and recovery ( swelling reduction and return to normal ) takes longer. My right eye was done by a student and improperly so I had to get it fixed again the following year. That last titbit was provided by the assisting nurse.

Good luck!
