CREATING DOUBLE EYELID CREASE
I personally find eyelid tapes to be unnatural and frustrating to work with, especially when I like to put eyeshadow. Normally it is easier for naked eyes for eyelid tape but I do not recommend it as there are better ways to make eye crease. Currently there are 3 tools that i know of used to create an eye crease: Eyelid tape, Eyelid glue and Eyelid fibre.
Eyelid tapes are simple and straightforward but can be difficult to work with especially since not every eye is the same. They may need different curve, length and strength etc. Also, others might see that awkward piece of plastic when you look down and may awkwardly ask whats that plastic stuck to your eyes so I dont really recommend it haha. Although you may cut your own eyelid tapes, I personally just can’t be bothered lol.
As for eyelid glue, it may take a few practices but i find it useful to create shapes or extend your natural eye crease if needed. Eyelid glue does not work well with eyeshadows as they may get clumped up and create this weird pattern on your eye lids :( but with a naked eyelid i find it works great and realistic. When you look downwards others may see a mini crease like you had your eyelids stitched up but it’s barely noticeable so dont worry (depends on the area you apply though). 
I highly recommend eyelid fibres! It is very popular in japan right now and it is like the holy grail for eye crease basically haha. An entirely new upgrade from eyelid tapes, eyelid fibre is basically a thin clear string with a sticky surface. Tighten the string by pulling on both ends, place it on to your closed eyelid and gently press the position where you want the eye crease to be, gently push downwards and open your eyes at the same time and the eyelid fibre will be stuck at the very inside of your new eye crease! VERY natural and the best thing is you can wear this with makeup and nothing comes off! I am in love with this product even though since i already have double eyelid crease but i use it to create higher eye crease when i do more dramatic make up. I highly recommend eyelid fibre!


EYELID SURGERY
As for eyelid surgery, I do not know anything about it as it has never crossed my mind. The methods i mentioned above seems to be satisfiable in my opinion for anyone who wants double eye crease but I respect whatever choice you make. I searched around for informational links and maybe you should check them out if you’re still interested. :)
