Need Help/Opinion Applying lenses to Batman Beyond Cowl

[Hero of Justice]

Hi guys and gals, like the title explains, I need some advice on how to apply lenses to a Batman Beyond cowl. Yes, I've tried just simply hot gluing it, but it will not stick. Also the clear part of the lens that I cut from a water bottle cuts the crap out of my nose . I guess what I'm asking is how do you guys go about attaching lenses to a Batman cowl?

Here are some pictures of what I'm working with;

This is just to show what the inside of the cowl looks like.

The lenses were glued on the inside in this pic, but they did they do not stick for long and easily come off. Not to mention they cut up my nose pretty bad so...

The lens material I used are from Tjack. He's such an awesome guy.

The lenses aren't attached in this pic, I'm just holding them in place.
My fingers' in the way of the camera for some reason lol.
Also, Marck Vick Batman Beyond cowl by xtreme design fx. I can not tell you guys how much I love this cowl.


Any pro tips or advice will be greatly helpful. I could go without the lens and just use colored contacts or whatever, but I've already payed money for them soooo... TOUGH COOKIES

You can fix it not with glue (not so flexible) but with silicone (like the one is used on bathroom)
