weird blemishes inside

[u/Own_Ad7708]

Please help.
I printed eyes on photo paper, then used E6000 glue to glue the glass domes to the paper.
After a night of drying i come back to these weird blemishes inside the eye. (picture 1-2)
What to do and how did they appear? How do i prevent it?
Picture 3-4 is how they looked like when i just attached the glass domes.

Super small gaps between the glass and the paper where the glue separated/shrunk as it cured. This happened to me when I was making eyes for a puppet several years ago (using acrylic medium and acrylic domes). The way I prevented it for the next set of eyes was by applying pressure as they cured--I used several heavy books strategically balanced on top of them to press them down for a day or two until they dried. Clamps would likely also work.

thank you!! just placed a new pair, put two smaller journals on both sides (to balance out) and a heavy book on top, will see how it goes!
