Fish eye lens effect

Putting It All Together

Step 1:
Pop the lens out of the glasses. Apologize to grandma if she sees you doing this with her favorite pair of glasses.
Step 2:
Tear off two pieces of electrical or masking tape long enough to fit around your glasses’ lens, then stick ‘em onto the top and bottom edge of it.
Step 3:
With the tape ready for action, carefully put your newfangled fisheye lens over your camera’s lens, the same way the eyeglass lens normally would be in its frame.
Step 4:
With the tape, secure everything down so that the eyeglass lens ain’t budgin’ from your camera’s lens.
There ya are!
