My time has come!
The above stereographic image is for cross-eyed viewing (most stereograms are wall-eyed, so you may need to put your finger in front of your screen until this one comes into focus)
This is an image of Honolulu, Hawaii, published by NASA. Note Diamond Head (the volcanic crater) in the south.
Here are some other stereopairs published by JPL:
Wheeler Ridge, California
Mount Saint Helens
Salt Lake Valley, Utah
Wellington, New Zealand
LOL. Cross-eyed viewing is extremely easy and is very easy to do on both a laptop or desktop display as well as a phone. It takes no strain nor do I need any “devices.”
These images are easy to see and take no effort. It seems like the issue is with you.
