Peripheral Vision: Unveiling Optical Illusions in News Apps | April 29 2026, 17:56

I’m trying to figure out if it’s just me or do other people experience this too πŸ™‚ if you look anywhere except at the word “Omurbekova”, the line highlighted in red in the second screenshot (which is actually white) is distinctly visible in your peripheral vision.

Wild Costa Rican Peccaries: My Unexpected Encounter | December 29 2025, 04:21

Seeing Shapes and Shadows: How Portrait Drawing Changes Our View of Faces | September 12 2025, 15:44

It’s interesting that even a little experience in drawing portraits makes one see patterns in other people’s faces that you wouldn’t think about otherwise. For example, you look at someone’s face, and some points on the face converge into an equilateral triangle. Or the shadow from the sun forms a notable pattern. Or some lines are strictly parallel or perpendicular. And at that moment, you feel like grabbing a pencil and trying to sketch it. At this point, it seems that achieving a likeness is a piece of cake.

Or you notice that a silvery dress is the darkest thing in the picture and probably needs to be depicted almost in black. With highlights, of course. This contradicts the notion that “a silvery dress is just a shiny white.”

Sometimes you look at someone’s face, reassured that the typical proportions are maintained, or, conversely, that they are not. There are also optical illusions. They are the most interesting. It’s when it seems that some point exactly divides a segment in half, but as soon as you measure, it turns out not to be the case.

It’s also interesting that our eyes deceive us about what lines are and what are not lines. Here, it would be more correct not to use the word line” but edge.”
