To give you some idea on how reading a book at is quite impossible without glasses. At a normal reading distance, I can’t make out anything other than colors and smearing black lines.
Notice how my -11 glasses makes everything smaller. The mineral water bottle now come into my field of vision. However, things become sharp and easy to read. The word ‘mingle’ which was almost invisible before has suddenly pop out. Colors become people and faces
The glare on the lower left is annoying. Compared to the blur however, it become a minor annoyance.
