My visual span for reading is 3-4 characters. It doesn't matter how long I stare, this despite passing normal vision tests with prescription glasses (Snellen & peripheral lights). Despite tests while growing up, they didn't give me glasses until many years later than I should have. It's like my acuity falls quicker when moving degrees from center than other people. Brain during this critical development period didn't fully align, calibrate & allocate resources to the wider span & peripheral. I think my brain focused more resource on the 0.5 degree (still blurred but visual processing makes some sense of it) so less was allocated to the remaining macular & peripheral vision which held less detail (like extreme denoise processing just blurs the image further). Cognitive exercises failed to improve outcomes & are often designed for later stages in the visual process where optical & low level processing is assumed to be fine. It's like assuming miracles can be done to turn 32 bytes into a 3MP detailed photo. GIGO. Exercises to increase working memory & number of objects/features in an image/frame assumes that many objects can be seen without moving eyes. I also get dry eyes from a lack of oil layer. Adding oil, being fatigued/tired then blurs my vision. YMMV.
Thank you 🙏
You’re welcome 😊
