Form deprivation myopia

  • Worse than lens-induced myopia - unlike the latter, has no any end point - there is an infinite loop of axial elongation;

  • Occurs when eye(-s) receive a diffused (low-quality/fuzzed) image (like you look through bottle from glass);

  • Things probably creating it: image due to actions people use to see clearer (squint, finger holes, stretching the eyelid), dry eyes, low quality or dirty glasses lenses, uncorrected refractive errors or strabismus - misalignment of eyes/images (edit: numbers are relative, to descript better - any uncorrected amount of myopia or astigmatism leading to “effort to see”/“visual cortex signal error”/“distance strain”), poor lighting and lack of sunlight.
