There is still no definitive known causes of shortsightedness, longsightedness, astigmatism, strabismus (lazy eye). Possible causes of vision problems are extensive near-work strain such as reading or computer work, the environment, and the parents’ genes. Professional eye specialists recommend early screening for vision problems. Glasses or contact lenses are prescribed to help patients see clearly, and prevent further strain or eyesight deterioration.
Dr Bates View
Dr William Bates concluded after decades of researching for an alternative to prescriptive glasses, concluded that mental stress is the root cause of vision problems such as myopia, presbyopia, hyperopia, and astigmatism. These problems are not hereditary, as commonly believed. One simply need to note that virtually most of the baby or toddler is born with perfect vision regardless of how badly the parents suffer from myopia or other vision problems.
The extensive research conducted by Professor Young and his team conclusively proved that 98% of the Eskimo children do not need glasses until they are introduced to schools (60% suffered from myopia post-school). Therefore, vision problems are usually not inherited but resulted from poor vision habits and mental strain.
The good news is that these vision problems are temporary, and the eyes are capable of the natural way of healing, as experienced by thousands of ordinary people, including eye doctors (such as Dr Roberto Kaplan, and Dr Jacob Liberman who have written books about their vision therapy practice).
