Abstract

I solved the riddle of cataracts. Wedge-shaped cataracts are caused by accommodation of the eye in ages of presbyopia. The pressure from the lens capsule which made by accommodation causes the shortage of oxygen in epithelial cells of human lenses. This shortage of oxygen crushes epithelial cells. Wedge-shaped cataracts begin. The accommodation also distorts healthy human lenses in the advanced ages. This distortion impairs human eyesight. Many people lose their eyesight by cataracts and lens distortion. But we can prevent both. Reading glasses of sufficiently strong power avoid the harmful accommodation. If people use reading glasses properly, at most 90% of cataract surgeries decrease. Most cataract surgeries become to be needless. We can decrease cataract surgeries all over the world. 


Introduction

Cataracts are the great cold case.
 I write this paper in such easy words as general people having little knowledge of science can also understand. This is because cataracts are concerned with many fields of sciences, society, and people's daily lives.
I took care not to use any word which is not in ordinary dictionaries containing about 80,000 words.
 An eye doctor in the
countryside attempted to clear up riddles of wedge-shaped cataracts. He had two clues. One was his own experience as an eye practitioner. The other was a document written by David G. Cogan.
I searched literature and thought about wedge-shaped cataracts. And then, I resolved the riddle of cataracts. As a result, people can prevent cataracts and related lens diseases. And moreover, this paper can reduce financial burdens in many countries, because this paper can decrease cataract surgeries all over the world.
Although I think it is very difficult to read this story of the complicated eye for people, please do not give up halfway.
