The reason why I chose this inventor is pretty simple: he was one of the scientists who helped people with bad vision to see this world in all its beauty. 

 1. The achievement of August Müller was grinding scleral lenses from blown glass and using them in his medical practice. 

2. Refinements in his process led him to be able to correct his own severe -14 dioptre miopia to within 0.50 D. 

 3. Müller's compatriot Adolf Fick had published his work on contact lenses earlier in 1887, but his lenses were heavy and could only be worn for short periods.

 4. Müller's lenses were lighter and shaped to match the curved contour of the cornea. 

 5. Müller called his development Hornhautlinsen or 'corneal lenses'. 

 6. His efforts to develop a new corrective lens were ultimately unsuccessful, since a patient could only tolerate the lens bearing down heavily on the sclera for half an hour, less than those of Fick. 

 7. Moreover, it had to be inserted underwater to prevent trapping air bubbles, and cocaine administered to anaesthetise the eye. 

 8. He did however lay the groundwork for later researchers and his ideas and recommendations on fit, tear flow and rounded edges still form the basis for contact lens fitting today. 

 9. In 1932, Müller donated three lenses to the German Museum in Munich. 

 10. Otto Wichterle was a Czech chemist who developed sylon and started making contact lenses from this material. 

1. Despite his emigration, Kit stayed a conscious Belarusian through all his life: “Everything I did in my life —- I did for my homeland and its fame”. He lived out his final years in a Jewish nursing home and celebrated his 107th birthday in 2017. He died on February 1, 2018.

2. Since Borys's youth he had strongly loved history. When he had been applying to Vilnius University, he wanted to enter the Faculty of History. But as soon as he noticed hundreds of people standing in front of the HistFac's doors, he chose to apply to the Faculty of Mathematics, where only five people're standing. 

3. In 1944 Barys Kit was arrested by the Gestapo. He was imprisoned in Vileyka. And his former students have saved him from execution.

4. As a school inspector of the Baranavichy District, he contributed to the foundation of hundreds of Belarusian primary and dozens of secondary schools.

5.   Barys Kit spoke 7 languages including: Belarusian, Russian, Polish, Ukrainian, French, German and English. 

 6. Kit is the author of the first manual on rocket propellant "Rocket Propellant Handbook", published in 1960.The book received many positive reviews and is referenced in rocket science publications even today. Thanks to him, it became possible to travel to the Moon, run the program "Shuttle" and more other. 

7. Barys Kit used to meet V. Bykov every day for the whole year. Bykov was writing down his stories. According to the scientist, this was the most exciting year in his life!
8. Recipe of longevity:

9.  A "time capsule" with Kit's name was immured in the wall of Capitol in Washington, D.C.(according to other data, this capsule is now in a special repository of Harvard University and will be opened by descendants only after 500 years).
