According to Joshua Silver, a physicist in the UK, one of the biggest problems in developing county is shortage of optometrists. For example, in sub-Saharan Africa, an eye care professional has to take care of more than eight million people. It means that shortsighted
people can hardly get glasses or contact lenses there. To ameliorate this situation, he invented glasses of which we can correct the degree by ourselves. With the glasses, we don't need for optometrists anymore.
Even though I live in a developed country, I want to have such kind of glasses, because it would make my life easier. First of all, if I have them, I don't need to go to meet eye doctors so often. Our sight tends to be swayed with our age, so actually I have to go there often. Next, that means I can reduce my medical expense. I don't have to buy new glasses according to the transition of my sight. I really wish they will be mass-produced in the near future.
