In Taiwan, 87% of senior high school students have nearsightedness problem. In all Chinese nations, nearsightedness cost around 269 billion dollars lost collectively. In real life, nearsightedness could also deteriorate to entirely blind. From a monkey Experiment, it's proven that heredity is just one of the factors that cause myopia. Actually, environment matters more.
In the era with more and more prevalent small personal devices, nearsightedness is very likely to become a worldwide issue. Therefore, in this project, the goal is to find a better solution for this imminent challenge.
THREE KNOWLEDGE ABOUT MYOPIA
There are three important information we have to know about myopia. 1. Heredity is just a small part of factors that would get us nearsightedness. 2.The biggest factor which causes us myopia is because we look at something too closely for too long. 3. The eariler we have this problem, the worse level of myopia we will be.
When we look at a close point, our crystalline lens will contract and become thick. If we are still at our growth period, younger than around age 20, this kind of contracting crystalline lens will gradually deform our eye ball and elongate it. According to this starting point, doctors and scientists bring up a treatment or precaution named Fogging Method.
Fogging Method is an application of a very simple thought. If highly contracting crystalline lens would cause myopia, why wouldn't we use a artificial lens, eye glasses, to release it?
USING FOGGING METHOD NEEDS TO SWITCH GLASSES
However, even though this method was brought out almost a hundred years ago and believed the best solution for myopia , it's not popular and known at all. The reality is, fogging method is a bit not logical in our behavior. For most of the people, the main reason to avoid having myopia is because they want to avoid putting a eye glasses on them. Putting an eye glasses on to avoid putting an eye glasses is just simply not attracting eventhough it's believed the best way of preventing myopia from happening.
Moreover, ironically, getting myopia is actually helping us from deterioration at beginning if we do not take any action because elongated eye ball actually helping relaxing crystalline lens. But unfortunately because we need to see the words on the blackboard clearly, we put on the eye glasses for seeing far which again contracts our crystalline lens.
In summary, if you want to use fogging method to prevent myopia, you need a glasses for reading or any distance short than 40cm. if you want to use fogging method to prevent the myopia from getting deteriorating, you need to switch glasses for different purpose.
Since the biggest obstacle is people need to switch glasses between scenarios, why wouldn't we create a glasses which could change its diopter automatically? make it a smart lens? Hence here is the final output of the project.
EXPERIMENT AND MAKING
In my picture, the final result of this project is a simple transparent lens which looks just like any glass lens nowadays and can fit into all the glasses frame, so I didn't give it a design for product and that's a big fail in IDE course. However, therefore, it's a really good and deep lesson for me.
