Bad eyesight and not wearing glasses

Bad eyesight and not wearing glasses?

Humans have been very ingenious in inventing objects that make up for defects in the human body. Through the ages humans have faced difficulties, some of which they might not have understood at the time. These included a lot of diseases and other conditions of the human body such as defects of the ear, eyes etc. These were quite common situations and a lot of people had difficulty with hearing and seeing.

But humans are not the most intelligent beings on the planet for nothing - as early as the 12th century we realised that glass can be used to magnify things.
From this discovery, to the 17th century, the design of glasses took many shapes and forms - from polished glass spheres to flat pieces on frames that were held to the eye. In the centuries to follow, glasses were too expensive to be used by the common man. This made it the exclusive to the rich and noble. However, even the upper levels of society did not use it to read or improve vision as much as they used it as a fashion accessory. Slowly with time and improved technology coupled with increased awareness, people started accepting glasses as a simple and effective way to correct defective vision.

Most people who need glasses have defects in their cornea such that the refracted image is not directly onto the retina - it's either in the front or in the back (hyperopia and myopia). Another condition is astigmatism in which the shape of the cornea is not smooth causing blurred image.

These eye conditions are present from birth and their severity may differ in different individuals. It is believed that having bad eyesight and not wearing glasses worsens your eyes. However this is not entirely true. Bad eyesight and not wearing glasses is not directly proportionate. If you have a predisposition then your eyes will get weak whether you wear glasses or not. The only thing that wearing glasses will change is the time taken for your eyes to progressively weaken.

In cases where the defect in the eye is severe, and the person is older in age, sometimes bad eyesight and not wearing glasses do not have to go together. In such situations the person can wear contact lenses and even get laser eye surgery to improve the condition. These alternatives to bad eyesight and not wearing glasses are proving to be very successful as more and more people are opting for it. These allow for improved eyesight while avoiding some of the drawbacks of glasses.
