How do glasses work in myopia and hypermetropia? 

Have you ever wondered, friends, how do glasses work physics? how do glasses work diagram? how do glasses work for myopia? how do glasses work for farsightedness? how do glasses work for nearsighted? Many such questions are lingering in our minds. But today in my blog I am going to explain to you why glasses.

First of all, I would like to tell you that this is the function of spectacles, it works on the principle of physical optics.

Now that’s how you say it?

There are two types of lenses in your glasses one is either plus lens (convex lens) or minus lens (concave lens). Plus lenses have convergence power and minus lenses have divergence power.

Before we go any further, let us first understand exactly how the number of spectacles come to our eye. And let’s see what kind of eye defects there are:

No refractive error

When light rays go into your eyes and they fall exactly on your retina and create image in the eyes and so you see clearly. In order for you to see clearly, all the rays of light must fall properly on the retina

Myopia (Nearsightedness)

When the rays of light enter our eyes, they do not fall on the retina fall before retina, Therefore, the image does not form on the retina. because of that you can’t see or look dim.

Hypermetropia (farsightedness)

When the rays of light go into your eye, they fall on the back of the retina without falling on retina. in this case, too, you see less or do not see, Because light rays do not fall on the body, the image is not formed.

Let us now, see how the glasses work?

 How do glasses work? help you see, in myopia, hypermetropia, refractive error. 

Looking at the photo above, you will know exactly how glasses work. In myopia defects, the conversion power is Slight before the retina, So the light rays do not fall on your retina, and the same convergence power is carried forward a little by using minus lenses.

Your spectacle number depends on how much power it takes to focus the Convergence Point on retina.

The same amount of lenses work in hypermetropia. In hypermetropia, light rays fall on the back of your retina, And so the convergence point is also behind retina.

As you can see in the above image, Plus lens has conversion power. The convergence point is behind the retina, so It is fixed on the retina with the help of Plus Lens (convex lens). and your vision get clear. the amount of power you need to focus convergence point on retina is the number of your glasses.

This way your eye gets numbered and you can see the clearly with glasses. I think your doubts have been dispelled and you have found the answer to your question.
