The common eyeglasses, which started as an accessory for the rich and famous, have now become the most essential piece of engineering that a person wears on their body. Eyeglasses are the piece of engineering that is required by people that don’t have perfect vision. Today we are going to learn how wearing eyeglasses can improve your vision. To learn how eyeglasses can improve a person’s vision, we first need to learn about why we need eyeglasses in the first place.
Glasses have become such a well-known accessory that we all know where we can get glasses online very easily and at very affordable prices, but many people don’t know that why we do we need to use glasses, these people are mostly the ones that do not need glasses in the first place. This article will teach you about our eye problems and how we can fix them using eyeglasses.
Why We Need Eyeglasses
The human eye works by utilizing seven main parts of the eye. The human eye works like a well-oiled machine, the cornea of the eye is responsible for focusing the eye and letting the light refract with the help of the lens and guide it through the pupil which is just a hole that lets the light hit the retina of the eye. Your eyes need to bend the light rays in such a way that a proper image can be made on the retina of your eye, the image that is made on the retina must be very clear and sharp otherwise the brain will not be able to interpret the image correctly. If any of the parts of the eye do not work correctly, the image that is formed on the retina will not be sharp and the brain will not be able to interpret the image.
The Main Eye Problems
The main problems that people face when they cannot see properly is due to some refractory problem and it can generally be identified as nearsightedness and farsightedness.
Nearsightedness is a problem which occurs when a person is not able to see things that are far away from him. The person will be able to see things that are close to him like his hand and his feet but the person will not be able to see what’s on the other side of the room.
Farsightedness is quite the opposite of nearsightedness, in this scenario the person can see what’s on the other side of the room but will not ab able see what’s in their hands.
These problem occurs when the eye is not working properly and the image that is being made on the retina is either in front, or behind.
How the Problem Can Be Fixed
As mentioned earlier the problem exist because the eye is not able to properly refract the light onto the retina thus creating the problem, this problem can be fixed if the image that is being focused either behind or in front of the retina can be adjusted to project image perfectly onto the retina, so that the images are sharp and the brain can interpret them.
How Glasses Work
Glasses work on the basic principles of refraction. The eyeglasses solve the problem by doing the job of the cornea and the lens, eyeglasses refract the light at just the right angle so that it projects perfectly onto the retina creating a perfect image that the brain can interpret easily, and create an image in our mind that matches the surroundings.
