They say that the eyes are the windows to the soul, but the windows that frame our eyes are glasses. Glasses and other eyewear including contact lenses are used by all sorts of people. Some 40% of people in the United States need a form of vision correction. Glasses are an important invention and help many people around the world to be able to do what they want and need to do. But how do glasses work? Continue reading to learn the answer to that question and to learn more about how glasses impact our society.
Eyes Are Very Complex
The mystery of how glasses work is complicated by the mystery of how eyes work. The puzzle of how eyes work is less of a mystery today, but can still be difficult to understand from the outside looking in. The little black dot that is located in the middle of your eye that constricts and contracts as you look around is called the pupil. The pupil allows light to enter your eye and the light bounces off the back of the eye which is covered in an intricate web of nerves called the retina. A person with good vision will have pupils that allow light to focus squarely on the retina.
Inside The Eye
Within the eye, there are several systems that help a person see different things that they are looking at. These systems bring the light into the eye onto the retina and then minimizes the light and shapes it to the retina, creating an image. When light is unable to pass through the retina properly or cannot center on the retina, a person will have a vision problem. Glasses were created to help alleviate this issue.
How Do Glasses Work?
Now that it is clear how the eye works, how exactly do glasses work and help with vision issues. Well, because eyesight issues are the result of light not being able to reach the retina within the eye, glasses and other prescription eyewear are used to help the light travel better to the retina. Glasses do this by bending the light as it moves through the lenses of the glasses, allowing the light to enter through the pupil at just the right angle to reach the retina.
The Results Of Wearing Glasses
The result of a person wearing the right pair of glasses with the correct prescription is that that person will now have the ability to see clearly in the same way that a person with 20/20 vision can see. There are several different prescriptions that have been created for people with different kinds of eye conditions. Some of the most common forms of eye conditions include nearsightedness (also called myopia), farsightedness (also called hyperopia), and astigmatism.
