The lens of the eye collects the light reflected from the objects, with the help of the eye muscles, to a place called the retina (retina layer) at the back of the eye. In this way, the light is transformed into electromagnetic stimuli thanks to the light-sensitive rod and cone-shaped cells in this section. The act of seeing occurs because the human brain processes these stimuli as images.
If your vision is bad, for example, if you see blurred; this is because there is light in the environment coming from different angles, making it difficult for your eyepiece to focus. This is what creates light pollution. So is squinting really the solution to prevent bad vision?
Yeah! In such a case, when you squint your eyes, you can block the unnecessary light in the environment with your eyelids.
In cases where the image is blurred, squinting has the effect of looking at the world through a smaller hole. This allows you to see more clearly. Of course, there is another interesting aspect of the eyepiece, which is that it has a structure that can flex and change shape in order to see objects better, regardless of whether they are far or close. However, the stretch limit of the lens decreases after a certain age.
Thus, we can say that old age is a stage in which the ability to see is weakened. Some people may also experience vision problems because their eyes are protruding forward. That’s why sometimes the elderly or people who can’t see well due to the physiological structure of their eyes can also apply this eye squinting method. However, you should know that this method does not provide long-term effects.
It is possible to see clearly without squinting. How Does?
an eye surgery called Lasik; It is done by changing the shape of the anterior part of the eye so that the light is more accurately focused on the back of the field of view. This process is done by applying the laser method.
You can even see people who say, “I had my eye scratched with a laser,” after having this surgery. Since the result of such medical applications will vary from person to person, it is extremely necessary to consult a doctor, otherwise undesirable results may be encountered.
