Near-Sightedness - What Does it Mean?
There are many short sighted people in the world. It is probably the most frequently encountered reason for needing to wear spectacles - at least in more modern countries where blindness due to nutritional deficiencies or infections are uncommon.
You find that with people who have short sightedness, their eye sockets are too long. Because of that, when the light beams come into their eyes from an object in the distance, the person’s cornea and lens are too powerful to focus the image on the fovea of the retina. Short-sightedness manifests itself when individuals can clearly see close-up objects however distant objects will appear blurred and fuzzy.Subsequently, the picture of the tree or television or whatever is not clear.
So, people with near sightedness see things that are nearby without any difficulty. But if they are trying to look at something in the distance, they end up squinting to see the image more clearly.
You commonly find that younger people suffer from this condition more than older people, at least that’s when the problem starts. Hence, you find kids getting teased about wearing spectacles at school.Actually the problem can even get better as an adult, as the muscles controlling the lens get weaker or stiffer
Spectacles or contact lenses will push back the image’s focal point and place them correclty on the retina to bring in a clearly viewed image.
