What to Know if You Can’t See Distinctly
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. Essentially, the difficulty with this condition is that the eyeball is just too lengthy to allow the light from a distant object to become focussed into view, quickly enough by the eye’s cornea and lens system. Therefore there is a blurry feel to the image that’s relayed onto the back of the retina. The eyeball is just too long compared with the focusing power of the cornea and lens. This means light rays from objects in the distance are focused in front of the retina because they’ve been bent too much by the cornea and lens. They find getting a clear image of distant objects is difficult, but seeing things close up is fine. Children may perform poorly in class because they’re unable to read what’s on the whiteboard.Headache is a common symptom. The child is unable to do his lessons with any pleasure because of the strain on his eyes.
Often, the condition is first noticed in older children and young teenagers. Short-sightedness can run in families, so short-sighted parents are more alert to the possibility of their children having sight difficulties. 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.
