Reading glasses are needed by people once they reach a certain age. Those who have been suffering from eye problems which does not allow them to comfortably operate on a daily basis would know that they would have to get their eyesight checked. Glasses can actually make a big distance in your life and can help you carry on with your work on an everyday basis like driving, typing, writing and reading comfortably. Clear vision is necessary but there is not much awareness among people about why this is necessary and how glasses can help.
Reading glasses can help you if you suffer from far sightedness. Far sightedness refers to the condition where you can clearly view the objects that are located far away but not the ones which are nearer to you. There would be a blurriness around the image whenever you try to concentrate on an object that is located closer to you. There is a critical distance at which the object would not be visible to you clearly. In order to know what this actually is, you would need to hold some reading material and then start bringing the material closer to your eyes unless it starts becoming out of focus. This point where the object becomes blurry is the critical distance. This condition is medically known as hyperopia and it occurs whenever the image that should be formed on the retina forms beyond it. Convex lenses would be needed in order to make the object focus on the right spot. This condition is normally seen in people who are old.
Reading glasses are also often used for short sightedness. What this means is that you would be able to view things clearly when they are closer to you but not when they are in the distance. This is the problem which is normally seen in teenagers and children in large numbers because of excessive computers and television which harms their eyesight over time. Short sightedness can be quite dangerous and it becomes quite necessary to wear the right glasses if you have problems viewing things at a distance carefully, especially if you would be driving. Doctors normally prescribe concave lenses to correct the vision and make objects clear.
