Distant vision and near vision

As we all know, eyes are very important to us. We need them to read, to watch and even to express our emotions. As a matter of fact, most of the people could hardly image lives without them. However sometimes we still didn’t care for them properly so that our eyesight becomes poor and poor. And perhaps you also found that, our parents also have vision problem with their eyes due to aging problem. Thus, we have to use eyeglasses to correct our vision. Otherwise, everything around us will be blurry and that makes everyday living inconvenient.

The vision problem majority turns out in two situations. In one case, the distance vision is affected which is called myopia and the other will have trouble focus on close objects such as reading, and this is called presbyopia.

Near Vision Problem (myopia)
The near vision problem normally takes place among younger generation, they over used their eyes focusing on close objects such as reading and TV watching. Thus weakened the flexibility of the lens to focus on distance objects. Concave lenses will be used to correct this vision problem, indicated with negative sphere power (-2.50 SPH for instance) from the prescription. Earlier treatment plus appropriate eye sight exercise could reduce or even cure myopia. Otherwise you will need to wait till mid age wish presbyopia take place to cancel out myopia a bit.

Distant vision Problem (presbyopia)
With age, the lens hardens and becomes less and less able to accommodate. People will be able to see objects at far distance but everything close up becomes blurry. That’s why you can see some people used to put things a little bit far away to get better focus. Convex lenses will be used for this kind of vision problem, indicated by positive sphere power (+2.00 SPH for instance) from the prescription. The eyeglasses prescription may increase along with aging.

With the understanding of above sight problems, you should be able to find out the correct eyeglasses based on your prescription. Always go to a reliable optical store to make sure they give you the correct eyeglasses which will help improve your vision problem.
