How To View The Specs Emergency None

State of emergency in sight when no glass eyes may occur during a sudden glasses broke and can not be used, and when the glasses suddenly lost or forgotten to bring, particularly for people who are already old age. While we need all to see. Whether it's for sight distance or near vision.

For example when we are disebuah stores want to see the price listed on the items we will buy. Which one small letter, we do not bring glass eye. Age has more than forty years, whereas if you do not wear reading glasses are not able to see small objects.

In this emergency there was a way to overcome it, is by using the "Pinhole Effect". Pinhole effect principle is in the eye refraction disorder (kalainan decline in eyesight can be corrected with glasses), the vision will get better if through a crack or small hole.

At the time of an emergency, we can make tools made from a small carton, size 3 x 5 cm, then in a thin cardboard or paper made a hole, make a hole by using the tip of a pen. So we can peek through the crack hole. Of course, small letters will appear.

But there is a more practical, so we do not have to make the tools we have to make first. That is using our right hand. We will see the object grasp with his left hand. Then we use the right hand instead of a tool that has been described above.

By making a small gap between your thumb and forefinger. From these gaps will be seen objects more clearly and be legible. This applies to far or near vision. So even though we are in a state of emergency does not use glass eyes can still be saved in this way.
