You can today buy reading glasses from nearly every high street chemist and other such outlets. Unfortunately many people do not bother with them because they do not understand what to do.
Going to an optician and getting a prescription for some people can be a long winded affair. This is where non prescription lenses can help. They are ready to wear and do not require a trip to the optician. Although it is recommended that regulal eye checks should be performed by an optician.

They are designed for people who can see clearly at a distance, but notice that they are beginning to have problems reading up close unless they squint or move the reading matter further away from there eyes. In most cases problems start at about 40. For the next 10-15 years it continues to get worse with age. Because of this the reading glasses have to be made a little stronger every couple of years to compensate for this loss of accommodation which is the ability to change focus.

The loss of focusing ability is normal and natural and happens to everyone, you are not going blind, as some fear. What is happening is that the focusing behind the eye is becoming less flexible as it ages, and the muscles that are working on this lens are also getting weaker with age.

Non prescription glasses are reading glasses and can only be used for reading close up and will blur the distance. You should therefore take them off when you have finished reading. Because of this limitation some prefer to use what are called half eyes. These are glasses that are only half as large vertically and ride lower on the nose so that you can look over them to see in the distance. You have the option to leave them on or take them off after reading.

However I hear you say which would be the right pair of glasses for me? You can buy glasses with different vision dioptre strengths and different styles. The style is up to your own personal tastes, however the lenses can only be as sufficient as to what you can or can't see. Both lenses are the same strength and have a setting on the lens etc of 1.00 or 3.25 for example. Some can go as low as 0.50 going up in various strengths to 4.00 it is recommended that if you go beyond this then you must consult an optician.

Okay now onto which lens is the correct one for you. Unfortunately to put a proper reading chart on here is quite an achievement so here begrudgingly is the best that I can do for you. I hope that you will get the idea that I have tried to convey as everything I have tried comes out blared. To find the strength you need check out the following chart for example WITHOUT GLASSES from a distance of approximately 14 inches or 35cms.You should go for the one that is clearest and with the optimum strength that you require. However please remember that these are non-prescription glasses we are looking at, and the chart below is for guidance only.
Can I suggest that you go online and look for a better chart perhaps on Google etc just type in the following phrase and several should be on the first page on Google - non prescription glasses chart.
I hope that this article has helped you in some way and if it has please vote for it accordingly.
