Did you know that more than half of the entire populations are shortsighted? There is an ever increasing group of people who rely on reading glasses to see clearly. This isn't really a serious short coming by any means. It is natural due to the process of ageing. More often than not people over forty have presbyopia which is the reduced ability to visualize close objects clearly.

• What one must understand is that presbyopia affects the power to see only nearby objects it never affects the ability to see objects at long distance. So you can see that glasses will be needed by these individuals only when they are inspecting close-at-hand objects. For instance doing activities like reading, writing, knitting, or working at the computer. If glasses are not put on while doing any of these tasks there may be headache.

• Now you'd probably want to know about these glasses that you have to put on in case you have presbyopia. Glasses such as the ones used for presbyopia come in both full and half frames. Full frames are generally suggested for people who need to objects close at hand on a regular basis and for a considerable period of time. Then again there are some other considerations that you must look into. For instance if your job requires you to look at long distance objects at the same time as close ones then you might want to go in for half frames rather than full ones because the full frames may cause a problem in focusing on distant objects.

• People who have to look at both distant and close objects simultaneously will have the greatest benefit by going in for the half frames. The lenses in these frames are placed really low so that when you need to look at distant objects all you need is to look above and over the nose level.

• There is one problem in this scenario. You may not want to put on your glasses every time you dine out or have to check any list like the movies. It can be awkward socially.

• If you want to save yourself from such embarrassing situations where every time you have to scrutiny something you dive into your handbag to fish out your glasses you better invest in foldable reading glasses. These are slender and have cases resembling pen holders. They can be carried in pockets. The cases are hard to crack so the glasses do not have any undue pressure that may break them. These are finished in a way that makes them appealing even with your best evening dress.

• The best thing is yet to come. Did you know that you can wear these cases in the shape of pendants? That's not all. Some cases are the size of credit cards so that they can be flipped out at your convenience. The lenses themselves are very strong due to the acrylic frames that they have so you don't need to be on your toe while using them.

• They are very small and sleek and fit into the tiniest of spaces whether in your pocket, clutch or wallet. So you don't need to be wary of using them in public.

The best thing is that both the cases as well the lenses come in a variety of colors and shapes. You don't have to restrict yourself to boring old and outdated ones if you don't want to. Moreover these are made of the best grade material of glass and plastic so that they are long lasting and durable.
