Types of Reading Glasses
Sometimes people experience problems with their vision that is
limited to reading. This does not necessarily mean that they
need to have a prescription from a trained eye doctor. In some
cases they may simply need what are called reading glasses.
Reading glasses are not prescription glasses and can be
purchased in many drugstores and pharmacies.
It may be hard at times to know whether or not you need reading
glasses. The general rule is that if you reach the point when
you are not being able to read up close without stretching your
arms past the limit, then you may need a simple pair of reading
glasses. The reading glasses will magnify the material so that
you can read it without straining your eyes.
There are some reading glasses however that will require a
prescription. What this means is that you only need the glasses
when you are reading and in some cases watching television.
These glasses usually come in two styles. There are full frames,
where the entire lens is made in the prescription. There are
also half-eyes, these are the smaller lenses that contain the
prescription in the lower half of the lens.
Reading glasses can be either custom-made or purchased
ready-made. The ready made glasses are the ones that you will
find at your local pharmacy or drugstore. The ready-made glasses
started to become popular during the 1990's. Research has shown
that three times as many glasses were purchased during this time
then in the decade before. This was due to the fact that they
were less expensive and didn't require a prescription.
There are some drawbacks to purchasing ready made reading
glasses however. In most cases they are made in a one size fits
all form. Unlike prescription glasses, the reading glasses
cannot be adjusted when you buy them. You simply try them on and
take them as they are. This means that you could end up buying
glasses that are falling off your face when you are reading. If
you do not buy a pair of glasses that suits your needs then you
should end up having headaches and nausea. The glasses could
cause more problems with you vision then you already have. In
some cases people end up buying prescription glasses after all.
