What is confusing to us all has a specific meaning. A plus sign in front of a number indicates problems with distance vision, The minus symbol denotes a problem with seeing up close. These numbers are the sphere and the higher numbers indicate a more severe problem with your vision.
Next you would have the cylinder. Cylinder numbers are usually negative and are indicative of astigmatism. This eye condition makes distance vision very blurry. Only things very close to you can be seen clearly.
The axis also plays a role in correcting your vision. It is in relation to how a prescription is placed within a frame. Most often, it is set at 90 or 180 degrees, but if not set correctly you will have problems with the glasses that will need to be corrected.
Having your prescription made up into a pair of corrective lenses is performed by the optician. An optician is a person who is highly skilled at interpreting the doctors prescription and fitting you properly. Just prior to this, you will have to pick out a frame that you like and with all the choices you have, this is no easy task. Measurements will taken while you have the frame on. If, by chance, your frame is not adaptable to your prescription, you will be informed and another frame will have to be chosen.
In years past, no one was thrilled about wearing glasses. Most were round with a wire frame and children could be picked on mercilessly for wearing them. That has all changed with glasses coming into the world of high fashion. Shapes and frame construction are made up in numerous styles to suit the pickiest client. From round to square and everything in between, glasses have come into their own.
When it comes to the lens, you even have options there. They can be constructed of plastic or glass. They can be tinted in four different shades. The glass can be transitioned into sunglasses on days where the sun is bright. New grinding techniques make for glasses that are much more flattering to wear. If weight is a problem, there is plastic with titanium frames.
Eyeglasses can take much more punishment than their early predecessors. They can be twisted and bent and pop back into their normal shape. They can be rimless, plastic, wire, and even wood. They can be a statement of simplicity or understated elegance. Some women are known to have many pairs of glasses to suit different occasions. Even with all these choices there are those who will choose to wear contact lenses. The sky is the limit in eye wear today.
