A person who is myopia has trouble seeing targets in the distance, but he or she can see close targets well. Nearsightedness is also called “myopia”.

In some cases, myopia is a heritable condition due to an unusually long eye, as measured from front to back. As there’s a longer distance between the cornea (the clear “window” that crosses the front of the eye) and the retina (the light-sensitive bed at the back of the eye), images tend to focalise ahead of the retina, instead of than on the retina itself.

In other cases, myopia is the final result of a mismatch between the length of the eye and the power of the eye’s lens to focus an image in the correct location. Once Again, this results in a state where images to focus ahead of the retina, resulting in nearsightedness.

So, if you are nearsighted, you have to have on spectacles so that correct your visual flaw. The rationale of the lens arrangement within the spectacles is to modify the focal length of the light rays reflected from the target visual object, so that it focuses precisely on the retina. That way you will make out a sharply focussed object in the distance. So your spectacles have to have a lens that counters any blemish in your own cornea/lens focussing system.

Here are some ways you can choose the correct spectacles frame for your face:
Color of the frames:

Blonde persons should choose delicate shades, clear or metal frames, and leave the horn-rims and dramatic shades for people with a dark complexion. Basically, with regards to frame colour, emphasis might be made on eye color by echoing it in a bigger shade, or alternatively the frames can match the hair color.

Picking Out the shape of the frames according to the shape of the face

Oval face:

The oval face shape is the ideal face with perfectly balanced proportions. Any shape of frame looks good on it. However you can seek for spectacle frames that are as broad as (or wider than) the broadest part of the face, or walnut-shaped frames that are not too deep or too narrow.

Round face:

A round face has curvilinear lines with the width and length of the face in the same proportions. To make the face appear thinner and longer, examine angular narrow spectacle frames to lengthen the face, a clear bridge that widens the eyes and frames that are wider than they are deep, such as a rectangular shape.

Long face:

The long face is longer than it is broad and has a long straight cheek line and sometimes a longish nose. To make the face appear shorter and more balanced, examine frames that have a top-to-bottom depth, decorative or contrasting temples that add width to the face or a low bridge to shorten the nose.

Square shaped face:

A square face has a strong jaw line and a broad forehead, plus the breadth and length are in the same proportions. To make the square face look longer and soften the angles, seek narrow frame styles, frames that have more breadth than depth and narrow ovals.

Heart-shaped shaped face or a triangle shaped face:

A heart-shaped shaped face has a very wide top third and a very small bottom third. To lessen the width of the top of the face, try on frames that are wider at the bottom, very light colors and materials or rimless frame styles.
