Glasses with special lenses are used for vision correction, when its parameters are deviated from the norm. Depending on the nature of these deviations, spherical glasses (ordinary, Franklin, periscopic) are prescribed, prismatic, cylindrical, spherocylindrical, stenopic, color.
Selection of glasses for sight, types of glasses
Without glasses you can not do without:
- presbyopsy (age-related disorders);
- short-sightedness to -30 diopters;
- farsightedness up to +10 diopters;
- astigmatism up to 6 diopters;
- intolerance to contact lenses;
- impossibility to carry out refractive correction (operation).
When choosing glasses for restoration and correction of vision, first of all, pay attention to whether normal visual acuity remains and the ability to clearly see both eyes at the same time.
Important is the feeling of comfort when wearing glasses. Here the first important factor is the mobility of the nose-suits. Hard nosoporyra can pinch the bridge of the nose and cause discomfort, rapid fatigue. In addition, after them on the bridge of the nose there are traces. Therefore, give preference to glasses with soft silicone, mobile nosopurami.
The second factor is temples. Their size must be chosen in accordance with the distance from the rim to the bulge behind the auricle.
Perforating glasses, or goggles, are designed to relieve eye fatigue after intense eye strain, to protect against sunlight, and to partially restore visual acuity (provided persistent training).
Fashionable frames and stylish glasses for eyesight
Undoubtedly, you should like the frame and fit the shape of your face. To correctly choose the shape of the eyeglass frame for vision, be guided by the following criteria:
- If you have an oval or diamond-shaped face , then, most likely, you are the lucky possessor of optimal proportions. Therefore, any frame will emphasize your natural beauty.
- If your face is round , discard the rounded frames with smooth lines. You should focus on frames with sharp corners, rectangular and narrow. Do not choose massive frames. In this case, one should also take into account the shade of the jumper, - it should not be bright or dark. Ideally suitable transparent jumper.
- An elongated narrow face will visually correct the average width of the frame, but rather long.
- The triangular shape of the face , characterized by a broad forehead or too massive chin, can also be balanced by the shape of the rim. In this case, choose a bright frame, it will visually reduce the upper part of the face. A bright, with a decor, the frame "cat's eyes" corrects the proportions in the second case (wide chin).
- A square face (broad forehead and massive chin) will fix a narrow oval frame.
You can also visually correct some parts of the face. For example, if the nose is long, then choose a frame with a low jumper. If small and short - with high. Women with close-set eyes rationally choose glasses, in which the rim is wider on the outer edges.
