How to choose sunglasses
Material shall be a primary criterion in choosing sunglasses, because health is more important to the style or image. Glasses not only help protect your eyes from bright sunlight, but also do not allow UV light (only glasses with glass lenses). Just wanted to say that too small glasses (whether glass or plastic) though will look stylish, but will be a poor tool in sun protection.

Sport, recreation and sunglasses
For sports sunglasses special requirements. They not only must reliably protect your eyes from the sun, but have increased strength, to be made of special plastic, not glass, because glass increases the risk of eye injuries. According to statistics, 90% of eye injuries could be prevented if protective eyewear, with nearly half of all injuries occurring in children under 14 years.

How to choose glasses for a child?
In the first year of life, the main indications for correction are aphakia and high myopia. In children under the age of three leading indications for correction of hyperopia is for esotropia. Preschool children (3-7 years) to correct aphakia, congenital myopia and hyperopia are added early acquired myopia and astigmatism. At school age, the leading indication for the correction of myopia is acquired.

How to pick the right rims of the glasses?
New Year - the right moment to change the old, familiar, or start something new. For example, you can radically revise its image, or even just thinking about it. Think we'll start with the principal, and most importantly to us, loved ones, of course, the eyes, and everything associated with them.

What you need to remember when choosing a frame for glasses?
Participation points is a fairly serious procedure. Many people, especially women, are choosing to purchase the frames as a costume or decorations. The frame should be modern, "trendy" and yet have to face, color and styling your hair, and jewelry.

Improving appearance points lenses
Vysokoprelomlyayuschie lenses made of organic materials can significantly improve the appearance of spectacles. Using the lenses of materials with refractive indices from 1.60 to 1.74 can substantially reduce the thickness and weight of lenses and glasses to make a superficially more attractive, even at high degrees of ametropia. Variety vysokoprelomlyayuschih range of lenses in combination with optical coatings, which offer today, many manufacturers, often puts consumers in a quandary: what lens to choose? To make the right decision, we must understand the basic characteristics and features of the lens material with high and superhigh refractive index.

Contact lenses
It is believed that the eyes of the lens blush, "dried" lacrimal gland, eyes acquire a specific shine (not the greedy, not that ravenous), triggered by a myriad of diseases and so on. I wear lenses for more than 4 years. With regard to shine in the eyes and other cosmetic effects of the MCL, then I am with my close friends spent the experiment: one in the eye lens, the other without.

Spectral points or more on computer vision syndrome
American Association of optometric studies published data on the new occupational disease "Computer vision syndrome" - (KSZ). Computer vision syndrome in one form or another is observed in 100% of computer users. His symptoms are familiar to almost everyone who holds the monitor more than 4-5 hours a day. Ophthalmologists note the rapid growth of cases of SGC. For example, in North America with typical complaints of the SGC to the doctors turned to 1992, 10 million people. In 1996 - 15 million people., And in 1998 for 22 million people.

Polarizing eyeglasses. What do they differ from ordinary sunglasses?
Although the cost of those and other quite comparable, but the fishing is desirable polarized glasses. How to check whether the data points polarizing? Very simple. Take two pair, and lean their glasses to each other. You will be able to see through them. I now turn to some points by 90 degrees. If you continue to see through the glass, then the conventional glasses, but if you do not see - that's all right - you are in the hands of polarized eyeglasses. What it does affect fishing?

Sunglasses - Accessory enigma
The bright sun is often the cause of the appearance of wrinkles. On clear summer days, it is impossible to watch without squinting his eyes, especially if it is near sea. Sunlight reflected by water, shine in mercy. The only salvation in the hot, cloudless days are the sunglasses.

Sunglasses for drivers 

Road safety depends on many factors: the technical parameters of the car, proper operation of all its systems and units, experience driver, road quality, weather conditions and so on. And not least when it took visual acuity man sitting down for wheel. On how well the driver sees the road, the surrounding space, oncoming cars, pedestrians, and it depends own and another's security, and sometimes life. 

For the driver of great importance the central and peripheral vision. The main indicator of central vision - his remark. If the sharpness is lowered, the eyes perceive images of objects and objects in a distorted form. To compensate a little optical distortion, the optic apparatus automatically begins to strain. This leads to fatigue the eyes and all organism, decreased attention and concentration, which, in turn, increases the risk of emergency on the road. Peripheral vision defines the space that is simultaneously perceived by the eye with a fixed gaze. Naturally, the field of view has its limits, and wider than it is, the more space covers the eyeglasses. Narrowed field of view for driver is dangerous - he could not help noticing outrunning a car or a pedestrian. 

Most of the visually impaired, interfering feel comfortable behind the wheel, can be corrected with glasses or contact lenses. When choosing frames to remember a few rules. First, it should not restrict the field of view, so it's best preferred frame with a narrow bezel and narrow earhook. Better if Temples are not attached to the middle and the top or bottom part of the frame. This frame will provide a wider angle side and rear view. Secondly, for driving a car is not suitable frame, with narrow light apertures - it limits the field of view of the temples. In addition, the driver has good vision panel, not lowering, and not turning his head. But the skylights should not be overly broad, especially if they mounted mineral lenses with a large number of diopters. Such lenses are much heavier glasses, that is inconvenient for wearing, and their edges distort the image. Thirdly, the glasses should be as convenient as possible. If the frame is too heavy or small this creates a feeling of discomfort, forcing the driver nervous and distracted. In addition, the glasses should not put pressure on the nose and whiskey - squeezing of these areas may provoke a breach of blood flow, headaches. Too large frames will permanently move out from the nose, it will often correct, that does not help the focus of attention while driving car. Maximum comfort can provide a frame, nosoupory and Temples which are made of silicone or rubber. 

With regard to ophthalmic lenses, then there can say one thing: the optical qualities of glass and plastic lenses are almost identical, so in the first place should be put safety. And in terms of safety for drivers and better choice for stop polycarbonate plastic - a lens from it more resistant to mechanical impact, bumps less traumatic, because it does not break up into fragments. It is important that the glass lenses have antireflective coating, which transmits more light. 

In addition, it reduces glare.

This is interesting:
Optics remind drivers that glasses with coated, even the most expensive and quality, should be kept clean. Grease, dust on the lens significantly reduces the effectiveness of such points, and this increases the risk of an emergency. If the driver prefers dark glasses, then it is desirable to choose a lens with a yellow, gray, green or brown tint. They do not violate the color reproduction, better contrast and sharpness, improve visibility in bad weather, less straining their eyes. An important nuance: tinted glasses is permissible to use only during daylight hours. When driving in the evening and at night they better not to wear - they reduce the anti-glare effect. 

In recent years, many countries have become extremely popular to use sunscreen Clips points. They are good that combine the properties of corrective glasses with protection from ultraviolet radiation. In addition, they are cheap, functional, easy to use and compact. When necessary, the driver simply attaches clips to eyeglasses with diopters, that simultaneously allows him to see well and to protect their eyes from the too bright light.
