Eyeglasses are lenses or prisms worn in front of the eyes to compensate for various defects of vision. The most common form of eyeglasses consists of a pair of plastic lenses in a metal or plastic frame fitted to the bridge of the nose. The frame is held in place by spring pressure on the nose or by temples, or arms that grip the head or hook around the ears. Eyewear with lenses made of a hard plastic is commonly used for reasons of increased safety and light weight.

Other forms of eyeglasses include those held in place by pressure on the nose, usually called pince-nez (French, “pinch nose”). Single lenses used to correct the sight of one eye, held in place by wedging in the orbit of the eye, are known as monocles. Glasses with a handle rather than temples, occasionally employed for reading, are called lorgnettes.

The lenses of eyeglasses are ground in the form of concave spherical lenses for nearsightedness (myopia), convex spherical lenses for farsightedness (hyperopia), cylindrical lenses for astigmatism, and prisms for defects of convergence. Frequently it is necessary to grind lenses in a combination of these forms to correct several anomalies at once. Bifocal lenses are used to give a different amount of correction for vision at a distance and for close work. The upper part of such lenses is ground for distant vision and the lower part for close vision, so that the user has merely to lower the eyes to read and raise them to look at distant objects. Trifocal glasses are bifocals that are ground with a center lens for intermediate distance.

Glasses are worn to protect the eyes as well as to correct visual defects. The colored glasses, or sunglasses, worn to protect the eyes against the rays of the sun are a familiar example. To protect their eyes from the actinic rays of welding flames, workers wear glasses of a deeper tint. Machinists and other factory workers wear glasses or goggles of great strength to shield their eyes from flying particles of metal, and aviators and racing drivers wear goggles to shield their eyes from the wind. Watertight goggles permit divers to see under water. Ski goggles help skiers with their sight as well.

Today, glasses do more than just correct your vision. They have also become fashion statements. For example, celebrities such as Elton John and Lisa Loeb are known for their ever-present eyewear. Ms. Jacky O. is also known for her signature large sunglasses that many stars now are still imitating, like Nicole Ritchie or Paris Hilton.

We all like our eyes keep their shapes of the age of 20. As the human body gets older, many physical and functional changes take place within it. A lot of these changes involve a decreased ability to perform tasks that once seemed basic. One of this obvious decrease is the eyes problem.

People rely on their ability to see throughout their entire lives. So when their vision starts to decrease, most of the people feel quite disappointed and helpless. It can be quite disheartening when this important sense no longer performs as it once did.

The problem of the aged eyes：

As the human eye ages, its cornea becomes hazy and the lens begins to absorb more light when people get older. Deposits in both the cornea and the lens cause an increase in light scattering inside the eye, making it difficult for a person to identify objects. In addition to a decreased ability to focus on an object, one’s ability to adjust to different levels of light is compromised.

Extensive research continues to be conducted to unfold the science behind regression of the eye’s functionality with age. Lighting industry leaders have taken notice of important findings regarding the role of lighting in vision enhancement, and in response have released product lines specifically designed to produce the type of light that counteracts some of the decreased visual ability that comes with aging.

Prevalence

The prevalence of prebyopia in low-and middle-income countries is not well known, as most studies of refractive error in these countries have been limited to distance vision. There are few presbyopia studies that have used a population-based approach, making it difficult to draw conclusions about the prevalence of presbyopia in the general population.

Impact

Presbyopia affects quality of life. This seems straightforward in high-income countries, where reading and writing are the main near vision tasks undertaken. For example, McDonnell et al showed that presbyopia was associated with substantial negative effects on health-related quality of life in a US population.

Interventions

While new treatments are being developed for presbyopia, glasses represent an effective, economic option for low-and middle-income countries. However, there is a little research on the determinants of, and barriers to, the use of near-vision glasses. We are still awaiting data on the availability and affordability of near-vision refractive error services, including a system for efficient dispensing of high-quality, affordable spectacles.

The majority of people in our study did not know where to get glasses. Among those who knew afford to travel to a location where spectacles could be obtained. In general, lack of knowledge about refractive services, poor accessibility, and additional costs (such as transport) raise further challenges for intervention programs. Websites such as Glassesshop.com are convenient and safe.

Just as eyes need our careful care, a pair of glasses can not do without our maintenance to function well. And taking good care of the glasses can also do goods to your eyes at the same time. Here is some useful information for glasses wearers.

How to wear: Never pick up the glasses by one hand which may damage the equilibrium of the frame, causing the glasses out of shape eventually. So the right approach is to pick up the frame by two hands and put on the glasses parallel to the direction along the cheeks.

How to fold: Remember to fold the left holder first because mostly the frame was designed according to the left leg. Always folding the right holder first may cause deformation of the frames.

How to clean the lenses: The most effective method is to use flowing water instead of napkins or soft cloths. After washing the glasses, hold the edge of the frame with one hand, and use the soap to rub the lens to get rid of the grease and dusts that stick to the lenses. Make sure to be gentle enough during the whole process.

How to place: When you are not wearing the glasses, please cover it with the cloth and put it in the case. Do not forget to place the glasses with the lenses’ side upward, for fear of the abrasion. In the mean time, avoid placing the glasses near corrosive chemicals like insect-resist agents, cosmetics, medicines and detergent. What’s more, do not forget to prevent the glasses from getting too much direct sunlight to avoid color fading and frame deterioration.

Adjust the glasses regularly: The frames may become deformed after being worn for a long time, causing extra pressure on your nose and ears. Thus, you’d better go to the optical shop regularly for adjustment and check.   

If you take good consideration of the approaches mentioned above, you may not only prolong the performance life of your glasses, but also protect your eyes at the same time.

how to choose women eyewear

As to a person who wear myopia glasses, the lenses would appear to narrow the eyes, so the eye make-up should be emphasized. May be drawing some dark eye line will expand the eyes. On the contrary, the traces of painted eyeliner would be weakened by the reflect action of the lenses. The purer color eye shadow the better because rich shades of color will weaken the image of the eye. Make up the upper eyelid in the edges with deep shades of coffee, and then a transition to the eyebrow slowly. You’d better use eye shadow with the same color depth changes, such as gradually from brown to deep brown and so on. Due to the frame and the lens, an additional content of the face, eye make-up must be relatively concise and simple. Volume dye eyelashes and mascara eyelashes is necessary for the short eyelashes, but if you own very long eyelashes, mascara would touch the lens easily to blur your vision.

As to a person who wear photochromic women eyeglasses, It is appropriate to powder the eyes with warm light or bright shades of pearl colors eye shadow, because changes in the depth of the lens will have an impact on the eye colors, such as the blue eye shadow will change into gray seeing from the reddish-brown lens into, and red will become brown. Another method is to delineate eyeliner only to make eyes more charming.

be in fashion by wearing a pair of glasses

If one just takes glasses as a kind of decoration, the make-up should be based on the changes in the frame. And the glasses can be used as decorations contrast with the quality of your image.        

When wearing a pair of small metal  eyeglasses frames, the make-up should be detailed, concise and simple. Brown eye liner or eye shadow to the tone is better. Pay attention to clean out the superfluous eyebrows, volume the lashes a little and brush on the black mascara. Wipe the lips with light orange, heliotrope, pink and red to show the elegant temperament.

As to someone who wears contact lenses should pay attention to that the make-up need be done after one had worn the contact lenses, or it will contaminate the lenses. And make sure every cosmetic you will use on the skin near your eyes avoid too greasy, or it may afflux into your eyes.

Every girl is a princess, whether you wearing a pair of glasses or not. But the key to remain as a princess is the knowledge of make-up. So every spectacle girl need to be trained to be a princess.

Actually, most instances of infection and injury to the eyes are a result of careless application and use of cosmetics rather than due to the ingredients. So it is especially important to follow some simple rules of cleanliness and hygiene when using eye-cosmetics. Wash your hands before touching your eyes; never borrow or lend any item of eye makeup; never use saliva or dirty water to moisten eye-makeup. These are so basic that you have to keep them in mind.

Choose Your Best Eye Makeup

Allergic reactions to eye makeup are however, not uncommon. The solution to this problem is to stop using the eye cosmetic which has caused the reaction. But, do remember, that reactions round the eyes are not always due to eye cosmetics, but maybe due to the nail varnish or the hair dye you have used.

The most important one of all eye makeup is the eye shadow. So I am going to talk something about how to choose eye shadows. The eye shadow you choose should flatter and enhance your eye color and the shape of your eyes, as well as your whole appearance. You should take your skin color, eye color and your lifestyle into consideration when choosing and using it. Always harmonize the color of the eye shadow with that of your skin and your eyes. Moreover, whatever the color, it should be blended in well, so that there are no harsh lines and get a natural look.

Apart from colors, you should keep the forms of the eye shadows in mind. Pressed powders are still the most popular form of shadows, because they are easy to apply and control. These are available in pearly and matt textures. Many girls worry that the effect is not long lasting, but if you apply them with a wet brush, you can solve the problem and get a deeper effect and increase the staying qualities of the color. Cream shadows are for your choice, they are oil or wax based suited for dry crepe lids and should be avoided on greasy lids.

Sticks and pencils are different. Sticks are firmer forms of cream shadow and look quite like lipsticks, while pencils have almost totally replaced sticks and crayons and have a high color and filling ability. Gels are suited for greasy skins which give a long lasting, subtle and translucent effect.

The last one is liquid shadow, which also have a long lasting effect, but are difficult to apply because it is difficult to get an even flow of color with them.

In the hot summer, prescription sunglasses have become our most intimate belonging. We could go out without a bag, but we could not leave out a pair of sunglasses. It is uneasy if we do not wear a pair of sunglasses—it seems that our self-confidence and courage may disappear at once. On one hand, in the psychological view, as we observe the sun through the lenses of sunglasses, we may notice that the sunlight become soft. On the other hand, sunglasses are useful to cover the tiring face owing to lack of sleep last night. Up to now, a pair of sunglasses could meet your need, however, if you want to make full use of the sunglasses fashion, a pair of sunglasses is totally not enough! We could learn something from Paris Hilton.

As for the material life of Paris Hilton, it is absolutely a absurd play. She is a famous playgirl, who owns sufficient money and fame. Her expenditure could be called dissolution and excess. In recent days, during a TV interview, Paris is invited to display her own room, including the rooms of clothes, hats, ornaments, and shoes. According to what Paris introduced, the clothes of her own brand have exceeded more than tens of thousands and she has one to two thousand of shoes, uncountable ornaments, and several hundrads of sunglasses. She also employs a private assistant to look after and clean these rooms. She deserves as a good example to match sunglasses with clothes.

It is generally believed that we should pick up a pair of prescription sunglasses according the face shape. For example, if your face is round, you should avoid buying round sunglasses which will make your face rounder; and if your face are long, the large sunglasses is suitable for you, because they could hide the deficiency of your face shape; but for the oval face, all kinds of sunglasses are right. However, the face shape of Paris is not very perfect. Hers is a bit square, with obvious bones and muscles; nevertheless, her face is quite small. Moreover, she is good at matching, so any type of sunglasses is nice on her.

Therefore, it is too general to say that we should buy sunglasses based on face shapes. According to the practical experience of Paris, her sunglasses have many types and colorful colors. In addition to that, she is confident and brave enough to wear any kind of sunglasses. Different kinds of clothes need the match of different sunglasses—this is a trend, so how could a pair of sunglasses be enough?

Invention of Eyeglasses--old style glasses

Many theories abound for whom should be credited for the invention of traditional eyeglasses. In 1676, Francesco Redi, a professor of medicine at the University of Pisa, wrote that he possessed a 1289 manuscript whose author complains that he would be unable to read or write were it not for the recent invention of glasses. He also produced a record of a sermon given in 1305, in which the speaker, a Dominican monk named Fra Giordano da Rivalto, remarked that glasses had been invented less than twenty years previously, and that he had met the inventor. Based on this evidence, Redi credited another Dominican monk, Fra Alessandro da Spina of Pisa, with the re-invention of glasses after their original inventor kept them a secret, a claim contained in da Spina’s obituary record.

While the exact date and inventor may be forever disputed, it is almost certain that spectacles were invented between 1280 and 1300 in Italy.

These early spectacles had convex lenses that could correct both hyperopia (farsightedness), and the presbyopia that commonly develops as a symptom of aging. Nicholas of Cusa is believed to have discovered the benefits of concave lens in the treatment of myopia (nearsightedness). However, it was not until 1604 that Johannes Kepler published in his treatise on optics and astronomy, the first correct explanation as to why convex and concave lenses could correct presbyopia and myopia.
