A good lens Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses good decision The quality of the lens is the most important factor in determining the merits of a pair of glasses. There are four categories of lenses currently on the market: optical glass, ordinary resin sheet, high refractive resin sheet or PC lenses. Ordinary glass lenses are cheaper and scratch-resistant; resin and PC lenses lighter classes not fragile, especially the PC lens, you can get rid of the nose, such as rhinitis and headache pain caused by pressure, while the people who love the sport safer. From an aesthetic point of view, should choose a high number of high refractive resin sheet, but can also select high refractive glass. For drawing and frameless punch holder, resin lens more appropriate choice.
2, the weight of the frame as light as possible As a long time frame needed objects in our noses, we certainly have to consider its weight. The first is a high-quality glasses sturdy but lightweight. For people who are sensitive nose, choose lighter weight plates with or without borders frames are more in line with health needs.

In the United States, ophthalmologist optometry prescription is valid for one year, that is, myopia glasses every ones need to be re-optometry.
7, two glasses replacement Survey shows that people on average once every two years to replace the glasses. Ordinary myopia glasses should generally replace every two years, one to adjust the degree, the second is "replacement." Once scratched Cheap Mac Cosmetics Makeup wholesale Outlet glasses mirror, it will significantly affect the performance of optical correction, so regular maintenance and inspection of glasses, and timely updates, so that is always in good working condition.
The number of patients with myopia has reached 430 million, accounting for three percent of the population proportion. Among these, incorrect Tiffany and Co Charm Bracelet Jewelry Outlet glasses method, so that more patients with myopia increasing myopia. Available Optical Network experts have warned that the former should be possible to understand some of our glasses with glasses precautions to be assigned to a pair of the most suitable yourself, and do not hurt the eye glasses.
Note glasses are the following:
1, do a comprehensive medical optometry There are still a lot of people think that only need glasses optometry can, in fact, do a comprehensive eye examination is visual function with glasses considerations important step. Traditional optometry, only the most basic requirements of medical optometry Eye Hospital carried out, is not merely a degree of experience, but also to troubleshoot some teenagers susceptible to eye disease.
2, each time before re-optometry optician A lot of people make reference to their old optician Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, glasses directly, which is not correct. Optometry, is the focus of glasses considerations, many young people with the eye, refractive changes rapidly, the former optician optometry can learn the most accurate refractive status. And, not only is the correct determination of optometry myopia, astigmatism can understand other conditions, such as IPD. Also, children under the age of 16, the initial dilation glasses need to do after mydriasis, to be able optometry, purpose of doing so is to avoid pseudomyopia mistaken as true myopia, myopic children's self-fulfilling prophecy.
3, the choice of lens Many people choose lenses, just improvise based on the standard. The choice is with one lens glasses precautions, restless youth, regular physical exercise, you can choose resin lenses, this lens is lightweight, durable, non-friable; rather complicated for some refractive young people in need to customize lenses the best lens case can be customized to fit into a pair of the most suitable Fake Oakleys Gascan Sunglasses Cheap for Sale glasses.
In the myopic glasses when Fake Oakleys Frogskins Sunglasses Cheap for Sale lenses are to a large extent affects the eyes a future vision, will also have protective effects to the eyes, it should be how to choose lenses? According to the basic material of the lens, and other factors to choose lenses.
Methods/procedures When choosing a lens, taking into account the degree of applicability and suitability factors such as myself, to choose the right lens. Selecting glasses to four: Seeing glasses whether made glasses production permit; Two optical corporate optometry equipment and testing equipment has conformity mark; Three, optometry, producers are in charge; Four glasses without a tag ().
Lens material: Cheap Ray Bans Wayfarer Sunglasses Outlet Sale glass lens; resin lens; PC lenses; Glass lens refractive stability, good resistance to abrasion, optical performance, but heavy, easily breakable. Glass lens: refractive stability, good resistance to abrasion, optical performance, but heavy, easily breakable. Tree Resin lenses (CR-39): light, safe, and high rate of transmission, is not easy to break, but easy to wear. PC lenses: high refractive index, sturdy, but easy to wear.
Select lenses for accurate eye test: Best choice of hospital or optometry is big glasses shop. Eyeglasses for the first time, and if you are under 35 years of age, the Mydriatic refractometry. Old people should wear Cheap Mac Cosmetics Makeup wholesale Outlet glasses optometry, not freeloaders from its buy mirrors so as not to cause damage to the eyes. After the optometry, consumer 15-30-minute exam, myopia, hypermetropia wearers should Dai Jing to take walks, up and down the stairs; reading glasses wearers should read, reading a newspaper.
If feeling unwell, and optometry staff, please adjust the lenses in a timely manner, until satisfied. Buy high myopia lenses of high refractive index n=1.70, 1.80 or 1.90 (this refers to glass lenses. Resin glasses tablets currently Supreme refraction rate is 1.74), to reduced lenses of thickness, and should not be purchase discoloration lenses; children should be purchase optical resin lenses, to guarantee wearing of security; general myopia patients should be distribution slightly red of optical red tablets or slightly blue purple of optical can Division tablets, to guarantee blocking most UV on people eye of against; water Shang job who selection Tiffany and Co Key Necklace Jewelry Outlet polarization King tablets. To increase light transmission and improve visual clarity, plus optional film lenses.
1, do not wear Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, preferably on the mirror box. Do not touch the surface of the lens with hard objects, with particular attention to the legs in the air do not mirror, mirror face down.

2, lens cleaning is best washed with water, dishwashing detergent behind 1-2 drops, washed rinse with water, dry or dry with a soft towel.
3, with a special resin lens fiber lens cleaning cloth, lens cloth, wash with water. In particular, be careful not to wipe it with a hard cloth or clothes.
4, should develop the habit of wearing hand pick, pick a long-term one-hand frame glasses can cause gradual distortion, resulting in skewed even different sides of the Fake Oakleys Gascan Sunglasses Cheap for Sale lens mirror tilt, leaving mounted shifter, there prism effect - affect vision, vision fatigue. Caused by long-term, unaware, aggravated vision loss. Frame too loose, but also allows the optical center and the pupil dislocation, resulting in a prism effect, and cause visual fatigue.
Over time, accustomed glasses askew, re-interchangeable lens, glasses may produce fully qualified but cannot accept. Especially young students wearing progressive multifocal lenses for myopia prevention and because of the need to use a mirror while wearing near elderly should be noted that due to the use of effects and frames norms progressive multifocal glasses have a very close relationship.
5, regular inspection, if found frame twisted, damaged, should go to the optical shop for a professional repair, correction.

More scratch-resistant glass lens with the lens characteristics than other materials, but the relative weight are more heavy, relatively high refractive index: 1.523 ordinary piece, thin piece: 1.72 or more, up to 2.0. Polymer resin lenses: polymer resin lenses are lighter than glass lenses, impact resistance not broken, but because of its low hardness, it is more prone to scratches than glass.
2, PC lens
There is also a material that is more resistant to impact than the polymer resin, often transparent windows for aviation Cheap Mac Cosmetics Makeup wholesale Outlet equipment, police on masks, and masks astronaut's helmet on, it is only about one tenth of the weight of the glass with the traditional compared resin lens is only half the weight.
PC lenses generally need to add anti-scratch protection film after, in the use of time would be enough to get better, most used in children's glasses, or goggles athletes. PC lenses also have an important feature that PC lens with isolated harmful UV effects, but its disadvantages are also included surface easily scratched.
3, bifocal lenses
Bifocal lenses can be simultaneously corrected distance visual acuity and the last two were mainly for the time required for correction of presbyopia. General bifocal lenses allocated as follows: the upper lens is to see the distance, the lens is used at low use of near point of view, as the near range of the size, depending on the nature of the work to set near by.
Probability is used generally flat top bifocal, they are only a small area at the bottom of the lens as a near point of work, as the periphery of the upper portion of the lens is used with a remote monitor good peripheral vision. The traditional bifocal Tiffany and Co Key Necklace Jewelry Outlet lenses to line bifocal lenses, lens down into two parts by the middle, which is less than half of all lenses used as a near point distance, they provide a better wide near point vision for a long time workers at near point have a better effect, architects, accountants, and other artists who work close to nature, such lenses can reduce the chance of head swinging. Bifocal lenses can also be used in only just read the required correction to the near point, but not in the near point work actually put on glasses to take to win.
4, three-focal lenses
For those in need of vision from the people (usually about from 18 inches to six feet), as far and near in general, the use of these three focal lenses to meet the needs of those people in front of a computer or cash register work for this vision in the distance with special needs, such a vision lenses to meet the needs of his work.
Corrective lenses are also the effects of these comprises a plurality of ranges, the type of lens is different between each piece of the boundary is not obvious from these boundary multifocal Cheap Ray Bans Wayfarer Sunglasses Outlet Sale lenses may need close to the place, or can be seen touch by hand can feel, but when the user near to far from the conversion, the eye will still be felt large sudden changes.

Which is good so highly myopic lens, which is characterized by high myopia talk from friends.
Highly myopic lens which is good, from the following aspects.
1 as possible for the lens refractive index of 1.60 or greater
Is the refractive index of the lens of the light turns capability shows the main parameters of the lens thickness, the current market is the refractive index of the resin lens is generally between 1.49 to 1.74, the higher the refractive index, the thinner the lens, in general, more than 1.60 called thin lenses. So, for people with high myopia, it should choose the refractive index of 1.60 or more lenses. In addition, 1.8 or 1.9 high refractive index glass lenses are also a good choice for patients with high myopia and thinner than resin lenses, but there have been no high-index lenses several domestic production, so they need to customize, the price is not cheap, especially. Also need to be reminded that resin lenses with half-frame Fake Oakleys Frogskins Sunglasses Cheap for Sale glasses, rimless glasses with a more stylish appearance, but for patients with high myopia, it is not recommended with rimless glasses, otherwise the lens look thicker.
2, try not to choose glass lenses
Once dominated the glass lens is the lens material on the market, but with the drawback of glass lenses highlights: fragile, hidden dangers, lens weight, easy on the ear or nose patients formed indentation on young children, in particular, is not easy accepted. Later, the emergence of resin lenses, resin lenses (including the PC universe piece) lens material is a revolution, not easy to form with a light texture indentation, non-friable safer, high temperature, wear comfortable, etc., to get along with resin lenses widely used, glass lenses also slowly withdraw from the market, and the high prices. For safety, youth also choose the best high myopia resin lenses.
3, RGP is a better, more perfect choice
RGP is a rigid gas permeable contact lenses, is more than 600 degrees of myopia and do not want to wear glasses is an ideal choice for patients with high myopia, compared with ordinary wear glasses, RGP image clearer, so that the wearer has wider field of view, better visual quality and fewer constraints. For young students who, Fake Oakleys Gascan Sunglasses Cheap for Sale can effectively control the growth and the correction of high myopia astigmatism, irregular astigmatism.

Lens Material: Glass Lens; resin lenses; PC lens; The refractive index of glass lenses stability, good wear resistance, stable optical performance, but relatively heavy, easy to break. Glass lenses: the refractive index of stability, good wears resistance, stable optical performance, but relatively heavy, easy to break. Tree Fat lenses (CR-39): light, safe, high transmittance, not easy to break, but the surface is easy to wear. PC lens: high refractive index, strong, but the surface is easy to wear.
Select the glasses to be accurate optometry:
The best choice of hospital or large glasses shop for optometry. Initial glasses and if below the age of 35 should be dilated optometry. The elderly should also wear Tiffany and Co Key Necklace Jewelry Outlet glasses optometry, not freeloaders from the flea market to buy a mirror, so as to avoid eye injury. After optometry, consumer’s exam wearing 15-30 minutes, myopia, hyperopia lens wearers should be wearing glasses to go walking up and down stairs; reading glasses wearers should look at the book, read the newspaper. Any discomfort, please promptly adjust the lens optometry personnel until satisfied.
High myopia should buy a high refractive index n = 1.70,1.80 or 1.90 lenses to reduce the thickness of the lens, and not buy photochromic lenses (which refers to the glass lens resin glasses highest refractive index is 1.74.); Children should optional optical resin lenses, to ensure the safety of wear; generally advised in patients with myopia optical slightly red or bluish purple red chip optical film can be Secretary to ensure that block most ultraviolet radiation on the human eye infringed; water King polarization operator selected pieces. In order to increase the light transmittance, improved visual clarity, optional coated Fake Oakleys Frogskins Sunglasses Cheap for Sale lenses.
