Fake Oakleys
here is the main material of the lens, it contains the following five categories:
1 thanks to Lectra (toric)
This lens is also known as the white tray, white tablets, optical white tablets, which is an essential ingredient, sodium silicate, Titanium is colorless, higher resolution, 330A-absorbing UV radiation. Bai Tuo, Ceo2, Tio2 can prevent UV 346A, also known as white UV film. Visible light is the 91-92%, refractive index of 1.523.
2, Crocker
Commonly known as chip, the light transmission rate of 87%. These lenses are a two-color effect, pale blue under sunlight (also known as blue-chip), tinted Windows, a red bulb (neodymium-containing metals) under ultraviolet absorbing part of the yellow 340A and infra-red can be seen after the 580A.
3, Crocker race
Commonly known as the Gram game add Ceo2 and Mno2-Bai Tuo lens materials can improve the ability of ultraviolet absorption. This lens has a faint red bulbs, and it is also known as red. The ultraviolet absorption, light transmission rate of 88% in 350A.
4, super thin slices
These lenses have the raw materials, the increase in the refractive index of Tio2, 1.7%. A high albedo, as well as in the ordinary course of a diopter is a white or Red Hill thin one-third for wearing in high myopia, aesthetic appearance. Due to the low number of Abbe chromatic aberration, super thin slices can easily lead to lower your peripheral vision, color appears when the line curves.
5 glass lens
The refractive Index of the lens, 1.6, compared with ordinary glass lenses (1.523) thinner and relatively thin lenses (1.1) the share of smaller, so it is very easy to use, ideal for wearers, some manufacturers say the super simple and super thin lenses.
Reading glasses, also known as the old glass spectacle eye glasses optical products such as hyperopia class convex lenses. It is the same as the buyer will be able to identify the appropriate glasses style and color alone will not be able to buy. Reading glasses uses a complementary vision, seniors, like many national standard myopia Optical display, there are specific rules.
Reading glasses are mostly dedicated to the needs of the public eye. Presbyopia is a normal physiological phenomenon, not the eyes, not the elderly. After the age of 40, the human eye lens fibers of the ciliary muscle paralysis hardens gradually, gradually, that the human eye cannot effectively in the shape of the eye (axis Change), then just set the distance between the objects and the objects in the vicinity of the eyes must be moved to see clearly eye condition known as presbyopia. Normal distance Visual acuity hyperopia need to wear reading glasses again pretty much clear vision, literally speaking, reading glasses, entering middle age after the second pair of eyes for everyone. Reading glasses, people used to improve the quality of life is important.
Reading glasses on the market can be divided into two types: single lenses, progressive lenses and, in essence, reading glasses, reading glasses. The former is a standard used to say: "reading glasses", offers one, only to see almost everything you will need to wear glasses, the price is relatively cheap. In the second, progressive lenses, Multifocal lenses for reading glasses or bifocal, gradient, or even rolled into one, for example, to correct nearsightedness, farsightedness, glasses, a "mirror" feature.

8/4/2013 - Good reading Fake Oakleys glasses meet the requirements of optical |
Good reading Fake Oakleys glasses meet the requirements of optical, price tags, and comfortable to wear. This is reflected mainly in the following aspects:
1. should be fairly wide, due to the hyperopia succeeded late collections, along with reading writing habits, monocular Visual axis of the lens, how far from the (head), moves up to 2.5 mm in the movement. And head, usually in the middle of the pupil, and so on, which must meet the vision reading glasses, the height is greater than 30 mm-not less than, the better. 25 mm narrow gauge usually portable, temporary additional vision.
2. positive broader specifications, but OCD (horizontal distance from the optical Center) instead of smaller. Using reading glasses in the middle of reading glasses, busty, face-frame size large 10 mm, the level of the General optical mirrors, but hit near as far away from the small 5 mm hit, so the value should be, in General, women with OCD 58-61 mm, and men 61-64 mm, while those two, larger diameter lenses, and the manufacturer, be more light hearted moved to volume.
3. reading glasses. Sightedness, eye glasses pattern on the reading distance (+ 1 D 100 degrees) for 40 years, from the age of 5 D + 0,50 €/year (50). Frequency of reading glasses myopia, so choose an outfit and dozens of parts during use is a significant or very flexible material. Plating anti-corrosion anti-scraping performance excellent, difficult process to ensure a better lens, usually without serious irregularities, no rust, no serious spending over 2 years. In fact, several parts of the requirements on good reading glasses in the same classes as the frames of eyeglasses.
The elderly how to buy reading glasses?
The right to buy reading glasses is very important for those who need to wear reading glasses. Reading glasses, which with the principles, clean and comfortable, simply never considered the factor of price, just buy the sunglasses on the street, and more. Because presbyopia is not the same for everyone, the degree of reverse eye may or may not like it, myopia, astigmatism and other vision sightedness problem, if it is not suitable for reading glasses to wear for a long period of time, while others are not only does not solve the problem, it can also cause swelling of the eyes, headaches and so on. Only Official Optometric and optical shops just reading glasses, which corresponds to the vision is really to ensure eye health, the best in personalized, reading glasses, which are exclusive to their actual situation.
