The so-called protective glasses is a kind of filter, can change through the light intensity and spectrum.Avoid light radiation damage to the eyes, the most effective and the most commonly used method is to wear safety glasses.The glasses can absorb certain wavelengths of light, and let others through the light, so have a certain color, presented through the light color in color.One for absorption, one for reflection type, the former used most frequently.
The lens in the manufacturing, in the general formula of optical glass and add the part of metal oxides, such as iron, drill, strontium, nickel, chromium, manganese and some rare earth metal oxides such as neodymium and etc.The metal oxide can make glass to light some wavelengths of electromagnetic waves in the selective absorption, such as cerium and iron oxide can absorb a large number of ultraviolet light.Use this glass lenses can reduce the amount of certain wavelength through the lens, reduce or prevent damage eyes.Protection of different color lenses can absorb different color of light.The glasses is divided into two major categories, one for absorption, one for reflection type, the former is used most frequently.
Generally are round lens rushes, and specifications to its diameter, said the unit is mm, there are 48, 50, 52, phi phi phi phi 56, 60, 65, phi phi phi 65, etc.The most commonly used for 56, 60, phi phi phi 65 three kinds of specifications.Due to the popularity of the big picture frame, the use of large size lenses such as phi 70 increase.

The lens size folding edit this paragraph
Wool processing conforms to the frame in the shape of the lens, its size and shape of natural depends on picture frame around the curve.Lens should indicate the horizontal direction and lateral rhinotomy, otherwise the asymmetric shape of the lens after rotation will be completely different another shape.Lens size expressed in baseline length and line height method (baseline), namely AA 'x B B, unit for mm (such as 46 x 40);Or use the circumscribed rectangle horizontal dimension and vertical dimension (box).
Lens with sheet shape difference (shape difference).So-called shape difference, namely the baseline length and the difference between the baseline height (baseline method), or circumscribed rectangle of the difference of the horizontal and vertical size (box).Not specified for the baseline method.For example, 46 x 40

The size of the lens, its shape is poor is 6 (46-40).Some lenses series of different shape is to form pills.Poor shape for 3 or 4, is a high profile;Poor shape of 10, is a short form.Early lenses are symmetrical shape, round or oval.Round lens shape difference of 0, short oval is 4, oblong to 9.To connect semicircle under half elliptical become "wide-field ellipse" (Pantoscopic Round, Oval, PRO), has a variety of sheet shape is poor, shape to larger poor called "wide view" form.In addition to the "profile", "square", "endless form" and "movement" and so on.The lens shape change is mainly caused by modern glasses frame appeared unceasingly.Frames with different baseline length (for example, 40, 42, 44, 46), can have the same piece form 4 (such as 40 * 38 36, 42, 44 46 x x 40, 42), but not in proportion to each other, so form also each are not identical.
