The Manufacturing Material and Lens Size of Goggles - 翻译中...
Eye shield goggles are glasses worn during sports or work. They are mainly used to avoid eye injuries caused by splashes, chemicals, infectious body fluids (such as droplets, blood, etc.) and strong light.
1. Manufacturing materials of eye shield goggles
When this lens is manufactured, a part of metal oxides such as iron, cobalt, chromium, strontium, nickel, manganese, and some rare earth metal oxides such as and neodymium are added to the general optical glass formulation. These metal oxides enable glass to selectively absorb electromagnetic waves in a certain band of light, such as cerium and iron oxides, which can absorb a large amount of ultraviolet rays. The use of this glass lens can reduce the amount of certain wavelengths passing through the lens to reduce or prevent damage to the eyes. Different colors of anti fog goggles can absorb light of different colors. This kind of glasses is divided into two categories, one is absorption type and the other is reflective type. The former is used the most.
The lens pieces are generally round, and the specifications are expressed in terms of their diameter. The unit is mm. There are φ48, φ50, φ52, φ56, φ60, φ65, φ70 and other specifications. The most commonly used specifications are φ56, φ60 and φ65. Due to the popularity of large frames, the use of large-sized lenses such as φ70 has increased.
2. The lens size of eye shield goggles
The size and shape of the spectacle lenses that conform to the shape of the frame after processing the rough piece are naturally determined by the curve of the inner edge of the frame. The lens of anti fog goggles should indicate the horizontal direction and the nasal side, otherwise the lens of asymmetrical shape will become a completely different shape after being rotated.
The size of the lens is expressed by the length of the reference line and the height of the reference line (reference line method), that is, AA'×B'B, in mm (for example, 46×40); or by the horizontal and vertical dimensions of the circumscribed rectangle ( box method).
The shape of the lens is represented by the difference in the shape of the lens. The so-called sheet shape difference is the difference between the length of the reference line and the height of the reference line (reference line method), or the difference between the horizontal and vertical dimensions of the circumscribed rectangle (box method). The unspecified is the baseline method. For example, a 46×40 lens has a shape difference of 6 (ie 46-40). The different lens shapes of some lens series are expressed by the difference of lens shapes. If the shape difference is 3 or 4, it is a tall shape. If the shape difference is 10, it is a short shape. Early lenses are symmetrical - round or oval.
A round eye shield goggle lens has a shape difference of 0, a short oval 4, and a long oval 9. The semi-circle is connected under the semi-ellipse to become a "wide field of view ellipse". In addition, there are "contour", "square", "edgeless" and "motion" and so on. The change in lens shape is mainly caused by the continuous refurbishment of modern eyeglass frames. Frames with different datum line lengths (such as 40, 42, 44, 46) can have the same plate shape difference 4 (eg 40×36, 42×38, 44×40, 46×42). But they are not proportional to each other, so the shape of the slices is also different.
