Definitions
- the present invention relates to shield type prescription glasses in which both eyes are covered with a single shield, and a method of manufacturing the same.
- shield-type glasses that cover both eyes with a single shield made of synthetic resin have been used mainly for sports because of their light weight and toughness, and they also have excellent upper fashionability.
- shield type prescription glasses in which a lens body for correcting vision is provided at a predetermined position in a shield.
- the conventional prescription glasses have separate shields and lens bodies, and are separately formed in through-holes drilled at predetermined locations on the shield (two locations facing the eyes of the spectacle wearer). Since the lens body was fitted or the lens body was adhered and fixed to the back of the shield, there was a risk of the lens body falling off and separating when subjected to a strong impact, which had a problem in terms of safety. . Disclosure of the invention
- the present invention has been made in view of the above-mentioned conventional technology, and in view of the problem that the safety must be improved.
- FIG. 1 is an end view of a horizontally cut portion of the prescription glasses according to the present invention
- FIG. 2 is a front view of a prescription shield used in the prescription glasses of FIG. 1
- FIG. 3 is a sectional view taken along the line AA of FIG. 2; BEST MODE FOR CARRYING OUT THE INVENTION
- the prescription glasses according to the present invention are made of a synthetic resin having excellent translucency and impact resistance, such as polycarbonate resin and ABS resin, and as shown in FIGS. 1 to 3, a shield 1 covering both eyes and The lens bodies 2 and 2a for correcting vision are physically formed.
- a synthetic resin having excellent translucency and impact resistance such as polycarbonate resin and ABS resin
- the shield 1 is formed into a curved plate shape with a convex surface on the front side, and the lens bodies 2 and 2a are located at two positions on the left and right sides of the back surface of the shield 1, that is, at predetermined positions corresponding to both eyes of the spectacle wearer.
- the surface of 2a has a concave shape or a convex shape as shown in FIGS. 1 (a) and (b).
- a shield substrate 4 having a convex surface having two convex portions 3 and 3a on the back surface is formed.
- the shield 1 is formed, an unnecessary portion of the outer edge of the shield substrate 4 is cut off, and a shield 1 having a desired shape is cut out from the shield substrate 4 (see FIGS. 2 and 3).
- the surface of the convex portions 3 and 3a on the back surface of the shield 1 is polished into a concave shape or a convex shape, and adjusted to a predetermined curvature to obtain the prescription shield 5 on which the lens bodies 2 and 2a are formed (first type). (See figure) o
- temples 6 and 6a are attached near the left and right ends of the prescription shield 5, and nosepieces 7 and 7a are further mounted below the center of the prescription shield 5 to form shielded prescription glasses.
- a dye may be mixed and dispersed in a synthetic resin for forming the shielding base material 4, or a lens body 2 or a dye added with a dyeing aid that enhances permeability may be added. What is necessary is just to immerse and color the shield 5 with transparency adjusted for the surface curvature of 2a.
- a concave groove is provided in the middle of the inner surface of a cylindrical type that can be vertically divided into two parts, A polarizing film is fitted in the concave groove, and a resin monomer is injected above and below the polarizing film to form a seamless substrate 4 having the polarizing film sandwiched between the front and back shields. What is necessary is just to cut out the shield 5 with a degree.
- the prescription glasses to which the prescription shield 5 is attached separately from the temples 6, 6a and the nosepieces 7, 7a have been described, but the temples 6, 6a and the nosepieces 7, 7a are attached.
- the shield base material 4 may be integrally formed when it is formed.
- the lens bodies 2 and 2a are integrally formed on the back surface of the shield 1, there is no dropping or separation of the lens bodies 2 and 2a, so that the eyeball damage due to the flying of the lens bodies 2 and 2a is avoided.
- the safety can be improved.
- the manufacturing process can be simplified, manufacturing costs can be reduced, and product delivery times can be shortened. Can be kept low.
- the shield and lens A step is formed at the boundary with the body, and the dust and the like accumulate on the step, which makes it easy to become dirty. ⁇ Since the product of the present invention has no step on the surface of the shield 1, it is difficult for dirt to adhere and dirt adheres. Can be easily wiped off.
- the shield 1 is formed in a curved shape with a convex surface, not only can a wide field of view be ensured, but also the foot feeling can be improved according to the shape of the head.
- the lens bodies 2 and 2a can be adjusted to have a desired power regardless of whether it is for myopia or hyperopia.
- the shield 1 and the lens bodies 2 and 2a are made of translucent synthetic resin such as polycarbonate resin and ABS resin, they are lightweight and strong, so they can be used in the sports field where they act violently. .
