Description
【考案の詳細な説明】
従来レンズの後面と角膜頂点との距離計測法にわまず角
膜頂点とレンズの枠縁との距離を測り次にレンズの直径
を測りさらにスヘロメーターで眼側レンズ面の屈折力を
測ってレンズの凹みの深さを求めこれを前に計測した角
膜頂点とレンズ枠縁との距離に加えて求めるもので大変
複雑であった本案は眼前距離計を吸盤でレンズ前面に仮
固定雨垂直線で角膜頂点を測定角膜頂点測定位置に測定
板を仮設測定板とレンズ後面ＰＤ位置迄でメジャーにて
実測するので敏速正確に頂点間距離の測定ができる。[Detailed explanation of the invention] The conventional method of measuring the distance between the back surface of the lens and the corneal apex first measures the distance between the corneal apex and the lens frame edge, then measures the diameter of the lens, and then uses a schelometer to measure the refraction of the lens surface on the eye side. The depth of the lens concave is determined by measuring the force, which is then added to the previously measured distance between the corneal apex and the edge of the lens frame.This was a very complicated project. Measuring the corneal apex using a fixed vertical line Since the measuring plate is placed at the corneal apex measurement position and the actual measurement is made using a tape measure between the temporary measuring plate and the position of the rear surface of the lens PD, the distance between the apexes can be measured quickly and accurately.

レンズ後面と角膜頂点間を実測するのである。In order to achieve this purpose, this invention has 22 suction cups and 2 fixing grooves 4 on the upper transparent fixing plate 1, with reference lines 5 on the left and right sides, and moving grooves on both ends of the lower transparent moving plate 6, as shown in the drawing. 7 is set by inserting the transparent fixing plate 1 into the moving groove 7, passing the fixing screw 8 through the groove of the fixing groove 4, and superimposing the fixing screw 8 on the transparent moving plate 6. Transparent plate 9 with vertical lines and transparent plate 10 with horizontal lines at 2 mm intervals. A measuring plate 11 with a scale is temporarily installed between the transparent fixing plate 1 and the transparent moving plate 6 to actually measure the distance between the rear surface of the lens and the corneal vertex. .

を設は固定式でもよい。With this configuration, the front distance meter is fixed with the suction cup 2 at the PD position height of the eyeglass lens 13. When wearing the glasses with the front distance meter, loosen the fixing screw 8 and move the transparent moving plate 6 back and forth. Align both vertical lines 9' of the plate 9 with the corneal apex 14, fix the transparent movable plate 6 with the fixing screw 8, remove the eyeglasses with a distance meter in front of the eye from the wearer, and measure with a scale between the transparent fixing plate 1 and the transparent movable plate 6. Insert both ends of the plate 11 to the corneal apex measurement vertical line 9' and measure the distance between the apices by actually measuring between the rear surface of the lens 13 and the measuring plate 11 with a scale using a measuring tape 12. Also, attach a suction cup 16 to the transparent movable plate 6.
The installation may be fixed.
この考案は上に述べたように眼前距離計を吸盤でレンズ
ＰＤ位置にワンタッチセットにて光軸視線位置測定と両
垂直線にて角膜頂点を正確に合せる事ができる又簡単に
頂点間距離をメジャーで実測ができるので誤差が少なく
矯正眼鏡の医学的多大な効果があります。As mentioned above, this device allows you to measure the optical axis line of sight position and accurately align the corneal vertices in both vertical lines by setting the front distance meter to the lens PD position using a suction cup with one touch.It also allows you to easily measure the distance between the vertices. Since measurements can be taken with a tape measure, there are fewer errors, and corrective glasses have a great medical effect.
