Top Commitment of Ogura Optician Technology based on Quality of Vision The first is to improve eyesight. Accurate measurement is the basis. It is important to measure in a more stable state of adjustment by accurately grasping the interrelationship between adjustment and convergence that occurs in binocular vision and the viewing distance . Also, eyesight is subjective. For example, even with glasses that can obtain the same 1.0 visual acuity , if the visual acuity of the glasses used before is 0.5, it will be "too visible", and if the naked eye vision is 2.0, it will be "difficult to see". Please see the figure on the right. It bleeds, looks double, and the contrast is not clear, but you can see that the break in the ring is "right". It is also important to select a lens that takes into consideration the contrast and glare of the light that enters the eye . There are also individual differences in adaptability. For example, if the power difference or lens type of your new glasses is different from that of your current glasses, it may take some time to get used to the change immediately . Therefore, in the wearing test, we will compare the appearance with the glasses you are currently using and confirm each other. The second is reduction of tired eyes (reduction of eyestrain). "I have 1.2 eyesight" "I can read newspaper letters" Still a symptom of eye strain. It is caused by a slight imbalance in visual function that puts a strain on the brain. There are four types of eye strain that can be improved with glasses. 1. Visual eye strain 視環境とレンズ度数およびレンズタイプが合っていない 2.調節性眼精疲労 近視の過補正、遠視・乱視・老視の未補正 3.筋性眼精疲労 斜位と融像性輻湊とのアンバランスが原因 4.不等像性眼精疲労 左右の網膜像の大きさの違い 両眼でハッキリ物を見ようとするため、無意識のうちに脳が調節努力をしてしまい、疲れやすいといわれています。通常の視力測定だけでは、この軽度なアンバランス状態がどうかは、残念なから検出されません。 そこでオグラでは、一人ひとりの視環境に合わせて、４つの観点（視力／調節／両眼視／輻湊・開散）及びその関係性から、脳に負担をかけない、ストレスフリーなメガネをご提案いたします。 メガネは正しい位置に調整されていないと、ボケや度数誤差が生じ、これが違和感となって脳に負担をかけてしまいます。 特に、非球面設計レンズは、そのレンズ性能を発揮させるために、お一人お一人に合わせる調整技術（フィッティング）が不可欠です。 メガネの調整(フィッティング）は、3つの観点で行います。 美的観点 お顔とメガネのバランスは 1.フレームのサイズ と 2.フレームのお顔に対する 上下位置との関係で考えます。 1.フレームのサイズは顔幅と眼と眼の間隔を基準にして選びます。 2.フレームのお顔に対する上下位置は黄金分割になる1：1.6の所が美しく安定感も得られます。 光学的観点 In order to achieve 100% lens performance, it is essential to correctly align the positional relationship between the eye and the lens . Adjust so that the horizontal, vertical, and front-back positions with respect to your face are appropriate. Distance between the eye and the lens (distance between the apex of the cornea) Direction of the lens with respect to the eye (forward tilt angle) (warp angle) Position between the eye and the center of the lens (eye point) Mechanical perspective Fitting is also important for comfort. Most of the glasses are supported by the pads. The key to pad fitting is how to distribute the weight of the glasses . In addition, the point of fitting the temple part is how to give a force that pulls the glasses backward . The prescription for glasses is the same as the prescription for medicine. In order to reproduce the frequency with high accuracy, Ogura has set its own standard of perceptual quality, which is stricter than the industrial standard (ISO standard). privacy policy Contact Us site map Copyright © 2014 Ogura Inc.
