盲点のレンズ効果に関する研究

Lens' influence on blind spot

　盲点に対するレンズ効果には色々の因子が関係する。

　〔実験I〕＋6D〜−10Dの間で2Dおきにレンズを選び装用した時の盲点径と盲点固視点間距離を測定し，夫々レンズなしの時に対する百分率で現わすと，装用レンズ度に対する変化は共に直線的である。

1) The use of lens (+6D- -10D) changed in a straight line both the blind-spot diameter and the distance between the blind spot and the fixed point. This result was compared, in percentage, with the change in the case when the lens was not used at all. And it was found that the regrresion coefficient of the blind spot diameter get larger and more unique in change than the one of the distance between blind spot and fixed point.
