Binocular vision has several advantages as compared with monocular vision. In this study, objective recordings of binocular functioning were studied with visual evoked potentials (VEP's). Lenses from plano through +1.50 D were added to reduce acuity monocularly and binocularly. Results indicate that the VEP, while sensitive to binocularly induced blur, does not reflect the changes in binocular vision which are produced by monocularly induced blur. The high contrast of the visual stimulus pattern (97%) may be responsible for the absence of attenuation during binocular viewing while one eye is blurred.
与单眼视觉相比，双眼视觉具有若干优势。在本研究中，利用视觉诱发电位（VEP）对双眼功能进行了客观记录。添加了从平光到+1.50 D的镜片，以单眼和双眼方式降低视力。结果表明，VEP虽然对双眼引起的模糊敏感，但并未反映出单眼引起的模糊所导致的双眼视觉变化。视觉刺激模式的高对比度（97%）可能是导致在双眼观察时一只眼睛模糊但VEP没有衰减的原因。
