High plus lenses may cause defects in the peripheral visual field. Simple full vision lenses or lenticular lenses without a masked transition zone caused an absolute ring scotoma in the mid-periphery. Patients who were glasses of this type cannot see well enough to drive safely. Although modern edge finishes with masking of the transition zone reduce this problem, visual disturbances in the periphery of the lenses cannot be completely eliminated. A recommendation recently issued by the German Ophthalmological Society concerning maximum lens powers for motorists is aimed at preventing visual field defects of this type.
高度数凸透镜可能会导致周边视野出现缺陷。简单的全视镜片或没有遮蔽过渡区的双凸透镜会在中周边区域造成绝对环形暗点。佩戴这种类型眼镜的患者视力不足以安全驾驶。尽管现代带有过渡区遮蔽的镜片边缘处理方式减少了这个问题,但镜片周边的视觉干扰仍无法完全消除。德国眼科学会最近发布的一项关于驾车者最大镜片度数的建议旨在预防此类视野缺陷。
