Dark adaptation for testing visual acuity under mesopic conditions can be accomplished with Trendelenburg spectacles. The spectacle frames are in contact with the facial skin at all points, forming a light-tight seal so that no stray light reaches the eyes. The lenses are red filters, admitting no light below 630 nm. When these spectacles are used, adaptation can be performed in a normally lit room.
使用特伦德伦伯格式眼镜可实现用于在中间视觉条件下测试视力的暗适应。眼镜框架在所有点都与面部皮肤接触,形成不透光的密封,这样就没有杂散光到达眼睛。镜片是红色滤光片,不允许波长低于630纳米的光通过。使用这些眼镜时,可在正常照明的房间内进行适应。
