首楞嚴義疏注經 2.450

2.450

色，燈光也。燈實有光，不曾有影，今見影者乃是眚病使之然也。以此而推，所見之影、能見之見俱為眚病。

'Color' is the light of the lamp. The lamp actually has light, never having had a halo; now seeing a halo is caused by the disease of the cataract. Inferring from this, both the halo that is seen and the seeing that sees are cataract disease.
