Only one of my cat's eyes glow, could he be blind in the other one?

[SparklyGothKat]

We have noticed that only his left eye glows at night, no reflection at all in the other eye. Could he be blind or something in his other eye?

I had a blind cat his eyes glowed except the cataracts. My other healthy cat has a patch on her eye that doesn't glow but she has no eye problems as far as I'm aware

sounds like a cataract - ask the vet next time you go.

he is only 4.

My cat was blind and had cataracts from kittenhood - it does happen
