eye problem

My approx. 14 y/o male cat has developed a type of haze over his left eye that doesn't reflect light the same way as his right eye. There are also what appear to be blood flecks in the cornea and I noticed a white discharge yesterday. It doesn't seem to be bothering him. He's active and eating well. However, the redness seems to be getting more severe. He's been healthy so far, thank goodness.
   
Is it an infection?

It might be surely an infection. Please consult your vet as soon as possible.

Took your advice - vet said it's uveitis, no treatment required but to monitor for change in cat's appetite, behavior, etc. Thanks!
