Laser in Cat's Eye

I like to play laser tag with my cat. I let the laser light reflect on the floor and wall surfaces, and he goes bananas trying to catch that little critter. A bad thing happened tonight, or at least I think it was bad, but perhaps it's nothing to worry about. I'll let you decide.

As I was pointing the laser beam over his head behind him, he moved his head up into the path and focused in directly on the beam. How do I know this? Because as the light entered a cat's eye, it illuminated a bright color. This is what the beam produced. It must have been close to a direct hit on the retina and once I knew what was happening I quickly jerked the laser light away (1/2 second exposure at most).

My question is if the brief episode of laser exposure is a permanent damage to the cat's eyes, or will the photoreceptors/retina, etc make a full recovery? I am very worried about this and we will from now on have to play other forms of tag that doesn't involve intense light.

Does he show any signs that it damaged his eye like excess watering half closed or closed all together.Or always rubbing it.

I haven't seen him yet since it happened. This was about 45 minutes ago. I just hope he didn't go blind. If he did, I'll never be the same, knowing I did something in some way cause harm to an innocent, whether it be intentional or unintentional.

Your cat's eyes are likely just fine.
Even though a laser can damage an eye, laser pointers are very low in output power.
If the exposure was for only a brief moment I don't believe you have anything to worry about.

Hi JD.

Here's what I found and it sounds like your cat should be fine.

Hello Newt,

Thanks for those links. I looked last night too for such info, but I kept dead ending. And thanks to everyone for helping to put my mind at ease. I haven't seen the cat since that incident, but then again he always disappears when the weather is above 90 and won't reappear until the sun sets.
