Every time I read one of these, especially if it's a first post, I always think there are some people that just shouldn't be allowed to handle a laser or anything else that's dangerous.
Any laser over 5mW is too powerful for your blink reflex to save you and can do damage. I have heard of someone taking a direct hit in the eye with a 40mW without permanent damage however at that power there would usually be permanent damage.
532nm green lasers also put out IR and the cheap ones never have an IR filter, so they are even more powerful than you think. The worst that will happen is you will have a permanent dark spot in your vision, in the best case your eye will be back to normal very quick.
Go see a doctor and tell them you got a direct hit in the eye with a 30mW green laser, your regular doctor can refer you to an ophthalmologist or you can see an optometrist and they can tell if there's damage and can refer you to an ophthalmologist.
