Is -450 same as -4.50 for glasses/contact prescription?!

Question: Is -450 same as -4.50 for glasses/contact prescription?

Yes, it's the same.

Sometimes we just don't write the decimal , but we know it has to be - 4.50


it's the same but it's still illegal to write an improper prescription. if you were buying pills and they filled it for 30 mg instead of 3.0 mg and you died. they would still be liable , even if they claimed they knew what they meant. falsifying a prescription is a federal offense and they could lose their license. no matter how chic they thought they were.
