There is no way to answer any of this here, you need to go and get your eyes tested.

No one should be guessing about your need for glasses. You need to see an eye doctor and have your eyes examined. There are a lot more things involved with your eyes other than how close or far you can see.
Go get a proper exam.

no one can answer that here, you need to see an ophthalmologist to get an eye exam and a proper prescription.

Go and have your eyes checked to find out.
