My eye get tired really fast when reading?!

My eye get tired really fast when reading?

I start reading and like after 15 mins my eyes start getting tired and want to close. If I keep reading my eyelids would get coldish. Does this mean I need glasses because I know some people can read a whole book and not be tired. If it helps I usually read out loud...DO I need glasses or what's wrong?

Does it really matter that I also usually read downwards?

you might need glasses and you might not. there could be multiple problems:

refractive error: you might be farsighted, or nearsighted, or have astigmatism

binocular vision problems: you might have problems "teaming" your eyes or using them together. you could be "aiming" inaccurately...esotropia or esophria, or exotropia or exophoria...

accommodative problems: you might have problems "focusing" your eyes.

you are likely going to need an eye exam to figure out whats wrong with you, and you may or may not need glasses.
