Which lenses should i choose for my prescription glasses?

[glasses shop]

Since this is the first time for me to buy prescription glasses from the online optical shop, when i facing so many lenses options, i don't know which one i should choose. The online stores provide 1.49, 1.56, 1.61, photochromic, bifocal and so many other kinds of lenses. I only have problem in seeing things far away, i can see the thing in near distance quite clearly. Besides, my Rx is very low, only -2.00 for both eyes. What kind of lenses should i chosoe? Thank you!
