Some more anecdata: The lenses' coating from my cheap unbranded glasses (plastic lenses) have begun to disintegrate/separate from the glass. My other glasses' Zeiss lenses are fine still (both being 8 and 6 years old).
Other than that, to the OP: get what you like, if you need the super thin lenses (depends on your level of myopia), go with the expensive stuff, else the cheaper lenses will also work. The more expensive coatings will filter more reflections, do you need a polarizing screen (doesn't work well with LCDs though)?. Then there's the lens material: glass (more scratch resistant) vs plastic (safer, because shatterproof). If you need two zoned lenses thats also different, and way more expensive.
Edit: oh and make sure that the eye distance is properly measured (i.e. at all), that is to make sure that the optical center is ligning up with your eye

This also depends on the frame OP wants to go for. With thicker frames, thicker glasses tend to be less of an aesthetic issue than with very light, transparent of frameless designs.
