How deep is the focus, or can it be tweaked? Do you find it more tiring than traditional monitors or less?

Do you get dizzy?

The RayNeo Air 2 is the most barebones XR glasses I've seen. Barely adjustable and not enough IMO, but enough to work with if you use in large text and increase scaling.

Other brands like VITURE have more adjustments available, but the price will be double what I paid for the RayNeo Air 2 ($200). It looks like these are being heavily discounted in favor of the RayNeo Air 2s and future models.

I don't get dizzy at all while using them. :)
