The lenses may be ready before your brain is. A few things can feel different while the two get acquainted.

A new progressive prescription can change how peripheral areas of the lens feel at first.
Progressive lenses combine different viewing zones in one lens. At first, the floor can feel slightly off and peripheral vision may seem different while your brain figures out where to look.

Consistent wear gives your brain time to adapt to the different viewing zones in progressive lenses.
Going back and forth to your old glasses can make adaptation harder. Regular wear gives your brain a better chance to settle into the new lenses.

Progressive lenses include an intermediate viewing area for distances such as a computer or work surface.
Looking sideways can take some practice. IRIS recommends turning your head toward what you want to see and being extra careful on stairs during the first few days.

If new progressives still feel significantly uncomfortable after an adjustment period, the fit and prescription are worth checking.
Some people adjust quickly; others need days or a few weeks. If significant discomfort sticks around, have the fit and prescription checked. Sometimes the fix is simply an adjustment.
