Q1: Why do I feel dizzy when looking at close objects? → This may happen if you're not viewing through the lower part of the lenses or if the prescription is incorrect. Try adjusting your head angle. If discomfort persists, Q2: Is slight blurriness at the edges of the lenses normal? → Yes. Bifocal lenses have a segmented design, which can cause mild blurring in the transition zones. This usually becomes unnoticeable after adaptation.
