Adjustable Focus Dial Vision Glasses vs Flex Focal Adjustable Glasses

Both are dial-focus glasses with weak owner feedback, so treat them as a cheap experiment rather than a vision solution. The tianyuezhaomingkeji pair covers a much wider range, from -6.0 to +3.0 diopters, which makes it the only one of the two that can help a nearsighted wearer. The Flex Focal pair is a partial-rim reader aimed at close work and ships with more accessories. Ratings sit at 2.4 and 2.2 out of 5, so neither earns a strong recommendation.

• Choose the tianyuezhaomingkeji adjustable glasses if you are nearsighted or want one pair to cover both distance and reading, since its dial spans -6.0 to +3.0 diopters.
• Choose the Flex Focal Dial Vision if you only need help with close work and prefer a partial-rim frame with a visual chart, cloth and storage box included.
