I believe the first pair of reading glasses I had, which I got because my eyesight was failing, had a strength of 1.2. I bought them at Megane no Miki. The frame is Ray-Ban and weighs only 19g (including the lenses). It's so light, I don't even feel like I'm wearing it. I no longer use them, so I'd be happy if someone else could. Below are the sizes of each part. Please use them as a reference. ・Lens width (horizontal): Approximately 5.5cm ・Lens width (vertical): Approximately 3.1cm ・Bridge width (nose width): Approximately 1.5cm ・Frame width: Approximately 12.5cm ・Temple length: Approximately 14cm P.S. Although not a dedicated case, I'll include a glasses case as a bonus.
