This product is reading glasses and is not multi-focal eyewear like progressive lenses. I am takufa, the seller and a user of these glasses. My eyesight is 1.0 or better in both eyes, but I have presbyopia from smartphones (around +1.5). I currently use this model, which ranges from +1.00 to +5.00. The frame width is a little wide, providing a comfortable fit. I feel that the blue light cut function makes the screen easier to see. The lenses are tinted gray, so they are a little darker than clear lenses. In bright places, the main body appears bluish, so it doesn't seem to be a complete gray. Regarding the automatic adjustment of the power, the lenses incorporate multiple different powers (+1.00 to +5.00), and the "easiest-to-see power" can be used depending on the user's degree of presbyopia. To put it simply, it's like reading glasses that can be shared even by people with different degrees of presbyopia. The easiest-to-see power is automatically adjusted according to the predetermined focal length and the user's degree of presbyopia. No adjustment of the reading glasses themselves is necessary, and of course, there are no dials or knobs. You just put them on. My feeling is that the eyes select the power that makes things easier to see within a distance of about 15-40cm. Regarding the automatic power adjustment, it feels like a fixed power in actual use, but it is well-received as being easy to use even for people with different powers than mine. I don't have any presbyopia sufferers exceeding +3.00 around me, so I haven't been able to confirm the usability of those powers. I think it's perfect for PC and smartphone work. Please use it in a well-lit room when reading. #Hazuki Loupe #Do Active #Pressby
