1. Progressive multifocal lenses: Progressive multifocal lenses are suitable for various daily needs (such as everyday conversations, computer use, and reading), eliminating the need for frequent use of reading glasses. The standard pupil distance and precise magnification ensure comfortable wear without dizziness, effectively enhancing reading convenience. 2. Antiblue light glasses: These glasses block 99% of harmful blue light, protecting your eyes from exposure to computers, ereaders, TVs, gaming devices, and tablets. They reduce eye strain and headaches, allowing you to enjoy reading and screen time without worrying about fatigue, blurred vision, or headaches, providing allday protection. 3. Reading glasses design: The frameless reading glasses do not obstruct your line of sight. They feature a modern, comfortable rimless frame with flexible hinges, quality silicone nose pads, and adjustable temples. The rimless multifocal reading glasses are designed with three visual zones. 4. These progressive multifocal lenses are divided into three zones: upper, middle, and lower. The upper zone has no diopter (0 diopter). The middle zone serves as a transition from 0 diopter to your selected strength (e.g., if you choose 1.0 diopter, the middle zone will be 0.5 diopter). The lower zone provides the full reading strength you selected.
