SETO 1.59 PC Progessive Lens HMC/SHMC

PC lens, also known as "space film", because of its excellent impact resistance, it also has a commonly known as bullet-proof glass. Polycarbonate lenses are highly resistant to impact, won’t shatter. They are 10 times stronger than glass or standard plastic, making them ideal for children, safety lenses, and outdoor activity. Progressive lenses, sometimes called "no-line bifocals," eliminate the visible lines of traditional bifocals and trifocals and hide the fact that you need reading glasses.

With three prescriptions in one, there is no need to change glasses constantly. It’s one pair of glasses for everything. No distracting and distinct bifocal line The drastic difference between prescriptions in bifocal lenses is often distracting and even dangerous if you are using them while driving. However, progressive lenses offer a seamless transition between prescriptions allowing them to be used in a much more natural manner. If you have already owned a pair of bifocals and found the sharp difference in prescription types distracting, then progressive lenses may hold your solution. A modern and youthful lens You may be slightly self-conscious about wearing bifocal lenses due to their associations with old age, especially if you are younger. However, progressive lenses look just like single vision lens glasses and don’t come if the same stereotypes that are associated with bifocals. Since they don’t have a big difference between prescriptions, the bifocal line is invisible to others. So they don’t come with any of the troubling stereotypes associated with bifocal glasses.3.
