Review on 👓 Progressive Multifocus Reading Glasses with AR Coated Lenses Medium Fit Unisex by Sightline's: Premium Quality Acetate Frame by Jaxon Prince

These are progressive trifocals, glasses with three different focal lengths (ie three different dioptres) with no lines between the lens parts. I tried these prescription drugs once and didn't like them, but these turned out to be good. I wear them a lot, every day for ten days. I mainly use the middle part of the lenses. It's big enough that they work like my regular readers most of the time and I don't notice any difference. To use other diopters I have to nod or raise my head to change the angle; it doesn't happen by accident. That's good, but means those parts of the lens might not be as comfortable to use depending on the direction you're looking. All three diopters work as intended and they look accurately marked. The optical quality seems to be good. The spring-loaded temples work well and hold the glasses in place no matter how I turn my head. These frames are designed for medium-sized heads. It's 53-18-140, meaning the lenses are 53mm in diameter, the parts that sit on the nose are 18mm apart and the temples are 140mm long. These numbers are often printed on the inside of one of the levers if you want to compare them to your current frames. This manufacturer also sells these lenses in other frames in different sizes. They come with a cloth pouch in different colors (see one of the Revain photos at the top left of the product homepage). Sightline is an American company. The glasses are made in Vietnam. How to Order How many diopters you need to order depends on how you intend to use them. Diopter order numbers refer to the underside of the lens. If you plan to use them primarily for reading something like a book, use the bottom of the lenses most of the time (because of the angle between you and the book). , you need to order the diopter number you usually use for it. This usually works for other purposes as well, but if you plan to use them mainly to read from a computer monitor, for example, which is more even with your eyes, you can order a center section. I mainly use Reader for this. I usually use 1.00 for this, so I ordered 1.50 which has 1.00 in the middle. Here are the three diopters for each order option, starting from the bottom of the lens, this is the order number: 1.00, 0.75, 0.301.50, 1.00, 0.502.00, 1.50, 0.752.50, 2 .00, 1,253.00, 2.50, 1.50 If you've never used reading glasses or don't know what diopter you have (check the temples on your reading glasses you already have), most pharmacies, large grocery stores, stock Wal -Mart shopping malls etc. Reading glasses where they can be tried on. You need to find the ones that work best for the distance you intend to use them at. The lower the diopter, the farther away the field of focus.
