Adlens Adjustable Eyewear-Instant 20 20 Vision-Non Prescription Lenses -Both Nearsighted & Farsighted Variable Focus Glasses-Computer Reading Driving Eyeglasses-Men & Women – Centurion Optical

These eyeglasses are stylish and versatile. The "adjustment mechanism" is easy to use making for the greatest clarity and good vision.

I purchased these as a gift for a friend in Costa Rica. Today, I gave them to him and they were of NO benefit. They were more expensive than many other models, so I purchased them. Very poor quality and basically junk. I would recommend NOT buying them!

They do work, to some degree, with my amblyopia, and they may well work well for you. Past that they are a far cry from a visit to your optometrist.

These glasses are so cool! I absolutely love the way you can turn the little knobs on the sides and focus them just the way you need them! They are great for sitting at the computer when my regular glasses are too strong.

Better than I expected. The frame wasn't straight and I had to fiddle with the left knob to get it to adjust the lens when turning. There is some noticeable light reflections but it is not really distracting. You should make sure the glasses are adjusted everyday because the adjustments do shift by themselves. Wear them close to reduce any distortion and the rubber grips prevents them from sliding down. When looking through them, it's most effective when you look straight at your object. Compared to prescribed lens, it has some ways to go, but it's adjustable and it works quite well. With improvements, these glasses could be a household product for people with myopia/presbyopia.

Was excited to buy these. My eyes are different. So reading glasses don't quite relieve the screen strain. Very clever idea, there are two overlapping lens for each eye. The adjustment knob changes the overlap. You can indeed dial in each eye similar to binoculars.However the lens are plastic and the optics are not clear even when focused. I use 1.25 strength reading glasses. For me they ran out of the adjustment range while I was close to the lap top comfort zone. So they will be ok for occasional close work. But not for working at the computer.Looking forward to a higher quality version.

Highly adjustable and great in a pinch. Will not replace a properly fitted prescription pair of glasses. Does have a great range to help your vision. No correction for astigmatism.

Look at the other critical reviews, they are all completely correct. Plastic lenses do not focus well and have glare, very uncomfortable plastic frames hurt your nose and temples. Item arrived was obviously used/returned-imagine that.
