This trial lens set has already paid for itself. I took my original prescription from three years ago and loaded up the corresponding lenses into the lens frame and then did some minor modifications for my distance and close-up and got considerable improvement. Then went on the Internet and entered my new prescription and got bifocals at quite a discount compared to what you would receive going to a optician. I am not saying that this set is for everybody. But if you are technically inclined and can accurately interpret a previous prescription, it is fairly easy to do. Of course everyone is different. I took a chance and bought this set. It turned out to be a very good investment. I've never been a big fan of phoroptors. Every eye exam I have had with those machines has been for the most part a very hurried experience. With this lens set, you can take your sweet time, experiment with the different lenses and feel really satisfied with the result. I am impressed with the variety of different powers of lenses as well as the astigmatic lenses. The lens frame itself could be a little bit more sturdy, but I found it adequate. You can load up as many as three lenses for each eye if you wish and also have the ability to rotate to get your degrees for your astigmatic lenses. Of course this does not replace medical eye exams that check for such things as cataract, glaucoma, and macular degeneration. But it certainly does give you a a lot more control when it comes to getting new bifocals. Read more

The quality of the lens are good. The trial frame is a joke, so get a separate, good one. The lens do need cleaning, and a few had a couple of dings, but for the most part, the set is whole. Takes a bit of effort to learn how to use a trial lens set, but once you do, it's a good way to double-check a prescription. Read more

Inner casing is essential to keep lenses in place. Sadly this arrived with the inner casing broken and with cracks . Not sure how long it will last before it completely falls apart. I asked for the casing to be replaced but sadly that is not an option. Hopefully the seller will see the need to replace what is damaged to me. Read more

I am happy so far—although there were a few lenses with scuffs, and one with a deep scratch. As someone else mentioned, you will have to clean all of the lenses before use, as there seems to be a small amount of machine oil smell and coating on the lenses. It took about an hour to clean up. All is good now. I do not have a lensometer, so I cannot attest to the accuracy of the lens, but I will find out when my online glasses arrive. I am excited about this since I can verify or augment my prescription for many different working or playing situations. If you are a beginner like me, there are plenty of online videos—the review failed review last time since I posted a link, so I won’t do it. Except to say, there is a guy that is doing prescriptions in Africa and making several videos on every step on the how and what. Find it and learn. Read more

High quality kit as far as I can see. I found no scuffs, and the small increments mean you're less likely to need to add together two lenses, which can be a pain especially for astigmatism. Look somewhere else for the frame. No way to adjust the nose bridge, the PD fixed at 62, likewise for vertex distance and tilt. I was most bothered by how the labeled axis angles on one side do not match the labels 180 degrees on the other side (plus or minus 10 degrees), I might as well use a separate protractor... These aren't problems for smaller prescriptions, but it's something to consider. Read more

These are sold as eye testing equipment. The pupil location crosses are unusable, the Jackson cross cylinder lenses' markings suggest the meridian is off to the side somewhere, and the off meridian isn't at 90 degrees to it. The cylinder lens markings waver all over the place. Who knows what the power and centre of the spherical lenses is. This is not OK. Read more

Product arrived with no damage in immaculate condition. Slight machine oil smell as to be expected. I ordered this after 4 separate eye doctors tested me in under 2 min. Each time I explained that the images were not at all clear with severe ghosting and that I have an astigmatism and to please check again. They told me to get my new glasses and come back next year. 5 years of distorted images and headaches to realize the optometrists were simply lazy and never even did the basics of optometry. I solved my astigmatism problem in a couple YouTube videos and an hour with this product, finally resolving 5 years of frustration. If you are in a similar boat as me this product is amazing at this price. Read more
