266 pcs Optical Trial Lens Set Kit Metal Rim Aluminum Case

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.

Very useful trial lens set. Other reviews say the lenses fell out of the frames included. I do not have this issue. The included frames hold the lenses very well.

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.

The lenses themselves are great. The accuracy appears to be very good, and they include a wide range of power options and other tools. The trial frames that come with the kit are not good quality though; there is no PD adjustment, and setting the correct cylinder lens axis is extremely difficult and sometimes impossible. I would get a second, higher quality set of trial frames, which these lenses work with.

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.
