Customer Reviews
I like the design of these glasses a lot, and I have bought multiple pairs over the years. However, this company has treated me as a regular customer absolutely horribly.
I originally found this design sold on Amazon, where they are sold at a lower price but without lens customization options; hence, my decision was to purchase one rather expensive pair with the anti-glare of the website for well over double the price. However, whilst they are very pretty, they are also very delicate, so thereafter, I stuck to Amazon.
Eventually, I had an arm snap off a pair within a week of purchase from the hinge getting caught in the case, so this time, I decided to make use of the lifetime warranty card each pair came with and contact support. I was very swiftly offered a 50% off coupon which I thought was very fair, and went to use it, however it could only be used on the Cyxus website and with the coupon the glasses still wound up well over the price listed on Amazon, which is where I had bought this previous pair. Upon pointing this out, I was told by Cyxus support by email, not to worry, I will get a special surprise with my order as compensation. I naively took the risk, in good faith of the company and placed my order. What I received was another identical pair of glasses for well over what I would have paid just buying another pair off of their Amazon listing, and, guess what, the fantastic surprise... of absolutely nothing extra.
Completely mugged off and scammed. I just left it there but am finally bothering to go around and leave the reviews of my experience after seeing they have removed this Bursna colour option from Amazon entirely now, leaving me with no choice but to buy off the site for almost 4 times the price, or take my business elsewhere, which I will be doing from now on. Absolutely outrageous treatment of a loyal and regular customer. They may sell eye care, but they clearly lack customer care.

How to Read Your Prescription
1.What does my prescription (Rx) mean
‘+’ or ‘-‘
‘+’ – Shows if you are long sighted (longsightedness)
‘-‘ – Shows if you are short sighted (shortsightedness)
If your Sphere (SPH) is ‘+’,you are farsighted,please tell us that after you put on the glasses, do you see further clearly or see near clearly compared with not wearing glasses.
Each row of an Rx has three main sections: Sphere (SPH), Cylinder (CYL), and AXIS. The SPH section corrects nearsighted or farsighted vision. The CYL and AXIS sections correct an astigmatism.
There may also be a fourth section on the Rx , NV-ADD (for Near Vision-Reading ADDition), which could be used to order a pair of bifocal or progressive glasses with a close-up vision section in the bottom part of the lens.
The SPH, CYL, and NV-ADD numbers will always have a plus or minus sign.
How to Measure Your PD
PD stands for Pupillary Distance, which is the measurement from the center of one pupil to the center of the other. Your PD is an important factor and tells you where you look through the lens of your glasses and should be as accurate as possible. For people with strong prescription, this is especially important. You can normally find your PD on your prescription. Generally speaking, the PD numbers for adults stays the same. The average PD range for adults is 57-72 mm and for kids is about 43-58 mm.
Your pupillary distance (PD) is the measurement of the distance between your pupils.
This is needed for the manufacturer of the eyeglasses to know where to place the optical center on each lens, so you can see well with the glasses.
