It takes about ten minutes to read this article and you will get to know how much attention to detail Oudopanda puts into its products. All our colored passive glass is 100% tested in three processes. We guarantee that the shade control of each glass is no more than ±0.2. Oudopanda offers 1 year warranty on every lens and produces the best quality, richest colors and clearest weld view of colored passive glass in its price range.
Welcome to the world of Oudopanda - Colored passive glass. Let me introduce you what makes it different.
(1). Waterproof
Between the individual layers of glass, we apply 3M adhesive to the edge using a professional dispensing machine. At the same time, the adhesive is dried in our UV curing machine and finally firmly bonded together using an ultrasonic device. You will hardly find any traces of glue on the edges or in the middle of the glass. This is because our machine can strictly control the amount of adhesive and at the same time precisely control the position of the adhesive on the glass.
This allows Oudopanda passive glass to be 100% waterproof in most cases. The edges of the glass are sealed with a special material that largely reduces the possibility that the interior will be damaged by water or moisture.
(2). Heat resistance
The raw materials of glass consist mainly of quartz sand, sodium carbonate and limestone, some of which are extracted from the ground or from salt lakes.
In order to achieve better heat resistance, we make our exclusive mixing ratios and feed these mixed materials into the furnace, where they are heated to 1600 degrees Celsius to melt and form the glass liquid, which is then pressed to form the 2x4.25 inch glass. Due to the strict control of each individual process, the heat resistance is outstanding. Thanks for the superior heat resistance, it can work normally at high temperatures of up to 300 degrees.
(3). Strong impact resistance
After the glass is molded, it is cooled to free it from the high temperature and gradually cool it down to room temperature. In the process, we fight for several seconds between two pieces of glass plus 3M adhesive and then UV thermalization to make the seal even stronger. At a later stage, we cut, grind and polish the glass to ensure that every piece of passive glass you receive has excellent flatness, good surface finish and aesthetic degree. It is precisely because Oudopanda pays attention to these details that it is particularly impact-resistant.
(4). Newly upgraded grinding process
Oudopanda's colorful passive glass has an advanced edge grinding that makes it very easy and comfortable to pick up, use and put down. You can feel the silky feel of the lens without having to worry about being scratched by the sharp edges. This design makes the lenses not only more fashion, but also more impact resistant than ordinary passive glass.
(5). Better optical quality, preferred optical class 1/1/1/1
During the welding process, ultraviolet (UV) and infrared (IR) rays are generated which are harmful to the eyes. These rays are invisible to the human eye, but if they are not properly protected, they can cause serious eye injuries or, worse still, blindness. Welding safety glasses are based on optical glass and use colorants such as iron oxide, cobalt oxide and chromium oxide. In addition, a certain amount of cerium oxide is added, which can block 99.9% of red UV/IR rays.
OPTICAL CLASS (ACCURACY OF VISION) 3/X/X/X
Do you know how distorted something can look through water? That's exactly what this class is about. It rates the degree of distortion when looking through the welding helmet lens, with 3 meaning you see as if through rippled water, and 1 meaning there is virtually no distortion - practically perfect.
DIFFUSION OF LIGHT CLASS X/3/X/X
When you spend hours looking through a lens, the smallest scratch or chip can have a big effect. This class rates the lens according to manufacturing defects. 1 means that it is free of impurities and exceptionally clear.
VARIATIONS IN THE LIGHT TRANSMISSION CLASS (LIGHT OR DARK AREAS WITHIN THE LENS)X/X/3/X
Oudopanda passive lens shade offer #9; #10, #11, #12. This class rates the consistency of shade across different points of the lens. Basically, you want the tint to have a consistent level from top to bottom and left to right. A level 1 will provide an even shade throughout the entire lens, while a 2 or 3 will have variations in different areas of the lens, possibly making some areas too bright or too dark.
ANGLE DEPENDENCE ON LUMINOUS TRANSMITTANCE CLASSX/X/X/3
This class rates the ability of the lens to provide a consistent level of shade when viewed from a specific angle. (This is because welders have to weld at different angles in different work situations, e.g. pipe welding, backside welding, etc). This assessment is therefore particularly important for anyone welding in hard-to-reach places. It checks whether the view is clear, without stretching, dark areas, blurring or problems when viewing objects at a certain angle. A rating of 1 means that the shade stays consistent no matter the viewing angle.
(6). Precise control of shade number within ±0.2
All Oudopanda brand passive glass raw materials are triple tested manually + with a European machine + with self-developed instruments to ensure that the shade number of the passive glass in your hands is precisely within the ±0.2 variation range. (When testing most other passive glasses on the market and even the auto-darkening welding lens, we were surprised that the shade number of most products is much more than ±1, which means, it is advertised as shade 9, but in reality it is between 10 and 11!) ). When selecting the raw materials, 20% of the passive glass has already been sorted out, which is an amazing figure!
(7). Minor errors in the control spectrum
Each Oudopanda passive glass has its own fixed spectrum. We are also equipped with professional spectral testing equipment and have developed our own software, together with strict screening by our staff, ensures that every piece of our colored passive glass has stable performance, excellent quality and low color difference error.
Dear welder friend, I am glad you stopped by. Although we want to make our products as perfect as possible, but probably there are still details that have not been taken into account. We would be delighted if you could make suggestions with us to make the product the way you want it.
What additional functions would you like to see in our product? Write us a comment in the comments section below.
For those who make suggestions, we will select one person to give away 1 piece of colored passive glass and 5 pieces of branded stickers. We look forward to your feedback and suggestions----From Oudopanda Team

How about a crimson, purple, gold lense

Hello, is it possible to buy two blue glasses? How can I do it?
Alex
I would like to see a yellow or amber colored lens. I have a polycarbonate amber colored lens and really like the color but the detail and clarity is way below any glass lens
Luke Croukamp
Awesome information. Really informative. glad to see these lenses have great heat resistance as some old time welders reckon that multiple glass layers peel over time and are prone to cracking especially with high heat.
So much research and development and excellent sounding products need better photos for social media and your website!
Also I would love too see a yellow coloured welding lens.

I’m really impressed with the information provided on these lenses. Coming from the US there aren’t many vendors that will put in the effort to help their buyers understand the product they are buying. Also it would be cool to see some zipper cases for the lens like tefuawe.
