What does CR Surfacing mean?
CR comes from the technical term CR-39, the special material that the first plastic optical lenses were made of in 1947,a much safer and lighter alternative to glass lenses. CR Surfacing was the first independent optical laboratory in Australia, that supplied plastic optical lenses, in an era when people were glass lenses in their spectacles. We take pride in the company’s innovative core as we maintain our investments in cutting-edge equipment and the latest technologies.

Can I order my lenses directly from you?
No. As a wholesaler, we do not supply our lenses directly to the public. Our lens descriptions do not replace the eye test and personalised dispensing that is vital to customise the lens solution for your eye condition and visual needs. Our high-quality products require professional eye examination and dispensing to provide unparalleled visual performance.
What is blue light? How does it affect my vision and what can I do protect my eyes?
Approximately one third of all visible light is blue light, a high-energy light that has a number of biological effects, including on the eye. Blue light penetrates all the way to the retina and can damage the light-sensitive cells and can increase the risk of age-related macular degeneration. Although not all blue light is bad, as it helps boost alertness, memory and cognitive function, the harmful wavelengths can be filtered out with Satin Blue coating, providing maximum comfort and protection for your eyes.

What are computer glasses?
The expression “computer glasses” is used for a range of products. There are specific lens designs developed to maximize visual performance for digital devices and office environments. These Office Lens designs are often referred to as computer glasses. People also recognise blue filter lenses as computer glasses, since this special lens coating is developed to protect the eyes from harmful blue light coming from digital surfaces.
What is digital eye strain?
Digital Eyestrain, also known as Computer Vision Syndrome, is a condition that occurs when using digital devices for extended periods of time, resulting in blurred vision, red, tired and dry eyes, developing headaches. These symptoms are caused by a number of factors related to the usage of digital devices. The constant re-focusing to objects in different distances, and the excessive exposure to artificial blue light has a toll on our eyes.
CR Surfacing’s Office Lenses support the ciliary muscles and prevent symptoms of fatigue, offering enhanced visual comfort and relaxed, clear vision to the wearer.
These lenses are recommended with Satin Blue anti-reflective coating, a blue light filter to reduce digital strain and help protect the eye. CR Surfacing’s special glare-reducing Satin Blue coating filters out harmful blue light coming from digital surfaces, as well as natural and artificial lights.
What are the benefits of anti-reflective coatings?
Across the surface of the lens, 4% – 9% of light is lost by reflection. Anti-reflective coatings work by interfering with light reflected off the surfaces of the lens and ‘cancelling out’ reflected light. This means that more light is transmitted through the lens and less is lost in reflection, making the wearers vision clearer.
Anti-reflective coatings are particularly useful for glare-sensitive people and those who are concerned about the cosmetic appearance of their lenses, as they reduce the reflections off the lens surfaces, making your eyes visible and more enhanced – especially for those everyday essential selfies.
