Q&A

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 wore 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.

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. Find your nearest optometrist here.

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 True Blue coating, providing maximum comfort and protection for your eyes.

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.

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 True Blue Coating, a blue light filter to reduce digital strain and help protect the eye. CR Surfacing’s special glare-reducing True Blue coating filters out harmful blue light coming from digital surfaces, as well as natural and artificial lights.

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.

Shaw Lenses are specialty products for specific eye conditions (such as amblyopia and aniseikonia), that only qualified optometrists can prescribe. These lenses can be used for any prescription; however, the optometrist will determine the best solution for your individual visual needs.

Avulux is a specialty lens designed to help individuals manage the impact of light sensitivity symptoms resulting from migraine and/or other neurologic and eye disorders. Unlike specialty tints, Avulux is the world’s first clinically proven lens for migraine and light sensitivity management. Auvlux lenses utilize a proprietary multi-band precision optical technology to selectively filter blue, amber, and red light while allowing through sufficient green light.

Unlike other “migraine glasses”, Avulux patented optical technology filters blue, amber, & red light, while letting soothing green light in. Avulux is the only light sensitivity lens to ever be proven effective through an independent, double-blind, randomized, placebo-controlled clinical trial.

Wear Avulux at the onset of any migraine or light sensitivity symptoms. Avulux can be worn continuously, or as needed. It is recommended you wear Avulux prior to light-triggered pain setting in and especially during any known trigger activities (screen time, while under harsh lighting, etc.). Avulux may be worn indoors or outdoors. If you have over 15 monthly headache days, or continuous light sensitivity, wear Avulux throughout your day.

Avulux lenses are not certified for driving due to their filtration properties (this has nothing to do with any vision correction properties).
