# [Preventive Protection Against Blue Light](https://blog.blackwoods.com.au/uvex-blue-light)

Changing light conditions including bright light, reflective surfaces and variable outdoor light conditions in our daily working life can all put additional stress on the human eyes. The uvex CBR65 and CBR75 light transmissions improves contrast enhancement, reduces blue light and supports relaxed vision.

What is Blue Light?

In the electromagnetic spectrum, blue light lies in the wavelength range between 380 and 500 nanometres. It therefore falls within the visible part of the spectrum, to which we are exposed every day.

Blue light can be found everywhere – in the natural light emitted by the sun, or in the artificial light emitted by LED lamps or screens (smartphones, tablets, computers, televisions).

### Risks of Blue Light Exposure

- Eye fatigue
- Sleep rhythm disorder
- Age-related macular degeneration (AMD)
- Lowered Concentration

## uvex CBR

### Contrast enhancement

 **Ideal for accurate vision in every situation**

Bright light, reflective surfaces or using digital devices, changing light conditions can all put additional strain on the eyes which can be uncomfortable and increase the onset of fatigue.

The innovative uvex CBR65 and uvex CBR75 light transmission helps the eyes to focus more easily by providing better contrasts. This enables you to remain focused on the task at hand whether working in mining, construction, utilities; or on the golf course.

### B = Blue light reduction

 **Ideal for display screen equipment**

LED lights, computers and other visual display screens produce harsh, unnatural light with high blue light content that can over time, fatigue the eyes and may encourage headaches. 

The uvex CBR65 tinted lens reduces blue light by up to 50 % at 450 nm and the uvex CBR75 tinted lens reduces blue light by up to 40% at 450 nm offering protection against these harmful emissions. 

### R = Relaxed vision

Ideal for precision work

From harsh industrial to inspection work, there are many more tasks that require continuous levels of high concentration. The uvex CBR65 and uvex CBR75 lens technology delivers a relaxed field of vision, reducing the eyes from becoming fatigued. <https://www.blackwoods.com.au/uvex/b/557610/brand>
