How We Can Help Your Company

Our mission at Crossbow Visual Stress Solutions is to raise awareness of Visual Stress within the workplace and help 1000’s of people read and work at a computer with more comfort and better productivity. Visual Stress effects 1 in 5 people and can be the cause of headaches, migraines and time off work (click here to found out more about Visual Stress).

Crossbow Education: The Visual Stress Collection won SEN Product of the Year at the Educational Resources Awards in 2014 and provides resources to 70% of schools in the UK. We work along side and use the research of Professor Arnold Wilkins (from Essex University, the leading researcher on Visual Stress in the UK) for the basis of our products.

Visual Stress is relatively new research, meaning there are many people within the workplace who are suffering with Visual Stress unknowingly and think the symptoms they have are just the norm. Helping people with Visual Stress in the workplace is simple, affordable and can make a huge difference to work life and home life.

We aim to do this with our expert knowledge and our Visual Stress Collection.

The Visual Stress Collection:

Monitor Overlays:

19inch_all3.jpgSome of the biggest complaints about working on a computer screen all day are headaches and sore and tired eyes. Our monitor overlays reduce the glare from white background and the glare from the monitor screen which is a cause for these symptoms, meaning they help with Visual Stress and Computer Vision Syndrome (please click here to find our more).

Our Monitor Overlays come in different sizes to fit all monitor screens. They are simple to use – they just lie flat against your monitor screen, using static electricity to stick. Available in 5 colours: Yellow, Green, Aqua, Sky, Pink.

One of our assessors can come to your offices and assess your staff for Visual Stress and provide them with the correct resources afterwards. Our assessment takes around 20-30 minutes per person using our Visual Stress Assessment Pack (please see below). Once the assessment is completed the assessee will have gained awareness of what visual stress is and how to make reasonable adjustments for visual stress e.g. monitor overlays, tinted paper, lighting and sitting position and what their optimum colour is.

Assessment are available at £40 per person, with discounts for larger groups.
