Tinted optical wear include glasses or contact lenses that have a coloured tint specifically designed to improve sight or viewing for the wearer. Tinted optical wear can be used to reduce the effect of light sensitivity, assist with the transition between different light levels and treat certain eye related pathologies. Some coloured or tinted glasses are also being recommended for certain learning disabilities such as Dyslexia. Tints can be graduated over a lens or cover the whole lens, and can be purely for fashion purposes or prescribed for a particular purpose.
Another type of tinted optical wear is that of transition lenses where the lens changes tint depending on the level of light exposed to. Therefore the lenses are light when inside and go dark when moving into sunlight.
Workplace solutions and adjustments:
For people reporting eye fatigue, soreness or headaches within the workplace, overall workplace/workstation set up to review lighting and glare should be considered. If no improvement is noted, an assessment of an individual’s vision may be recommended which could result in the prescription of appropriate optical wear if any eye related or visual perceptual conditions are noted (DiFranco 2000-2008; The Eyecare Trust 2003; The Irlen Dyslexia Centre).
