Excessive glare is a common cause of reading problems and eyestrain.

Glare refers to unwanted light that is reflected from the image that we are looking at.  For example when we are reading black print on a white page the light reflected off the page into our eyes is called glare.  Glare scatters light inside our eyes and causes eyestrain.  This also reduces visibility and makes it harder for us to focus.  Eyestrain is not only stressful and uncomfortable, but it also causes difficulty in making efficient saccade eye movements.  Saccadic eye movements are the important eye movements we use when we read.

We recommend using a blue filter light system, which has two benefits:

• Firstly the blue filter reduces the size of the eye's pupil (the pupil is the black "window" that lets light enter the eye).  A smaller pupil will reduce glare entering the eye.  A smaller pupil also makes it much easier to focus when we are looking at print close up.
• Secondly the blue filter light increases visibility of the print, while not reflecting light off the page.  The glare is therefore reduced, while the visibility is improved.

An efficient focus system with good visibility will make the eye movements in reading easier and reduce fatigue.

Our Blue Filter Lamp Pack comprises a lamp with blue filter bulb, a ballpoint pen with the optimum nib width and a ream of coloured A4 paper.

We hope you enjoy using your blue filter lamp.
