Product Information

House Windows

If you are extremely light sensitive, perhaps one of the first steps you need to take is to screen out the harmful light that enters the windows of your home. Even to screen a few of the most useful windows makes you feel more part of the world.

DermaGard is a transparent window film applied to the inside of your window that screens out more than 99% of UV and is virtually unnoticeable.

Fluorescent Tube Filters
It is possible to purchase sheaths that are very easy to fit over fluorescent tube lights to screen out UV; this film tube is easy to cut, to shorten or to overlap to extend length. See Bonwyke above. It is the duty of the employer to provide these for light-sensitive employees who have to work under fluorescent lights.

UV Photo-protective window film

Museum Film 200 (UV Dermagard)
The following chart shows that although this film provides a total block of UV rays up to 380 nm, the level of light transmission steadily increases with the longer wavelengths of visible light. It is important to note that almost 80% of visible light at 500 nm is being transmitted through Dermagard. (Manufactured by Sun Guard, Florida, USA)

It is often assumed that protection against UV wavelengths (up to 380nm) will keep you safe. However some people are harmed by the blue spectrum of visible light (beyond 400nm). It is necessary to undergo light testing at a specialist light sensitivity unit to find out which wavelengths are harmful to you.

(Details of these later.)

If you need protection beyond UV, there are window films offering further protection, which can be found in the Bonwyke catalogue, though these may result in colour distortion or a very dim interior.

Blinds
A simple way to add extra protection is to add blinds to pull down when the windows are not in deep shade.

If your local blind company cannot provide what you want either in blackout or anti-glare blinds contact the British Blind and Shutter Association (BBSA) and they will put you in touch with a range of companies who will:

Car Windows
It is equally necessary to screen car windows against UV with something like DermaGard. It is necessary to have your car screened by an expert technician and it is not permissible to apply yellow film to car windows as this is against safety rules. It is illegal to apply darkened film to the windscreen but it is allowable to darken front side windows to an extent. Rear side windows and the rear window may be darkened to the full extent.

Car Window Film and Visible Light Transmission (VLT)
If you have to have your vehicle fitted with window film due to light sensitivity, we have established from the Deputy Prime Minister's Office that there are no dispensations due to medical grounds. The windscreen must allow at least 75% of light to be transmitted through and the front side windows 70% VLT otherwise you are committing an offence. Anywhere behind the driver's seat (rear windows) can be as dark as you like! There is, however, a recognised difference between "light window tints" which may be considered safe for road use and "excessively dark window tints" which are not.

Passenger Sunshade
These precautions may still be insufficient to protect you from sun shining into the car window and in such circumstances you may need to cover yourself (face included) and travel as a passenger.

For fuller advice see "Travelling Safely" in "Practical Aids".

Personal Covering

A person with severe light sensitivity should use a high factor sunscreen (SPF 50 or above) outdoors during all seasons, even on an overcast day. It is equally necessary to wear sunscreen indoors under energy saving lights, which emit high levels of UV and the blue spectrum of visible light. Some sunscreens can be obtained on prescription eg. Uvistat and Sunsense Ultra - ask you doctor about this. Eyes should be protected with prescription glasses, sunglasses or wraparound overglasses that screen out UV. More information about Choosing and Using Sunscreen can be found in the 'Information and Advice' section

Some people may find sunscreen is insufficient and need fabric face shields. These are available from suppliers of sun-protective clothing, notably:

Sunsibility in the UK
web: www.sunsibility.co.uk

Sunprecautions in the USA
web: www.sunprecautions.com

Under "Practical Aids" there are instructions on making a transparent visor which will screen out UV.

Face Shields and Masks

Ski Masks or Balaclavas - for some of us sunscreen is not sufficient and we need more solid face shields. In winter you can get away with ski masks or balaclavas from sports outlets. These are especially useful if it is windy.

Face Shields and Head Wraps - in warmer weather it is possible to use a face shield obtainable from Sunsibility in the UK or the Sun Precautions Company in the USA. Details below

You can view/order items available on www.sunprecautions.com

You can make your own head wraps and face shields by using sun-protective fabric.

Computers and Televisions

Anti-radiation Filters
Can be fitted to your computer and television screen. (It may require extra securing with blu-tack and tape if TV is curved). These filters reduce, but do not eliminate the problem of light exposure, so still keep as far away from them as possible. Some also eliminate E-field radiation. The cheapest we have found are available from Viking Direct

Electrical Hypersensitivity
Some light sensitive patients have been aware of a hypersensitivity to electrical radiation. One member has recommended the following book on the subject:

The Powerwatch Handbook by Alasdair and Jean Philips
Pub: Piatkus Books Ltd.
ISBN 0 7499 2686 4

This is an informative and easy to read guide with lots of practical advice.
