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. It is the duty of the employer to provide these for light-sensitive employees who have to work under fluorescent lights.

The following are suggestions to help people affected by UV and blue spectrum light to choose the most appropriate LED lightbulbs. Sadly, some have reported adverse reactions to all LEDs, irrespective of colour temperature, so this advice will not apply to them (except perhaps as being 'the lesser of the evils').

The current regulations for energy efficiency will soon result in only LEDs being available on the market.

Best Option:
1. Choose LED lightbulbs with a colour temperature of 2700k.
(Special "Heritage" bulbs are available at some stores with an even warmer colour temperature.)

2. These LED light bulbs are usually called Warm White and have a lower output of the blue light spectrum. (Avoid Cool White and 'superbright' which have higher blue emissions).
(Be careful - the lower the kelvin number, the warmer and less blue; the higher the kelvin number the cooler and more blue.)

3. If possible choose a filament design. This will generally be stated on the packaging. (Usually a filament LED is comprised only of a glass bulb with a brass lamp holder so avoid plastic based lamps or those with a plastic segment between the glass bulb and metal base).

- Although filament bulbs usually emit warmer light, you may find cold looking filament LEDs that are worse than some non-filament LEDs

- Cheap LED bulbs of all types are prone to flicker

- This is still a difficult market with insufficient product information so you will need to trial what you buy to find something tolerable for you.

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)

Wavelengths (nm)

Transmission (%)














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.

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.

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

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.

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

Sunprecautions in the USA
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

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

De-mister for Dermagard Mask
Prevent or lessen the misting up of your Dermagard mask by using household washing-up liquid or a product especially for this purpose such as: Salclear D-Mist+

Facekini face mask for Sun Protection - This simple, relatively unstructured headgear is made from a smooth nylon/lycra blend (SPF 50) and covers entire head and neck with holes for eyes, nostrils and mouth. A member bought a couple to protect herself during dental treatment. These could be equally useful for treatment for eyes and nose.

Facekinis are made in the USA but can be bought on-line for £7.64 plus postage which is minimal as they are very light. They can be pruchased on Etsy. These somewhat ghoulish-looking garments are all the rage in China where umpteen numbers of people can be seen sporting them on beaches and in the sunshine. It strikes me as quite ironic that in China, healthy people are wearing these masks without a qualm, while here light sensitive patients wearing medical masks are semi-criminalised. We really need to promote our plight as widely as possible.

Being outside is good for both physical and mental health but when going outdoors it’s important to protect your skin from the sun (even on cloudy days).

ALTRUIST was initiated by Dr Andrew Birnie, a Consultant Dermatologist and skin cancer surgeon based in Canterbury. In partnership with some of the best formulation scientists in Europe ALTRUIST provides premium, affordable sunscreen through reducing profit margins and unnecessary marketing costs. This high-quality, ethical, environmentally friendly and affordable sunscreen range is available from Altruist direct and other online sources including Amazon.

Smartphones, Computers and Televisions

Technology has changed rapidly over the past few years, with modern screens having far less electromagnetic radiation but brighter light.

This can be detrimental to those with moderate to severe light sensitivity, making everyday tasks like typing a text message or using the computer difficult.


BlueShields by LowBlueLightsis a line of one-of-a-kind 100% blue-blocking filter designed to be fitted over smartphones, tablets, computers and TV screens to eliminate blue light which other filters on the market cannot provide.

The LowBlueLights filters can be applied and removed without using any adhesive or leaving a residue on a device’s screen. Also, the filters are approximately 14mil thick allowing for full touchscreen capability.

Non-Filter Methods

Depending on your degree and type of sensitivity, one, or any combination of the following may be worth trying:
• Dimming your device’s monitor/screen.
• Adjusting the colour, reducing the blue.
• Extending the keyboard and mouse cables, so as to be able to sit further away.
• Wearing light-proof masks and clothing and dark glasses.

These non-filter methods can be ideal for when watching TV (with a big enough screen). However, they may not work with computer screens because although you can increase the size of the font to be seen at a distance, you cannot necessarily increase the size of a toolbar or some online content.

As reflected light is better than direct light, and a large enough screen makes even computing from 5 metres quite possible, some use a projector to do all their computer work, watching of TV and films. You can get a portable stand-alone TV/DVD projection machine. However, these do need to be aimed centrally at the wall/screen (taking up a lot of space) and may not be suitable for computing. More expensive projectors can be ceiling-mounted and can be used for everything you would otherwise use a television or computer screen for but can cost a lot of money and tie you to one space for everything - certainly not as convenient as a tablet! If you wish to try this, contact a local computer dealer who also deals in projectors/multimedia.

Sony has brought out an e-ink tablet. We hope these will eventually be a marvellous computing device for the light sensitive. As yet however they are hugely expensive and only available in the USA and China.
