The science of sight Why does small print get harder to read in the evening?

Your eyes need more light as the years go by, and light that is short of the deep reds leaves print less distinct, however bright it is.

The amount of light matters, and so does what is in it.

At 60 your eyes need about three times the light they did at 20, which is why a lamp that was fine years ago may not be enough on your page now.

An ordinary LED is built on a blue chip and leaves the deep reds thin, so adding more of that light does not put back what is missing from it.

See what better light does for you

Contrast is what makes small print easy to read.

The deep reds are what make black type look black, and they are the part most LEDs leave thin.

Daylight Wavelength Technology™ puts them back: the HD Original scores 92 on the deep reds, where the ordinary LED we measured scores 40.

I am delighted with my light. Now I enjoy reading and writing again after a long time.

We have measured our light against daylight, and it scores 98 out of 100.

The specialist components in a single HD Original cost more to manufacture than many entire lamps sell for. That is where the price goes.

The HD Original and the HD Essential are hand-built in Aylesbury, and all three come with a five-year warranty and our team’s help with advice and repairs. Each one is made as a reliable tool for people who want the best light they can have.

Questions people ask about light and sight.

How much light do I need?

More as the years go by: at 60 your eyes need about three times the light they did at 20. Where the light falls matters too, so a focused beam on your page does more than a brighter room.

What is colour accuracy?

It is how faithfully a light shows colours compared with daylight, which scores 100. It is measured on the TM-30 standard, and Daylight Wavelength Technology™ scores 98, where the ordinary LED we measured scores 83.

Where can I read the research?

Our research page gathers the growing evidence on the wider effects of the kind of light you read by.

Read the research
What makes it different from an ordinary lamp?

An ordinary LED builds its white light around a strong blue peak and leaves the deep reds thin, which takes the contrast out of print and makes close shades hard to tell apart. Daylight Wavelength Technology™ starts from a purple LED and rebuilds the rest of the spectrum: it scores 98 out of 100 for colour accuracy, where the ordinary LED we measured scores 83.
