What is the best kind of reading light?
Qualified optometrist Simon Kay BSc(Hons) MCOptom answers this question.
For holding a book in a normal position for reading, the light should ideally be over the shoulder and slightly behind. The new LED bulbs produce a very white light, use very little power, do not get hot and last a very long time. There is some more useful information on the website below for those who have impaired vision.
