Foster Grant reading glasses are available in different strengths. What do these do?
Answer = Magnify the image
"Subtracting 1 from the diopter strength gives you the percentage by which the glasses magnify an image. For example, a strength of 1.25 increases magnification by 25% (1.25 -- 1 = .25). A strength of 4.00 increases magnification by 300% (4 --1 = 3)."
We have 17 pairs of Foster Grant reading glasses - each worth £18.50 - with winners able to choose from either Barrie (men's style) or Cooper (ladies style).
