Mr. Lincoln's glasses

[Eva Elisabeth]

THANK YOU, Tom!!! Great info! I couldn't find anything historical, only that blue-tinted lenses are endorsed by the USPTA for tennis professionals and were provided to linepersons in the 2000 French Open. Blue is a contrast lens and reduces glare from visible white light (such as light reflected from mist, fog, snow, water).

Also I found out blue eyeglass lenses are prescribed when computer and smartphone screens cause “visual stress”, i. e. symptomes like dizziness, discomfort, nausea and shooting eye pain.

Neither the French Open nor computer screens were certainly an issue in the CW era...

(Recommend for golf BTW: smoke/grey on sunny days and amber or yellow on cloudy days.)

I wonder if a photo of Lee exists wearing these blue glasses?
