Used to have a major problem when rotary cutting in my kitchen under the florescent lights. The glare coming off the rulers had me moving my head all around so I could see the measurement marks. Must have looked funny! It became such a nuisance that I got a can of Minwax Polyurethane Clear Satin spray and gave each ruler 2 thin coats. The difference is remarkable as you can see. I know Olfa now makes a frosted ruler but the frosting is on the bottom for gripping fabric and doesn't solve the glare.
