Does any company make a device that shades computer screens so it’s possible to work outdoors or even in filtered sunlight? I tire of fruitlessly searching for the cursor with a blanket thrown over my head and laptop like an old-fashioned photographer prepared to pop off a flash. I yearn to work outdoors or in the cockpit of my sailboat. Even inside the boat when the hatch is open it’s difficult to see. Next computer will have a daylight-friendlier screen. Any recommendations on preferred brands?
