Normally it makes no difference as to whether it is summer or winter using a laptop outside means not being able to see the screen very clearly. If you put sunglasses on the screen will go even darker, that leaves the Glarewear sunglasses, these do the job apparently.
The sunglasses have been made to make the LCD screen shine through the lenses while blocking all other light. Just in case your laptop screen emits a different type of light, the Glarewear glasses come with three sets of lenses, just choose the best one for your laptop.
