The environmental conditions can lead to dry eyes. If you are out in sunlight without sunglasses or any other type of protection for your eyes then you could dry out your cornea. That causes dry eyes. The wind can cause dust as well as other debris to fly through your eye, thereby wearing eye protection is necessary.
The heat generated by the hairdryer and being in front of a blower and driving with the window open may cause dry eye conditions. Be conscious of your surroundings to keep your eyes safe from getting dry and becoming sensitive. This can cause itching that can cause scratches to the inside of the eye.
