Most ask, why sunglasses? I do not have a definite answer but i will say this most of the visual challenges can be prevented (did you know that?) , i had migraine and headache issues while in campus , you know what caused that? light . Out of personal issues an idea was born way later , what can i do to stop the Migraines ? First i had to identify why i was having migraines then come up with solution. Most of my young adult life i was donning sunglasses, i still do but with a purpose to help others take care of their eyes.
