Wearing sunglasses can dark adapt your eyes. Consistently wearing sunglasses can significantly prevent light across the visible spectrum from entering your eyes which can make you even more sensitive to light. This increase in light sensitivity could more easily trigger migraine symptoms and increase light-triggered pain. If you're currently wearing sunglasses, or dark glasses, indoors, wear Avulux for at least 2-3 weeks to allow your eyes to adapt to the lighter tint.
