I have bad light sensitivity and have been wearing very dark sunglasses with DIY window tint applied to them to make them even darker, but I still experienced glares that were excruciating and gave me headaches. Good ole ChatGPT recommended these sunglasses instead, and I've learned that the light sensitivity is the lesser of the problems I have, it's primarily a glare problem from certain TYPES of light, and these lenses remove that. They are great! I have a small head but they fit well enough, even with my long lashes, and my husband can wear them with a regular sized head too. :) Shipping was relatively fast, faster than the estimate.
