Yes, they are. If you order prescription lenses of any type, including blue light and sunglasses, you are allowed to use your HAS or FSA account to pay for them. It is good to spend your health savings on high-quality eyewear.
However, you can not use your FSA or HAS account on non-prescription eyewear. If you need help placing an order using insurance or your FSA and HAS account, don’t hesitate to contact their support team by sending an email to hello@liingoeyewear.com.
