Is there a way to get the lenses with my prescription to go with these sunglasses?

Aloha! It is possible to purchase prescription lenses for the Red Sands style, however you would need to work with a Maui Jim Sunglasses authorized optical retailer in your area. Since our prescription lenses are considered a medical device, they must be handled through a licensed optician's office. To find optical retailers near you, please visit https://www.mauijim.com/US/en_US/store-finder/position#start, enter your zip/postal code, and filter by ‘Sunglasses with Prescription’. These retailers will be able to assist you in checking the compatibility of your prescription with your sunglasses, purchasing a pair of authentic Maui Jim prescription lenses, pricing questions, lens colors and options, and availability. Mahalo!

Which would be better for a small/medium size face. Legends, red sands or mcgregors?

Good Morning,The Legends is 54mm, Red Sands is 59mm, and the McGregor Point is a 58mm. So basically the Legends is small/medium, the other two are on the larger side of medium close to large.Hope this was helpfulEJ's SunglassesAuthorized Maui Jim Dealer
