This is an excellent company to deal with . My son trains 5 days a week and because he's short-sighted was struggling to see the clock and check his times. I didn't know where to start with prescription goggles. I found Swan online and liked that you could choose different prescription for each side . I wasn't confident what to order for goggles despite being armed with his current contact lens prescription. I emailed and received a very prompt reply.....including a suggestion as to what style to go for . The goggles arrived and have been a game changer. My 14 year old loves them ! Not just because he can see but because they also look quite cool . Phew ! Great service ,great product and not too expensive . Thank you so much .
