My son has been diagnosed with surfer’s eye… so needs to wear sunglasses all the time in summer months especially. He plays football competitively and so I need to find some good sunglasses with foam protection, sports strap which have high up protection that will fit his relatively small 10yr old head! I can’t find anything very easily. Maybe I need to go with him to an optician but I have never worn glasses so have no sense of which optician is likely to have best ‘sport’ and ‘child’ options. Any advice very great fully received!
