If you have to buy prescription lenses and can only afford one set like me, or non RX and don't want to buy more that one then, I would go with the amber. They are great in the very low light of dawn and dusk and are sufficient for bright flats days. There are times when I wish I had a darker lens during those high light days but the flexibility in low light, mornings, clouds and evenings more than make up it. They see into the water very well and I have had now trouble marking fish in bright conditions. Tilting your head is a good tool also, to filter glare from a low angle especially early morning.
