My Partner And I chose to put Tajima lenses in our high end frames, and have loved every minute of having them. Personally living on the ocean I have had issues in the past with previous lenses easily becoming scratched, and also due to prolonged exposure to the glare of the ocean having headaches. I am a pretty extreme case for wear and tear and having Tajima installed for over 6 months now I am astounded how well they are lasting and have virtually remained scratch free. Spending so much time on the water I chose the Blue lenses and they are truly remarkable and a complete game changer for navigating in Tropical locations. I would highly recommend their products and like this opportunity to personally thank Tajima for producing such a great product and service.
