I bought this sunglasses from Amazon because of lot of positive reviews ,but this model is only good for people who have small or medium face .. and not that high nose .. since I have big face and high nose ,these sits high on my face and the bifocal line interferes with straight sight .. so either you set the glass low on face , otherwise it is completely not worth ,the polarized portion of 0 lens area is very good ,enhances colours but the bifocal area is too big compared to size of lens .. so interferes in straight and parallel sight view.. so returning it and buying the sunglasses which has lens height of 42 mm or more ..
