1.74 Ultra-index Transition RX (Gray / Brown)
High index lenses with 1.70 high index and 1.74 are the thinnest lenses on the market, and are made only for people with the highest prescriptions. If your prescription is lower than +/-6.00 sphere, there is no need for you to spend the extra money for an ultra high index lens. If you do have a strong prescription, however, the 1.70 and 1.74 high index lenses will be a good deal thinner than the 1.67 and 1.60 high index lenses; the higher your prescription, the thinner the lenses will be.
