Thinner is usually considered preferable when it comes to lenses. We are offering an ‘index upgrade’ on all Nikon lenses until the end of December 2014.
The index is the density of the lens and the higher the number, the thinner and lighter the lenses for example, pay for 1.5 and get 1.6. It includes all types of lenses including varifocals. If you are looking to update your spectacles, come in and see us before the end of November to benefit from this offer.
