*If you buy 2 complete pairs of glasses (frames & lenses) we will give you the lenses in the second pair FREE of charge. That’s a saving of £100 to £700 depending on the lenses you choose. We will give you the exact same value and quality of lenses in the second pair. If you wear single vision lenses, you’ll save between £100 and £450. If you wear varifocals, you’ll save between £250 and £700. You can use your Free Lenses Voucher for any type of lenses in glasses or sunglasses.
