*Online prices quoted include ​our ​standard index lenses​ [up to a 1.6]​ which is suitable for people with a prescription SPH up to  -/+ 3. For those who have a stronger prescription, need ultra-thin high index lenses​​, multi-focal or other more complex lenses we can definitely do this at an additional cost​; though we will need to see you face to face in one of our boutiques in London to take additional measurements. We won't be able to accept your order without these optical measurements. For more information on this please make sure you read our FAQ section.
