Glassesdirect.co.uk is the world's largest direct seller of Prescription glasses. Prescription glasses are extremely expensive in the UK; following an eye test costing up to £20 a customer can expect to pay from £50 for basic spectacle models and up to £400 for designer eyeglasses and/or complicated lenses. Glassesdirect.co.uk has introduced a new way to buy prescription glasses. Launched in July 2004, glassesdirect.co.uk sells prescription eyewear over the internet and by mail that significantly undercut high street prices, selling a range of eyewear with basic frames and lenses starting at £15, in total. The business is operated maintaining low overheads, and the savings are passed on to the customer.
