Contact lens wearers have been urged by a financial journalist to use the internet to save money.
Writing for the Daily Mail, Liz Phillips said that it is less expensive to buy contact lenses online.
She did note, however, that fitting advice and details first need to be obtained from an optician and regular checks are important.
Consumers should be careful to enter the correct prescription details and check the refund policy before they commit themselves to a sale.
Ms Phillips also gave some tips on saving money on glasses.
She reminded readers that it is not necessary to buy new frames if only the lenses need replacing and noted that frames are also cheaper when bought online.
Consumer group Which? says that it is usually cheaper to buy contact lenses and glasses online.
It advises people to check that their contact lenses are the correct prescription, base curve and lens diameter.
