Because the product range is wide, in addition to the fact that you can order products around the clock, availability is an advantageous feature of purchasing via the internet. Prices' are generally, significantly cheaper than those offered by opticians.
The reason for this is that retailers often maintain larger stocks of lenses, and thereby can deliver more quickly to customers than any other type of outlet. In addition, many internet retailers have lower premises costs than traditional opticians and sell primarily only lenses as opposed to opticians, who also sell spectacles.
Any careful examination indicates that the customer makes greater savings on the Internet than with a traditional optician. That said, it is essential that the customer when considering a particular product takes careful note of the delivery fee, prior to actually ordering.
Even if a customer should purchase their lenses on the Internet it is to be recommended that they maintain regular contact with an optician as eye capacity is subject to ongoing change. Different retailers' also have different rules as to whether a customer requires an opticians prescription so as to be permitted to order lenses or not. Regardless of the terms and conditions set by the retailer it is recommended that customers have their eyes tested on a regular basis.
