Although contact lenses have been around for more than a century, the past decade has seen tremendous developments in lens materials and design to bring even greater benefits to contact lens wearers.

Today, almost all eyesight conditions can be corrected with contact lenses. Despite advances in spectacle lens technology and the advent of surgical techniques such as laser refractive surgery, contact lenses provide many advantages and a very successful form of vision correction. New manufacturing technology has also made contact lenses more affordable than ever before. That's why there are now 3.7 million contact lens wearers in the UK, which represents nine per cent of adults aged 15-64 years.

 

Contact lenses offer natural all-round vision whilst enhancing your appearance
• Contact lenses are simple and convenient to use and expand lifestyle choices

• Contact lenses offer a safe, effective, stable, and reversible alternative to refractive surgery
• Contact lenses can correct almost all eyesight conditions and are suitable for people of all ages
• Adaptation to contact lenses is rapid and trouble-free
• The latest contact lenses and solutions provide excellent comfort and eye health
