Adlens®, the global leader in adjustable focus eyewear, has announced a second version of Adlens Interface ™­­, the optical solution that protects eyes from 80% of the most harmful artificial blue light¹ emitted by digital screens.

Artificial blue light is a leading cause of digital eye strain, a physical discomfort that can be felt after prolonged exposure to digital screens. Due to the temporary nature of its symptoms, which include dry eyes, blurred vision, eye fatigue, and headaches, many people do not immediately recognise digital eye strain as a serious issue. However, if left unaddressed it may cause permanent cellular damage to the eye’s retina² and lower the production of melatonin, the hormone that regulates sleep, causing disruption to the circadian rhythm³.

With eyes ill-equipped to look at digital screens for the amount of time habitual users’ demand, Adlens Interface is a protective optical solution. Its tinted lenses filter out 80% of the most harmful blue light, easing the temporary symptoms of digital eye strain and reducing the chances of long-term damage to the eye.

The new variation has an adjustable dioptre range of 0 to 2.75 to allow even easier focus on computers and hand-held devices, reducing the strain put on muscles in the eye when focusing on screens for extended periods of time.

Dr Karen Fitchett, Director of Product Management at Adlens, said: “We were thrilled with the reaction to Adlens Interface, with patient testimonials commenting on the noticeable reduction of digital eye strain symptoms and improved screen clarity.

“User focussed technologies, including computers, smartphones, and tablets, have placed new demands on our eyes to remain focused for prolonged periods of time. We decided to introduce a second design to simplify focusing on the distances required by digital devices to help reduce the strain and discomfort that eye muscles experience.

“Protective eyewear is a growing market. However the price, level of protection from blue light offered, and adjustability make Adlens Interface a unique product that will put it in a strong and attractive position among competitors.”

Adlens Interface with the 0 to 2.75 dioptre range will be available from November 2015.
