Understanding Astigmatism
Astigmatism is a common eye condition, in this article we explain the causes through to how it can be treated.
At Essilor, we have created enhanced single vision lenses to deal with the challenges of modern-day life. These lenses are known as Eyezen.
Eyezen lenses are designed to accommodate for new visual and behavioural standards that come from using digital devices on a regular basis. Our eyes are not naturally equipped for the digital age, and looking at something close-up for longer than 20 minutes can result in weaker vision, eyestrain and headaches(1).
The majority of us will use digital devices for hours every day, whether it’s for work or leisure. With that in mind, this connected lifestyle has created the need for lenses that support it. Eyezen lenses can achieve this.
The modern lifestyle can have an impact on your vision, which has resulted in the demand for a new standard of lens to reduce the strain on your eyes. Eyezen lenses are unique in their ability to support your eyesight and deliver sharper vision than ordinary single vision lenses(2).
Using digital screens can be tough on your eyes as they deal with pixelated characters and switching between variable distances. In some cases, smartphone screens can refresh up to 60 times per second, leaving your eyes tired as they have to refocus each time.
Alongside correcting your eyesight, Eyezen lenses are perfectly optimised for digital devices, resulting in a modern lens design.
Light is crucial to our vision, but some of the light spectrum can cause premature eye ageing. Blue-Violet light, in particular, can cause damage to retinal cells(3).
Our Eyezen lenses can be combined with the first embedded filtration system, Eye Protect System. This provides protection against harmful light, including UV and Blue-Violet light.
If that wasn’t enough, Eyezen lenses are available with AVA technology; Advanced Vision Accuracy. After 5 years of scientific research, we have discovered a highly accurate and simpler way of testing your vision.
Our partner opticians now have the ability to measure your eyes to 0.01D (the measurement of the prescription required to correct your eyesight), instead of being rounded up or down as done previously. This results in high precision lenses with no restrictions.
Eyezen lenses are optimised to reduce or even prevent eyestrain, offering comfort throughout the day. Eye fatigue can be detrimental, manifesting itself through tired, itchy or burning eyes(4). Even with a balanced life between screens and outdoors, your screen time has an impact on your vision(5). By wearing the right lenses, you can reduce the effects of this and get on with your day.
Specifically created to meet today’s demanding visual standards, Eyezen lenses benefit from an enhanced design that allows you to continue to do what you enjoy.
