As the world commemorates World Sight Day and focuses on the importance of eye care in the workplace. Choosing the right spectacle lens design may help improve visual comfort in the workplace.

In today’s digital age, the workplace has undergone significant changes. Many jobs require employees to spend long hours in front of screens and other digital devices. This shift raises concerns about the impact of extended screen use on vision health.

An employee’s vision is crucial for their overall well-being and productivity, it is essential for both employers and employees to prioritise vision health in the workplace.

The Importance of Vision Health

Comfort and Wellbeing: Prolonged screen time can cause eye strain, dryness, and discomfort, collectively known as Digital Eye Strain (DSE). The symptoms can impact an employee’s overall wellbeing, leading to fatigue, headaches, and decreased job satisfaction.

Safety: In many industries, safety is paramount. Impaired vision can pose a significant risk, particularly in jobs that involve operating machinery, driving, or working in hazardous conditions. Ensuring good vision is crucial for preventing workplace accidents.

Productivity and Performance: Clear, healthy vision is a cornerstone for workplace productivity. Employees who experience vison problems may struggle to read documents, view screens, or perform tasks that require attention to detail. Poor vision can lead to errors and decrease overall performance.

Digital Eye Strain

Digital eye strain is eye discomfort, and other symptoms, that arises from prolonged use of digital devices. While most symptoms are temporary, they can cause significant discomfort routinely.

Symptoms include:

  • Dry, itchy eyes.
  • Blurred or fluctuating vision.
  • Headaches.
  • Increased sensitivity to light.
  • Neck and back pain.

There are things that can be done to reduce the effects of digital eye strain in work.

  • Take regular breaks from looking at screens by observing the 20/20/20 rule.
  • Make sure screens are clean and text is in sharp focus.
  • Adjust the brightness to suit the environment.
  • Make sure the display font is a comfortable size to read.
  • Stay hydrated and use lubricating drops to soothe dry eyes.
  • Ensure any spectacles are the most recent prescription.
  • Speak to an Optometrist about any concerns.

Spectacle Lens Choices

Caledonian Optical offer lenses suitable for all prescriptions, manufactured with cutting edge Digital RayPath 2 technology. This technology reduces distortion and acts as an ultra-HD filter, sharpening focus and providing a wider, usable area in the lens.

The HD:SV 2.0 is an innovative single vision design. Suitable for all single vision wearers, this design reduces distortion and provides a high-definition solution to increase visual comfort.

Varifocal wearers sometime find the intermediate, or computer, area doesn’t provide as wide a field of view as they would like when using their computer for an extended period. Caledonian Optical’s Office 2.0 lens is a great solution.

The Office 2.0 lens is designed for presbyopes (people who require spectacles for close work) who spend time working at distances of arm’s length or closer. It provides a wide field of view for computer when looking straight ahead and the boost they need for close reading towards the bottom. These lenses do not correct any prescription which may be required for TV or driving, dedicating the whole lens to the near tasks at hand.

Anti-fatigue lenses can help for patients aged between 18 and 45 who may not need any specific correction for close work but still suffer with the symptoms of digital eye strain. The Serene 2.0 lens corrects any distance prescription which may be present with the benefit of a “boost” in the lower part of the lens. This boost helps the eye muscles focus the image, therefore reducing strain.

Alongside these pioneering lens designs, Caledonian Optical provide additional lens treatments such as blue filters and anti-reflection coatings. The Diamond coating helps cut down glare produced by your devices, allowing a sharper image to reach the eye, improving comfort.

Sunlight is the main source of blue light; however digital devices do emit low levels too. Blue filter lenses help reduce exposure by up to 20% which can contribute to reduced feelings of eye strain and fatigue.
