Rise in incidence of eye strain
With the demands of the modern world and digital technology many adults are living with some kind of eye strain including tired eyes, blurred vision and dry eye.
A recent study showed that all users of digital devices – regardless of their age, the type of device used and the frequency of use, feel the same discomfort, related to the difficulty of reading small characters and screen brightness. However, the level of discomfort varies depending on the user’s age. In fact, for younger users, the main discomfort is screen brightness, while for older users, it is the effort required to decipher the small characters.
To meet these new visual needs, Essilor, world leader in spectacle lenses has designed a new category of lenses for a connected life. This all-new range of spectacle lenses provides a correction for each reading distance required by digital devices, relaxes users’ eyes and protects them against the potential dangers of blue-violet light.
The number of Kiwis seeking help for digital eye strain is growing year-on-year with international studies showing 70 per cent of device users are adversely affected.
Visique Optometrist Cherie Southall says a significant number of people are reporting longer time spent in front of digital screens and she is seeing more people suffering from blurred vision, dry eyes and headaches caused by strain.
The exciting new Eyezen lenses have two new technological features designed to support users in keeping their eyes relaxed and comfortable. Eyezen eases stress on the focusing system when switching from one type of screen to another.
‘‘We can prescribe your specific Eyezen lenses, regardless of the size or the distance you are from the devices,’’ says Cherie.
The second innovative feature of Eyezen is a light scan technology, which selectively filters blue light, helping protect eyes from the harmful effects of blue-violet light rays.
Visique Optometrist Brian Naylor says over exposure to blue-violet light is a potential concern and is linked to headaches, dry eye, and sleeping patterns.
‘‘Blue-violet light is a proven risk factor for Aged Related Macular Degeneration along with genetic factors, smoking, and diet.’’
Crizal Prevencia, the surface lens treatment that selectively filters blue light is being increasingly prescribed at Visique Naylor Palmer for children, teenagers and young adults who are actively using devices.
Visique Naylor Palmer and Eye Spy Optometrists recommend an eye examination every two years or at least annually for those with higher risk factors.
Spending a lot of time in front of computer screen is leading to more and more New Zealanders seeking help for digital eye strain.
