Why do I need blue control glasses?
Using your computer or smartphone for hours each day can have long-term effects on your vision.
We use these devices at work, on the road and at home, often holding them at a short distance, so our eyes have to constantly refocus.
Digital devices, LCD and LED screens, fluorescent and LED light globes emit blue light and protecting your eyes from this high-energy visible (HEV) light can significantly mitigate the risks of retinal degenerative diseases.
Why is blue light harmful? It’s natural light, isn’t it?
Blue light is a naturally occurring light. Its short, high-energy blue wavelengths collide with air molecules, causing blue light to scatter everywhere; that’s why the sky looks blue.
As this light is emitted from the sun, we naturally align our sleep cycles to its stimulus. Using tablets or computers late at night may lead to difficulty falling asleep.
Blue blue light scatters more easily and is not as easily focused, so less contrast is visible to the eye, causing strain on our eyes. This particularly affects people who work most of the day looking at smartphones or computer screens that emit significant amounts of blue light.
Many people also suffer from red, irritated eyes, eye fatigue, headaches and blurry vision during or after using digital equipment. the discomfort level only increases with the amount of time spent on a screen.
Prolonged exposure to blue light can damage light-sensitive cells in the retina and the macular pigment. Severe damage can lead to macular degenerations, glaucomas, and retinal degenerative diseases – loss of vision.
Protecting your world view
While we all know that we need to wear sunglasses for protection from sunlight. We now understand the need to wear computer glasses and /or blue light blocking lenses to shield eyes from direct exposure to blue light.
Computer glasses
To protect and enhance your vision we sell a variety of eyeglasses for computer work. Computer glasses differ from regular eyeglasses or reading glasses; they put the optimum lens power for viewing your computer screen in the intermediate zone of vision, closer than distance vision, but farther away than reading or near vision. Computer glasses give a clear, wide field of view, reducing the need for excessive focusing effort. The lenses can also incorporate special filters such as the HOYA BlueControl coating and anti-reflection coatings.
Blue control lenses
Wearing blue control glasses while you use your computer, phone or other devices can prevent headaches, disrupted sleep, dry eyes and eye fatigue.
Our blue control lenses have a coating with Hoya BlueControl finish. They are not only extremely scratch resistant, water-, grease- and dirt repellent, they also neutralise the high energy visible light emitted by LCD and LED screens.
If you spend a lot of time in front of a computer, blue control lenses are a fantastic choice as they offer more comfortable vision and better contrast perception. You’ll definitely notice the difference.
We offer blue control lenses for computer glasses and for most prescription lenses. You will find that your eyes are no longer strained, dry, and irritated after using your digital devices for long periods of time. Furthermore, headaches and sleep problems that arise from overexposure to blue light may no longer be an issue. Blue control glasses greatly eliminate the dangers of overexposure to blue light from digital devices and reduces the likelihood of suffering from macular degeneration later on in life.
Ask us if you’d like to know more about the benefits of blue control lenses and if they’re right for you.
For many people, wearing a pair of blue light filter glasses has been found to help ease eye strain. However, you should see our optometrists if you continue to experience any of the symptoms listed below.
· Dry eyes
· Burning or itchy eyes
· Blurred vision
· Headaches
· Increased sensitivity to light.
