Apple's Visual Discomfort Recommendations - Use Of Computer Glasses!

"Using computers for extended periods can cause visual discomfort, headaches and vision challenges. It is very unlikely that you will suffer permanent changes or damage to your eyes. Rather, you may experience these symptoms whenever you use a computer intensively for periods of a couple of hours or longer; the symptoms will diminish soon after you stop working on the computer. Typical symptoms of vision challenges include:

Eye strain refers to ocular fatigue, eye discomfort and headaches associated from intensive use of the eyes. Common causes include:

* Glare on the computer screen.
* Poor visual correction (out of date eyeglass prescription).
* Reading small character sizes on the screen.
* Poor contrast between text and background on the monitor.
* Noticeable screen flicker.
* Dry eyes.

Blurred vision can be caused by normal physiological changes in the eye (i.e. aging or disease). It can also be caused by constant focusing on objects within 12" of the eyes, which often occurs when reading in low light.

Dry and irritated eyes occur when there is insufficient fluid in the eyes to keep them moist. Eyes are kept moist and refreshed by a normal blink reflex which is present from birth. Blink rates vary with different activities and can become slower when concentrating. Eyes can become red and itchy. Common causes include:

* Reduced blinking when using the computer.
* Air movement that is noticeable in the face area."

Sounds like Apple users need Gunnar Optiks' fRACTYL lens geometry & iONik lens tints! Details below:

iONik lens tints:

With advanced spectropotometry, Gunnars lab technicians have the ability to study and analyse even the most difficult lighting environments. Each part of the visible and invisible light spectrum can be measured and quantified. To balance and optimise that lighting environment for the needs of the human eye, the Gunnar lab techs then use a combination of iONik lens tints and i-FI coatings.


* Tints tuned to specific environments for maximum visual efficiency.
* Captures and enhances 'good' light to increase ocular endurance.
* Reduces high energy visible light to speed visual recovery.
* Enhances contrast for a sharper viewing experience.

fRACTYL lens geometry:

Designed using advanced computer algorithms, fRACTYL lens geometry mimics nature by focussing light. The highly wrapped configuration creates an ocular microclimate trapping in humidity and blocking out evaporative air currents.


* Precisely tuned to specific distances for reduced visual stress.
* Advanced optics for augmented details.
* Independent ocular microclimate provides increased humidity levels.
* Environmental barrier blocks ambient air currents to alleviate dry eye effects.
