We get this question quite often: what’ the PD? The pupil distance (PD) is the distance between the pupils, measured in millimeters.
The PD is used to make sure your children’s prescription lenses are centered properly in relation to their eyes. With your kid’s prescription lenses properly centered, they will be looking through the optical center of the lens, giving them the sharpest image and most comfort.
Our high-tech world is affecting our children’s eye health in a massive way. 36% of children are exposed to two hours of digital media each day. As a responsible parent, you need to take immediate and deliberate action to maintain your child’s overall health.
More than half of children experience symptoms of digital eye strain. After prolonged exposure to screens and other devices – all which sit close to the eye – the eye’s auto-focus system (known as “accommodation”) becomes stiff and locked in place. Now, distant objects will appear blurry, and the eyes will feel strained when refocusing on distant objects. This excessive strain on the eyes will manifest itself in various forms, such as:
• Headaches – especially common in the temple or upper neck area.
• Dry , itchy eyes – while staring we blink less, and this dries out our eyes and causes them to itch.
• Fatigue and malaise – poor vision causes squinting and bad posture, tiring the muscles around the eyes and face, straining the body and reducing natural energy levels.
