The Story of Light
The Lens
Prescription lenses bring our world into focus. RX Lenses help us work, play, and learn, but the story doesn’t end there.
The Story of Light
Everything interacts with light. When light hits an object, that item either transmits light, absorbs light, or reflects light. A leaf, for example, absorbs some light and reflects the rest of it and this reflected light determines what color we see. Green is not actually “in” the leaf. The surface of the leaf is reflecting the wavelength of visible light we see as green and absorbing all the rest. An object appears white when it’s reflecting all color. An item is black because it’s absorbing all the light.
What happens to light with an optical lens?
Prescription lenses help us focus by altering the direction of light rays to focus light properly onto the retina of our eye. But, just like the leaf, lenses in eyeglasses actually reflect a certain percentage of light away from our eye. This means eyeglass wearers are not receiving all available light, which can be a real disadvantage, especially in low-light situations. And because eyeglass lenses come in a wide-range of material, there are varying degrees of light loss.
How Can A Lens Be Enhanced
Did you know that eyeglass lenses can be enhanced to allow more of the best light to reach your eye? Today’s optical advancements can allow more light to be transmitted through the lens to your eye. Similar technology is available to reflect or absorb unwanted light. Light Enhancing Technology is achieved by applying a thin film coating to the lens which alters the light waves to achieve the desired result.
Transmission
A Light Enhancing Technology that increases transmission can be applied to your lens as a thin film coating such as the Quantum Sentinel UV which increases light transmission up to 98%.
Reflection
A Light Enhancing Technology can also be applied to a lens to increases reflection which reduces light on a bright, sunny day.
Absorption
Another popular issue right now is how to have your lenses absorb blue light associated with cell phones, tablet devices, LED TV’s and even billboards. This can easily be achieved with a Light Enhancing Technology like Quantum’s new Energy Absorbing Technology (or E.A.T.).
More about light
Light is so common that we rarely think about what it really is. But just over two hundred years ago, a groundbreaking experiment answered the question that had occupied physicists for centuries. Is light made up of waves or particles? Check out the double slit experiment.
