If you've never had a hearing aid before, you'll appreciate our caring and compassion.
Please take a look at our section 'Before you get a hearing aid' which will answer many of the questions you might have.
Hearing Care & Optics
Purchasing a hearing aid can be a confusing process. We try to make it as easy as possible and help you make decisions based on YOUR best interest
What is Blue light
Blue light is actually everywhere.When outside, light from the sun travels through the atmosphere.
Blue light is actually everywhere. When outside, light from the sun travels through the atmosphere. The shorter, high energy blue wavelengths collide with the air molecules causing blue light to scatter everywhere.This is what makes the sky look blue. In its natural form, your body uses blue light from the sun to regulate your natural sleep and wake cycles.This is known as your circadian rhythm.Blue light also helps boost alertness, heighten reaction times, elevate moods, and increase the feeling of well being. Artificial sources of blue light include electronic devices such as cell phones and laptop computers, as well as energy-efficient fluorescent bulbs and LED lights.
Why should we be concerned about blue light exposure?
Blue light waves are the among the shortest, highest energy wavelengths in the visible light spectrum.Because they are shorter, these "Blue" or High Energy Visible (HEV) wavelengths flicker more easily than longer, weaker wavelengths. This kind of flickering creates a glare that can reduce visual contrast and affect sharpness and clarity.
This flickering and glaring may be one of the reasons for eyestrain, headaches, physical and mental fatigue caused by many hours sitting in front of a computer screen or other electronic device.
Our eyes' natural filters do not provide sufficient protection againstblue light rays from the sun, let alone the blue light emanating from these devices or from blue light emitted from fluorescent-light tubes. Prolonged exposure to blue light may cause retinal damage and contribute to age-related macular degeneration, which can lead to loss of vision.
Blue Light: It's Both Bad And Good For You
Visible light is much more complex than you might think.
Stepping outdoors into sunlight; flipping on a wall switch indoors; turning on your computer, phone or other digital device — all of these things result in your eyes being exposed to a variety of visible (and sometimes invisible) light rays that can have a range of effects.
Most people are aware that sunlight contains visible light rays and also invisible ultraviolet rays that can tan or burn the skin. But what many don't know is that the visible light emitted by the sun comprises a range of different-colored light rays that contain different amounts of energy.
