Blue light is the portion of the visible light spectrum that has the shortest wavelengths and the highest energy. While blue light is important in regulation of your body’s natural wake and sleep cycle, too much exposure can negatively affect your vision.
You are constantly exposed to blue light, both indoors and outdoors. Sources of blue light include:
Our eyes are not good at blocking blue light. Virtually all visible blue light passes through the cornea and lens, and reaches the retina.
With its short, high energy wavelengths, it scatters more easily, and is not easily focused. This causes reduced visual contrast, which can lead to digital eyestrain. Over time, cumulative exposure to this hazardous blue light may damage the retina and put you at risk of vision degeneration.
The macula in the eyes is responsible for sharp and detailed central vision. It is made up of three xanthophyll carotenoids, lutein (L), zeaxanthin (Z) and meso-zeaxanthin (MZ), which are collectively known as macular pigment (MP). This MP protects the photoreceptor cells in the retina against harmful light.
MPOD refers to the levels of MP in the eye. A high MPOD is required to provide higher level of protection for the eyes. MPOD can vary from person to person. It can be affected by several factors including ageing, lifestyle and dietary choices.
L and Z cannot be synthesised by your body; they can, however, be obtained through diet. Foods rich in L and Z include kale, spinach, turnip greens, green peas, broccoli, corn and eggs.
Unlike L and Z, MZ is not present in a typical diet. It is produced in the retina from L via an isomerisation process. However, this process is disrupted as you age. It is therefore essential to replenish these carotenoids, particularly MZ, through supplementation.
The different absorption spectra of L, Z and MZ results in a collective optimal filtration of blue light at the macula, which would not be achieved by any of these carotenoids in isolation. Studies have also shown that the inclusion of MZ resulted in a greater increase in the MPOD in comparison to supplements lacking this central carotenoid.
MZ accounts for about one third of total MP at the macula. It resides directly over the center of the macula, where light is focused and where the strongest need for blue light protection exists.
Moreover, of the three carotenoids, MZ has the greatest capability of quenching oxygen radicals. It has the capacity to filter the most energetic and potentially damaging wavelengths of visible light, and to neutralise free radicals.
VitaHealth Eye-Pro is formulated with patented scientifically proven ingredient – XanMax® Marigold extract, standardised to deliver optimum amounts of L, Z and MZ for maximum eye protection and antioxidant support.
