Maintaining vision health is vital, especially during the aging process. When light is reflected off of an object, the light waves from the object enter the eye through the cornea, which is the transparent front part of the eye that covers the iris, pupil and anterior chamber. The light is then filtered through to the pupil, which is the black circular or slit shaped opening in the center of the iris that regulates the amount of light that enters the eye. The iris is the colored portion of the eye that controls the pupil. The light then continues through the lens, located behind the iris and pupil, and made up of transparent proteins called crystallins. The light waves are bent or converged by the lens and the cornea to just behind the surface of the lens where it is then reversed and inverted. The light waves then pass through the vitreous humor, the clear gel between the lens and the retina, which is a thin layer of neural cells that lines the back of the eyeball. The macula is a small, yellowish spot located in the middle of the retina that is responsible for the detail of vision by providing visual sharpness and color perception. The retina consists of a large number of photoreceptor cells, which contain a particular protein molecule called an opsin.In humans, there are two types of opsins, rod opsins and cone opsins. Each opsin absorbs a photon (a particle of light) and transmits a signal to the cell through a signal transduction pathway, resulting in hyper-polarization of the photoreceptor. Within the retina, light waves are changed into electrical signals and then sent through the optic nerve , along the visual pathway , to the occipital cortex at the posterior or back of the brain. The brain is what actually reconstructs or interprets the electrical impulses into a picture. The intricate process that contributes to visual degradation usually develops over a long time-period, making the need for a protective eye approach even more important. Free radical activity is a constant factor in the body’s metabolism. Waiting to begin an antioxidant defense against oxidative stress until the prime senior years may be too late. Promoting visual health is important and can be accomplished through a healthy diet, exercise and the right supplementation. Isotonix Vision Formula with Lutein is an isotonic-capable dietary supplement, combining vitamins and minerals with lutein, quercetin, eyebright, zeaxanthin and bilberry, designed to promote healthy vision throughout the aging process. Isotonix Vision Formula helps maintain the structural integrity of blood vessels and capillaries, helps maintain the membranes of cone cells in the eyes, helps maintain lens transparency, helps strengthen the cells of the retina, and promotes healthy oxygen and nutrient flow to the eyes. The antioxidant properties of Isotonix Vision Formula help protect the eyes from oxidative stress. It promotes healthy macular density, promotes healthy vision and supports night vision. Isotonic, which means “same pressure,” bears the same chemical resemblance of the body’s blood, plasma and tears. All fluids in the body have a certain concentration, referred to as osmotic pressure. The body’s common osmotic pressure, which is isotonic, allows a consistent maintenance of body tissues. In order for a substance to be absorbed and used in the body’s metabolism, it must be transported in an isotonic state. Isotonix dietary supplements are delivered in an isotonic solution. This means that the body has less work to do to in obtaining maximum absorption. The isotonic state of the suspension allows nutrients to pass directly into the small intestine and be rapidly absorbed into the bloodstream. With Isotonix products, little nutritive value is lost, making the absorption of nutrients highly efficient while delivering maximum results.
