There are many different eye diseases, conditions and disorders that can affect your eyesight, cause visual impairment and, ultimately, can lead to a complete loss of vision. Not all eye diseases and conditions have noticeable symptoms; this is why it is so imperative to have regular eye examinations and checkups as early detection often makes treatment far easier and more effective. Common symptoms of having an eyes disease include; seeing flashes of light, double or blurred vision, inflammation of the eye, excess fluid coming from the eye and unusual pain in the eye. If you experience any of these conditions then immediate medical attention should be sought.
Glaucoma is the second commonest cause of blindness; cataracts being the first. Glaucoma has been nicknamed ‘The sneak-thief of sight’ as it is often a slow and gradual progression that leads to optic nerve damage and can therefore often go undetected until it is too late and damage has already been caused. This is why it is so important to have regular eye examinations and checkups by your opthamologist or eye specialist. Gradually, over time, glaucoma will lead to the loss of ganglion cells in the retina of the eye which project the images we see to the brain. These cells convert the images that we see into very small electrical impulses which the brain then translates into what we perceive as our sight. When these cells become.
The macula is a highly pigmented, oval-shaped, yellow coloured spot near to the centre of the retina of the eye and is approximately 5mm in diameter. Its yellow colour comes from its high concentrations of zeaxanthin and lutein which are yellow xanthophyll carotenoids. Because of this yellow colour it absorbs excess blue and ultraviolet light which acts as an effective sunblock, much the same as sunglasses, to protect this part of the retina from damage. As we age, a lack of these two essential carotenoids which we usually obtain through our diet causes the macular pigment density to lessen which, in turn, reduces it effectiveness as a sunblock and then the macular can become damaged. Daily supplementation with zeaxanthin and lutein will help to restore the macular pigment density and ensure that the macular is effectively.
