Macula protection and reducing the problems of glare and blue light damage

The use of supplements containing macular pigments is now well established in the UK”, reports Deven Lakhani, Consultant Optometrist at Hammond Opticians.

However the role of nutrition in improving contrast sensitivity and reducing glare in healthy individuals with good vision is less well understood”, he continued.

There are many different preparations available and it is important for people to realise that not all of them will help every individual. This is in part due to the fact that the natural concentrations of the three most abundant pigments in the macula (the central sensitive part of the retina): lutein, zeaxanthin and mesozeaxanthin vary considerably between different people.
 
These pigments are found occurring naturally in some foods within our diet, like green leafy vegetables, yellow and orange peppers etc., but can sometimes be poorly absorbed. Healthy food for your eyes
 
They help the macula by offering a protective filter which can help in reducing the glare suffered due to light scatter from short wavelength light, such as from the headlights of an oncoming car while driving. In fact recent findings suggest nutritional supplementation could reduce recovery time from glare caused by headlights, which could take up to 6 seconds.
 
Furthermore some studies focusing on young, healthy individuals with good vision have shown that nutritional supplementation has improved contrast sensitivity – which has known benefits for sports and driving.
 
A further way to help reduce the ill effects of blue light is to use specialised blue-filter anti-glare coatings, such as Crizal Prevencia, on spectacle lenses. These offer an additional way to counteract the problem faced by many in modern life.”
