Prevent Macular Degeneration & Correct Your Eyesight With These 5 Foods

posted on 8/5/2016 Facebook Facebook

Eyes are our own little windows to the world. However how many of us have a regime to detox our eyes when we spend hours in the spa detoxing our skin and grooming our hair. With an increase in the amount of time that we spend staring at computer screens or cellphones, the incidence of eye strain and fatigue correspondingly increases. Our eyesight also naturally diminishes as you age which further adds to this deterioration. 

Age related macular degeneration (AMD) is a common cause of blindness in older individuals and typically affects people over the age of 50. It mainly affects central vision, which is needed for detailed tasks such as reading, driving, and recognizing faces. However, side (peripheral) and night vision remain unaffected. There are several factors which elevate the risk of AMD however, newer scientific evidence has been able to pin point a strong affiliation to one’s genes. The risk of developing the disease is three-fold higher in people who have a family member with AMD than in those without a first-degree relative with AMD. 

Since 2005, several genetic variants have been consistently associated with AMD. The common coding variant Y402H in the complement factor H (CFH) gene was the first identified. Thereafter, scientists are studying other gene candidates to determine their role in this disease. While a genetic component does contribute to one’s risk of developing macular degeneration by anywhere from 40 percent to 70 percent, it’s development is due to a combination of lifestyle, genetic and environmental factors. 

Genetic testing for AMD can help assess your risk, particularly if you have a immediate or close family member suffering from the disease. Modifiable risk factors such as healthy diet, exercise etc. can help you curb the risk if detected and protect your eyesight. Similarly visiting an ophthalmologist to have a look at your eye from time to time can also serve to keep any eye problems in check. 

We have all grown up to simple home tips which our mother’s kept us reminding from time to time to keep our eyes safe. Here are five foods which you can add to your daily diet to keep your peepers healthy and free from any vision threatening diseases. 

1.Almonds
Rich in vitamin E, these wonder nuts can slow macular degeneration and protect you against cataract as well as glaucoma. An ounce of almonds is equal to your daily dose of vitamin E.

2.Fatty Fish
Coldwater fatty fishes such as salmon, mackerel, tuna, sardines and trout are rich in DHA (fatty acid), which is an integral part of your retina. A low level of this fatty acid has been linked to dry eye syndrome. 

3.Berries
A chock full of anthocyanin and vitamin C which are powerful antioxidants, blueberries, strawberries, goji berries, and raspberries aid in improving your vision by supporting cell membranes in your eyes.

4.Eggs
The yolk is a prime source of leutin and zinc which has been shown to reduce the risk of developing macular degeneration and cataracts.

5.Fresh Vegetables
Dark greens, carrots, peppers, and sweet potatoes are all rich in powerful antioxidants like beta carotene, zeaxanthin, and leutin which help in defending against age related vision problems and also lower the risk of cataracts.
