We now have another condition that may be prevented by eating a healthy diet, exercising, and abstaining from smoking: Age-related macular degeneration (AMD).
Macular degeneration causes a loss of central vision and makes it difficult to recognize faces and read small print. The macula degenerates with age and severe macular degeneration causes blindness. Treatment is costly and doesn’t work very well.
A new study published in the Archives of Ophthalmology looked at 1,313 women aged 55 to 74 years. They reviewed their diet and exercise habits. Eating a “healthy diet” meant 3.5 servings of fruit and vegetables, 2.3 servings of dairy, 2.7 ounces of meet and 3.5 servings of grain a day. Exercise habits and smoking history were also monitored.

NASA, in an attempt to have visually-impaired people get a glimpse of what’s “out there,” has created a reconstruction of a Hubble image of the Carina Nebula in a 3D touch map.
Different textures applied to the image help in identifying the various parts of the giant dust cloud. We even think that visually-okay folks can get a better sense of the cosmic anatomy when offered such a presentation.
Read more on this from NASA here.

Researchers at the University of Florida in Gainesville have developed a vitamin E-secreting contact lens that can bring the valuable antioxidant directly to eyes.
Vitamin E is packaged into clusters within the lens and the aggregate works to slowly release the chemical while remaining invisible to the eye.
“These vitamin structures are like ‘nanobricks’,” said Anuj Chauhan, Ph.D., lead researcher of the study. “The drug molecules can’t go through the vitamin E. They must go around it. Because the nanobricks are so much bigger than the drug molecules -– we believe about a few hundred times bigger –- the molecules get diverted and must travel a longer path. This increases the duration of the drug release from the lenses.” Read more »
