US study shows exercise can help prevent macular degeneration

Researchers at the University of Virginia have found that physical activity reduces the proliferation of blood vessels in the eyes. This harmful overgrowth of blood vessels is a key contributor to vision loss conditions such as macular degeneration and diabetic retinopathy.


National Park helps blind people on moor

A sight loss charity has received a financial boost from Dartmoor National Park Authority to support blind and partially sighted people living on Dartmoor during the current crisis.

The Dartmoor Coronavirus Community Support Fund has given Devon in Sight a grant of £500 to help people with sight problems it helps take advantage of the latest technology to stay in contact with family and access information as well as resources such as the news and audiobooks.


Newly developed eye-drops can prevent vision loss

Retinal vein occlusion which is a major cause of blindness for millions of adults worldwide can be prevented with a new eye drops solution developed by a team of researchers. A study on mice suggests that the experimental therapy, which targets a common cause of neurode generation and vascular leakage in the eye, could have broader therapeutic effects than existing drugs.


Scientists have found a way to improve age-related vision loss

As we get older, our eyesight is one of the things that starts to go, which is why they say that when we are young, we should take better care of our eyes so that in the future, any issues we have might not be quite as severe. However, thanks to science and technology, perhaps there might be a way to treat it.

In a study published in The Journals of Gerontology, scientists in the UK have discovered that by getting their subjects to stare into a red light emitted at a certain frequency (the light wavelengths were 670nm), it allowed the subjects to see better in the dark while also being able to better distinguish colours.
