Vitamin D and the Effects on your Eyes

by Robert Green on January 31, 2012

The affects of vitamin D on the human body has been studied since the 1930’s however research is continuously being performed all over the world.  Studies are now looking at the ability of vitamin D to help combat the effects of aging in your eyes.

The most recent issue of Neurobiology of Ageing reports that a study at the Institute of Ophthalmology at University College London has found some promising outcomes with their research.  Although they are still in the stages where they are working with animals they have found some inspiring results.

Without becoming technical on the findings, the researchers found two main areas in which vitamin D showed promise in helping prevent the aging process in your eyes.  The first area they found promise was that the vitamin D helped in the reduction of potentially damaging cells (macrophages).  These cells have been linked to inflammation which is something that we are all aware that we do not want to have taking place in our eyes.  The second area of encouragement the researches saw was a decrease in the amount of  toxic molecule (amyloid beta) deposits.  The deposits of this molecule will collect in your system as you age.

Together these findings are very encouraging because when these two factors come together they are the main cause for age related macular degeneration (AMD).  As you may or may not be aware AMD is the leading cause of blindness for people over the age of 50.

With information from studies such as this showing encouraging results from vitamin D and the effects in could have on your vision your next question may be where are the best sources for vitamin D?  Well you can achieve your Daily Value by more than just your diet although that is a good place to start.

Pure Cod liver oil is one of the best sources of vitamin D. However, if that sounds like something more than you would like to try you can also enjoy a piece of salmon, mackerel or even tuna fish. Milk can be a good source of vitamin D just make sure it is fortified with the vitamin if you would like to use that as one your sources.

Another great source of vitamin D is the Sun.  When you are out in the sun UV rays trigger vitamin D production in your skin.  Now there are several factors that will affect the amount of vitamin D your skin will produce based on your geography.  For those of us in the sunshine state it is much easier to attain the 10-15 minutes needed for ample vitamin D production.  For those of you in a colder climate or a city where there may be more pollution the time may be a little longer.  If you are wearing a sunscreen over an SPF of 8 it will block the UV rays from triggering the production of vitamin D.

If you are not a fan of eating fish or being out in the sun you can always find vitamin D supplements. With some simple research on the internet you can find the Recommended Daily Intake for vitamin D.

Periodic testing by your doctor will help you ensure that your vitamin D levels are consistent to where they need to be.

With encouraging findings from researchers and a relatively simple way to acquire the necessary vitamin D that your body need we hope that you attain these levels required and give yourself the best chance for combating the effects of aging in your eyes.
