Let’s have a brief look at Vitamin A drops. Are they beneficial for cases of aqueous deficient or evaporative dry eyes?
What is Vitamin A?
Vitamin A has proven useful in preventing night blindness along with some skin disorders, including acne.
It also helps enhance immunity and repair of epithelial tissue, of which skin and mucous membranes are composed of.
The body is unable to utilise protein efficiently without the help of vitamin A.
As an antioxidant, it helps to protect your cells against cancer and other diseases. The carotenoid family are a class of compounds that act as precursors to forming Vitamin A.
Beta-carotenes are the most well-known carotenoids. Sweet potato, pumpkin, carrots, asparagus and apricots provide beta-carotene for the body that can then be converted to Vitamin A in the liver. In general, all yellow fruits an veges are also good sources.
Lutein, a well-known antioxidant for prevention of macula degeneration is also a member of the carotenoid family.
Animal-derived vitamin A is called retinol and found in beef and chicken liver, whole milk and ricotta cheese.
Vitamin A drops
Vitamin A eye drops have been found to help provide lubrication for dry eyes and eye drops that contain vitamin A, such as Dakrina, VivaDrops and other over the counter drops with vitamin A added are often preferred to prescription solutions for dry eyes.
Vitamin A eye drops have also been shown to provide treatment for a specific type of eye inflammation called, superior limbic keratoconjunctivitis that affects the cornea and inside of the upper eyelids.
A 2008 study found that eye drops containing Vitamin A, as retinyl palmitate, improved symptoms of blurred vision and tear film abnormalities in four weeks.
The antioxidant protective nature of vitamin A does show some efficacy for vision related problems including, dry eyes, macular degeneration and more.
As a solution for improved comfort and protection, vitamin A drops are worth working into your eye care regime.
As with all drops, medications and so forth, you should know within several weeks whether this type of eye drop proves helpful for your specific situation.
However, addressing symptoms should be just one of the measures used to address your dry eye issue.
