Ways to prevent cataracts formation

Astronauts receive higher daily dose of radiation, especially on a long mission such as the future Mars flight. As a result, cataracts may occur more frequently in these professionals. Currently, NASA and the National Eye Institute have been cooperating in developing a non-invasive instrument that can be used to detect very early signs of cataracts and monitor any progression.

The Alpha crystalline proteins in the lens are thought to help the lens maintain its refractive index, which allows the lens to focus light on the retina and offer clear vision. Oxidative stress may cause some proteins to break down in the lens, resulting in damaged proteins. Once these damaged proteins and other damaged cellular substances are crossly linked, they can lead to large clumps and form opacity in the lens. This opacity can gradually interfere the eyesight when they grow large enough and become cataracts.

This new instrument is supposed to evaluate the function of Alpha crystalline proteins and measure their levels as well as changes. Originally developed for space program, this measurement method can now be used to detect early signs of protein damage caused by oxidative stress. Age-related cataract, diabetes, and some neurological diseases are closed associated with oxidative stress.

Oxidative stress can be caused by UV radiation, drugs, chemicals, smoking, dietary components as well as other environmental factors. Alpha crystalline proteins in normal level can prevent these damage proteins from aggregating into clumps. However, Alpha crystalline level will be lowered due to natural aging. As a result, cataracts may develop.

As mentioned before, oxidative stress is the original cause in the lens of cataract formation. Currently, antioxidants are widely accepted to prevent cataracts, although their capacity is also unclear. In detail, lutein and zeaxanthin are two of the antioxidants that can reduce the incidence of cataract formation. A daily supplement containing antioxidants is helpful in preventing cataracts formation. These antioxidants can be gained from vegetables and fruits.

People should also control some risk factors such as smoking, obesity and eating a diet high in refined food with high sugar content. Smoking is believed to systemically decrease antioxidants in the body. Some experts also think that visible blue light can cause oxidative damage in the retina. UV protection by wearing sunglasses or UV-blocking contact lenses is also quite necessary.

How to Improve Eyesight Naturally: Expert Tips

Once the eyesight starts to become just a little blurry, what other alternative is there except visit the eye doctor for an eye exam.  Usually this visit is followed by the doctor explaining to you that it’s now time to start wearing glasses or contact lens because that is the only way your eyesight will improve.  How to improve your eyesight naturally is not something you are informed about at the doctor’s office.  Here are some expert tips that just might help.  

Most people are not aware that you can improve eyesight naturally.  Every time you go to the doctor for a checkup, what are they always reminding you to do in order to remain healthy?  

Get plenty of sleep:
Why is getting a good night’s sleep so important?  When you get plenty of sleep it can help keep your heart healthy, can lower your risk of cancer, reduces stress, reduces inflammation, makes you more alert, helps your memory,  may help you lose weight, can reduce your risk of depression and helps your body repair itself.  Getting at least eight hours each night is highly recommended.

Eat a healthy diet:
We all know that staying away from junk food is highly recommended but what are the benefits of eating a healthy diet?  It can help control your weight, helps slow down the process of aging, you can perform better in sports, improves your general health, reduces cholesterol and reduces the load on the liver and digestive system.  Be sure to get your daily dosage of fruits and vegetables.

Exercise daily:
Most people don’t enjoy exercising but the major benefits of including it in your daily routine can mean more energy, a stable healthy weight, better coordination  and balance, a more fulfilling sex life and an all around better quality of life.  By exercising daily you can also prevent developing coronary artery disease, stroke, diabetes, certain cancers, arthritis and osteoporosis.   Even if you just get a 30 minute walk in each day will help tremendously.  

Another good expert tip is to reduce the stress in your daily life.  You can do this also by taking more breaks during your day.  Concentrating too much on your work or studies can cause your eyes to strain which in turn will cause stress.  If at all possible, take a short break every thirty minutes if not every hour.  Just look around the room for a few minutes or get up and take a short walk.  This can really help relieve the stress from your daily life along with getting a good night’s sleep, eating a healthy diet and exercising daily.
