Tunnel vision is usually used to describe someone with a narrow point of view. Taken literally however, it can describe the type of vision that results with untreated glaucoma. With eye injury prevention month coming to a close next week, it seemed right to talk about ways to prevent glaucoma. This is because those with eye injury are at a higher risk of developing this condition. A recent study has found that turmeric, a natural spice, may be the golden ticket to potentially prevent glaucoma and preserve eye health.
What is glaucoma?
Glaucoma is not just one eye condition. However, it is a group of eye diseases that damage the optic nerve and can cause vision loss and blindness. Research suggests that eye pressure is a major cause of the vision loss caused by glaucoma.
Another risk factor of optic nerve damage, and in turn, glaucoma, is high blood pressure. Even though it may seem unrelated to eat healthy to keep your eye healthy, there are blood vessels in your eye that get their blood flow from the heart. When high blood pressure constricts blood flow, it can cause pressure in the eye. In turn, this can cause vision issues.
Turmeric and glaucoma prevention
When you consider the heart health component of vision health, then turmeric as a preventive treatment makes sense. This is because turmeric is a natural anti-inflammatory agent. Since heart health issues stem from increased inflammation, then turmeric may very well benefit such conditions.
Turmeric is a root plant grown throughout Asia and Central America. It is an important part of ayurvedic medicine as a treatment for inflammatory-related conditions like pain, fatigue, arthritis, and breathing problems. Curcumin is the active ingredient in turmeric due to its antioxidant properties which help prevent cell damage that can lead to chronic disease. Although it is consumed as a spice in foods, turmeric can also be consumed in tablets, capsules, tea, or extracts.
A recent study shows that eye drops containing curcumin may help treat or prevent glaucoma. A rat study found that twice-daily use of the curcumin drops for three weeks helped reduce retinal ganglion cell loss. In other words, the eye drops helped preserve the cells in charge of delivering visual information from the eye to the brain. This study suggests that curcumin eye drops may be a treatment or preventive treatment for those at risk for glaucoma upon further study.
How to help eye health
Besides curcumin, there are things you can do today to help improve eye health.
- Eat right by consuming lots of antioxidant rich fruits and vegetables every day. This will help reduce inflammation in the body and in turn keep your eyes healthy.
- Keep your weight in a healthy range since obesity can increase risk of diabetes, which can in turn increase risk of vision loss.
- Protect your eyes with sunglasses or other eyewear like goggles or safety glasses. This is because you can prevent eye injury from sports or work accidents if your eyes are protected. Also, shielding your eyes from the UV rays of the sun can reduce eye damage.
- Quit smoking or don’t start since it can constrict blood vessels. This can in turn negatively affect blood vessel health of the eye and increase risk of eye diseases.
- Reduce screen time each day since looking at a computer, television, or phone screen too much without taking a break can put strain on the eyes. Therefore, experts suggest taking a break from the screen every 20 minutes by looking 20 feet in front of you for 20 seconds.
- Take a eye health supplement daily like Ocutain by Vita Sciences. Ocutain contains antioxidants such as lutein and beta carotene that can benefit vision health.

Now you may be saying to yourself, “Another article telling me to eat vegetables.” :sigh: However, this is not just another one of “those” articles. There are more reasons to eat your veggies than you may think. Besides providing digestive-friendly fiber and antioxidants, a recent study has shown that eating a more plant-based diet can actually lower your heart and diabetes health numbers.
Heart disease is the leading cause of death for men and women in the United States. It accounts for one in four deaths each year. However, yo can prevent heart disease by changing some lifestyle factors to lower your risk. Risk factors of heart disease include poor diet, physical inactivity, being overweight or obese, being a smoker, and having diabetes. Fortunately, by working to change a few things in your daily routine, you can lower your risk of heart disease. Here are the top five things you can do today to lower your risk of heart disease.
When you don’t get enough sleep, it can affect your whole day. You may move slower, have less energy, your mind may have a hard time learning or remembering things, and you may be more easily stressed and irritated. In turn, these factors can affect your productivity during the day and the way you get along with others. Therefore, it is super important to get enough rest at night. And just when you thought that you were reaching your health goals, a new report states that eight hours a night of rest may not be enough.
Sleep. Work. Eat. Repeat. Does that sound like your day, or something like it? Sleep is often set aside as just something that a person does at the end of the day. It is often overlooked as a very important part of optimal health. A recent study found that it is so important in fact, that not getting enough sleep may increase your risk for mental health disorders.
With ever-increasing demands in our work schedules and family obligations as well as financial stress and personal stresses it is no surprise that anxiety is on the rise. A recent report shows that from last year, more Americans say they are more anxious than ever.
It’s Friday night and the weekend is just beginning. After a long week of work, you may be thinking about that glass of wine or pint of beer to help you relax. In moderation, there is nothing wrong with a few drinks on the weekend. However, a recent study has found that drinking more than the suggested amount each week can shorten your life.
Nearly half of all Americans have high blood pressure, or hypertension. Having hypertension can put you at increased risk for heart disease and stroke, which are two of the top five leading causes of death in the United States. Therefore, it is important that if you have high blood pressure that you should work to be more heart healthy to prevent chronic disease. This usually includes eating a heart healthy diet and exercising. However, a recent survey shows that exercise is the last thing people want to do to try and lower their blood pressure.
When you take a medicine over the counter, you likely focus mostly on the benefits it can provide you. However, it’s possible to experience some harmful health effects from use of over-the-counter medicines. A recent study has found that some common painkillers used by those with arthritis may cause high blood pressure.
