What Are The Possible Disadvantages Of Too Much Caffeine
In my opinion, the main disadvantage of too much caffeine revolves around emotional intelligence . This is because caffeine activates the release of adrenaline. When adrenaline is released, increased stimulation of the brain occurs. This can cause the emotions to overrule normal behavior. In a nutshell, too much caffeine can cloud the decision making process. Other disadvantages may include:
- Sleep problems
- Shallow breathing
- Irritability
- Anxiety
Most of these disadvantages boil down to the sensitivity of the individual. In other words, some people just dont vibe with caffeine. Others cant vibe without it.
Medications That Cause Dry Eyes
There are numerous different medications that can either increase the dryness of your eyes or cause your eyes to dry out altogether. People respond differently to medicationsone person might experience no side effects, and another taking the same medication will have serious complications.
Here is a look at some medications that have been reported to cause dry eyes:
Caffeine For Dry Eye: Perspective
The idea could have merit but needs much more research, says Pedram Hamrah, MD, attending physician and surgeon at Massachusetts Eye and Ear and assistant professor of ophthalmology at Harvard Medical School.
He reviewed the findings but did not take part in the study.
“All they are showing is in a normal person who doesn’t have dry eye, if you give them caffeine they have some increase in tear production right after,” he says. It’s not certain if the effect lasts, Hamrah says.
Most who have dry eye also have a high rate of tear evaporation, he says. The caffeine research doesn’t address that.
Hamrah reports serving as a consultant for ReVision Optics, Allergan, Alcon, and Fovea Pharmaceuticals.
“It is logical that caffeine might stimulate tear production in many individuals,” says Marguerite McDonald, MD, an ophthalmologist in Lynbrook, N.Y., and a clinical professor of ophthalmology at NYU Langone Medical Center. She also reviewed the findings.
The increased tear production is linked to certain genetic markers, she says. This explains why some people have a reaction to caffeine and others have little response. The research “may lead us to new medical therapies for dry eye,” says McDonald, who is also an adjunct clinical professor of ophthalmology at Tulane University Health Sciences Center in New Orleans.
McDonald reports consultant work for Allergan, Alcon, Bausch + Lomb, and Abbott.

How Does Caffeine Affect The Eyes
A recent study shows that people who consume caffeine produce more tears compared to those who don’t.
International Coffee Day 2018 starts with a strong cup of joe just like most other days of the year . My preferred caffeine boost can come in the form of a latte, a shot of espresso , warm or cold brew, even a cappuccino, a macchiato, or a flat white. The thought of coffee gets me out of bed in the morning, its just what I need to get going and I look forward to it every day. You get it, right?
So for a brief history lesson The popularity of coffee in the USA has come in waves. The first wave was the old-fashion morning coffee grinds like Folgers, Maxwell House, and Sanka . The first wave is pretty much over and done with . The second wave includes popular coffeehouse chains like Starbucks, Dunkin Donuts, Pret a Manger, etc. The second wave is still going strong, and probably will be for quite some time.
The third wave is the craft coffee revolution, which has been sparked by specialty coffee shops all over the country . Currently, the third wave is riding unprecedented popularity. Currently, the third wave is also doing a number on my wallet . Some people claim were experiencing a fourth wave because of advancements in roasting methods, brewing methods, and DIY methods. But Im still riding the third wave, especially since Cafe Grumpy opened in Grand Central Station.
Is Drinking Tea Good For Your Eyes
Drinking tea can be beneficial for your eyes, however this will depend on the type of tea you are drinking. For example, green tea offers incredible benefits including antioxidants and nutrients. In normal tea, however, its important to note that tea leaves contain more caffeine than coffee. But we consume less caffeine in tea as the caffeine content is usually extracted instantly while brewing. Its important to remember that caffeine can be found in many things besides tea and coffee, and that we must be careful not to overconsume it.

Caffeine And Your Eyes
Caffeineits what many of us start our mornings off with and, for many more, how we recharge our afternoons. Caffeinated beverages are a delicious way of boosting your energy and stimulating the brain so that youre awake, alert, and ready to seize the day. But can they be bad for your eyes?
To some extent, caffeine can benefit your eyesight. It has the potential to alleviate dry eyes, protect eyes against retinal damage, and more. But with overconsumption, comes negative effects.
Michigan Eye Institute is here to discuss the correlations between caffeine and vision and how much caffeine is the right amount. Read more to find out.
So How Much Caffeine Should You Drink
With all things considereddont worry! Your favorite morning pick-me-up doesnt have to go away.
Everything consumed in moderation is okay, and caffeine is no different. As far as how much you should consume, its hard to give a definitive answer, for it may vary from person to person.
However, the FDA has cited that 400 milligrams of caffeine a day is generally not associated with dangerous side effects. However, certain people may be more sensitive to caffeine than others. We suggest you consult with Michigan Eye institute or your PCP if you have questions about your intake.
That equals out to roughly four cups of brewed coffee or two energy shot drinks. Please keep in mind that the caffeine amount in beverages varies widely, especially among energy drinks.

Foods That Cause Disease
Filling your diet with foods that are nutritionally deficient and have high saturated fats is the quickest way to derail the balance of your body. If your body is busy fighting the damage caused from foods like ice cream, hamburgers, and pepperoni pizza after meal times, then you will lack energy, feel depressed, and want to sleep due to all energy being exerted to the meal you just had.
DONT WORRY, though. If youve eaten terribly your whole life, it is not too late. Choose to turn the switch now to a healthier lifestyle and accept the challenges that come with it. Start eating healthy today and your body will heal your past wrongdoings, because of its incredible ability to heal.
This will be a tough challenge, so I always recommend a cheat day. This is 12 hours in which you can eat anything and everything you have been craving that whole week. Make it count, but then go back to the healthy, feel better foods for the other 156 hours in a week.
Try this out for a test For a full day make a green smoothie for breakfast, lunch, and dinner. Write down the answers to the following questions:
Did I feel tired all day?
Did I feel like I needed an afternoon nap?
Was I unmotivated to do my most important work at my job?
Did I poop?
Did I feel like drinking more caffeine to stay awake?
Did I experience cramping?
How did I feel the day after I ate all this?
Caffeine: How Much Should You Drink
Its hard to give a definitive answer, as coffees caffeine content varies a lot: ranging from 50 to over 400mg per cup. A regular cup you make at home will provide around 95mg of caffeine, while a Starbucks grande Americano packs over 300mg. NHS research, spanning across 200 studies, found that drinking 3 cups of coffee a day could be beneficial for most people. Moderate coffee consumption was linked to lower risks of diabetes, liver disease, dementia and even some types of cancer.
Raw coffee beans contain chlorogenic acid , an antioxidant that helps to reduce blood pressure and improve circulation. CGA can help to protect the body from a condition called hypoxia, caused by a lack of oxygen. Your retina is particularly vulnerable to hypoxia, so drinking coffee could help prevent any damage to your eyes and vision.
Tests using CGA in its purest form have shown that it can prevent deterioration of the retina, but there is yet to be solid proof that drinking coffee can help with this.
However, consistently going above the recommended amount could impact your health and vision, as it puts you in higher risk of developing chronic conditions such as glaucoma.

Alcohol And Chronic Dry Eye
Some studies have shown that light to moderate alcohol use may have some health benefits. Like other substances, weighing the risks and benefits may be confusing.1
No doubt, drinking alcohol can have serious consequences for the health and well-being of the person drinking, as well as those around them. In 2019, more than 14 million adults over the age of 18 had alcohol use disorder , costing the United States economy more than 249 billion dollars.2
It turns out that you do not need to have AUD to have the negative outcomes of alcohol as it relates to dry eye. Your evening cocktail after work may be causing or worsening your dry eye symptoms. Drinking alcohol causes changes to both your eyes and the tears, including:3-7
- Abnormalities in the makeup of tears
- Formation of cataracts with heavy drinking A cataract is a clouding of the lens inside the eye, which is usually clear at birth. The lens helps to focus light onto the retina, located at the back of your eye. Cataracts develop slowly over time and usually do not cause noticeable vision changes until age 60 or older.
Is Caffeine More Helpful Or Harmful To People With Dry Eyes
It was once thought that caffeine might contribute to dry eyes because its a diuretic. That means it causes the body to expel more fluids through urine.
Studies have failed to link caffeine to dry eyes. In fact, several small studies in healthy people suggest that caffeine may stimulate tear production.
For example, one double-blind 2012 study of 78 people found that those who took caffeine tablets had more tears than those who received a placebo tablet. Another 2014 study of 41 people came to a similar conclusion.
While these findings are promising, its uncertain if they apply to the general population. Future studies need to test whether caffeine produces tears in people who actually have dry eye disease , are older, or who have other health conditions.
Other research is less convincing. In a study published in 2018, researchers looked at the link between coffee consumption and DED. They found that the prevalence of DED decreased as coffee consumption increased.
People who drank more than three cups of coffee per day had the lowest rates of DED, at 6.3 percent. Thats compared to 8.8 percent of people who drank one to two cups per day and 9.2 percent of people who had less than a cup of coffee per day.
This increased risk for DED disappeared after researchers added other risk factors for DED to their analyses, such as the sex of participants.

Coffee Can Be Beneficial When Applied Topically
If you’d rather quit drinking coffee altogether than drink it black, we don’t blame you. It can be hard to adjust to the bitter taste of coffee when you’re used to all the sweeteners and creamers. But that doesn’t mean you have to forgo all the skin-loving benefits of the morning beverage. Goldenberg says topical products that contain caffeine also have anti-inflammatory and antioxidant properties. Although the effects are short-term, Goldenberg says the caffeine in topical products can decrease the appearance of cellulite by dehydrating the tissue. Bowe adds that coffee grounds also work to reduce swelling and puffiness, which is why you’ll commonly find this ingredient in eye creams and treatments.
The takeaway: When consumed correctly, coffee is good for your skin. But if you’re one of those who can’t bear the taste of plain coffee, shop some coffee-infused products below to make caffeine-free mornings a little more bearable.

Foods That Cause Dry Eyes
According to The Tear Film and Ocular Surface Societys Dry Eye Workshop from 2017, the definition of the condition commonly referred to as dry eye, is: Dry eye is a multifactorial disease of the ocular surface characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and hyperosmolarity, ocular surface inflammation and damage, and neurosensory abnormalities play etiological roles. If that sounds like a mouthful of incomprehensible doctor mumbo jumbo, it is. In short, dry eye is caused by inflammation in the body, which can cause the the eyes of a person to feel painful and dry, and appear red and inflamed, and ultimately, damage the eyeball itself, which could impair vision.
Luckily, researchers have found that the foods that a person eats have an impact on the eyes, and can either affect them negatively or positively.
Heres foods that they found that can be harmful to the eyes:
- Alcohol
- Refined sugars, which are found in sweets like cakes, candy bars, and cookies.
- Foods with artificial sweeteners like flavored drinks.
- Red meat
