You need a cup of coffee, and it’s early in the morning. Coffee is your source of quick energy to start the day, whether you prepare it yourself or stop by a drive-through for a tasty combination.
It might be prudent to examine how coffee affects your body, particularly your vision, before your cup overflows.
What effect does coffee have on my body?
Caffeine, an ingredient in coffee, somewhat stimulates your central nervous system. The caffeine in coffee, as the name says, increases alertness and, depending on your intake and tolerance levels, can have impacts on your mood that range from intense focus to jitteriness.
Late-night drivers, college students, third-shift workers, and anyone who needs an additional boost can benefit from caffeine.
Are there any drawsbacks to coffee?
There are some drawbacks to coffee despite its benefits. Coffee use might disrupt your circadian cycle and cause restlessness. In addition, if ingested too soon or with a poor diet, it might cause upset tummies.
The rise in blood pressure, which can also have extra side effects, is likely coffee’s most detrimental consequence. An ophthalmologist with CEENTA from our offices in Matthews and Monroe shares her perspective on what occurs when sugar is added to coffee.
Everything we ingest, even supplements, may have an impact on several organs, including our eyes.
Caffeine consumption frequently results in headaches, but the high sugar content of many coffee drinks can also lead to diabetes and high blood pressure problems.
The Effects of Caffeine on Your Eyes
As much as we enjoy the adrenaline boost that caffeine provides, there are a number of ways that it can harm your eyes.
- Risks of Glaucoma Increasing
A recent study found that drinking three or more cups of coffee per day increases the risk of getting several types of glaucoma. The study was unable to draw the conclusion that alternative caffeine sources had the same effects.
Should you stop drinking your cup of coffee? Actually, no. A cup or two a day won’t be enough to raise your risk, but it’s still important to be conscious of your intake.
- Hazy vision
Blurred vision typically results from a reduction or spike in blood sugar, albeit this is only true in extreme circumstances of probable caffeine overdose.
It’s critical to keep a close eye on any unexpected changes in your energy levels because they can be a sign of another health problem.
Vision blurring can also result from caffeine overdoses, which can happen if you drink more than 1,000 mg of caffeine in a 24-hour period. You should speak with a medical expert right away if you think you might have taken too much.
- Angry Eyes
Have you ever had twitching eyes after consuming a lot of coffee? It undoubtedly results from ingesting too much caffeine. By avoiding too much coffee, you can prevent the twitch.
- Anxiety
It should come as no surprise that almost half of us (49%) say we can’t begin the day without a cup of tea or coffee, but nearly one in five of us (18%) say caffeine makes us anxious.
The ‘fight or flight’ hormone adrenaline, which is linked to enhanced energy, is released when caffeine is consumed.
These effects are amplified in cases of caffeine overdose and can make us feel tense, agitated, and jittery. Stress levels have been observed to rise with both increased and low doses.
- Insomnia
The fact that so many of us consume coffee to stay awake also means that it can be challenging to have a good night’s sleep, with a third (33%) of people reporting that caffeine makes it hard for them to fall asleep.
Caffeine can persist in your system for up to nine hours, so it’s vital to be mindful of when you consume it to avoid having an adverse effect on your ability to sleep or recuperate.
When you have dry eyes as a sign of insomnia, it’s crucial to moisten them with eye drops and, if you can, avoid using contact lenses until the condition goes away.
- Headaches
Intriguingly, more than one in five of our respondents (22%) said that caffeine gives them a headache, while more than two fifths (43%) reported that it doesn’t.
Since caffeine is present in over-the-counter pain relievers, it can actually assist reduce inflammation, which leads to a reduction in pain.
Unfortunately, the same thing that makes caffeine so good at relieving headaches can also make them worse.
When you quit taking coffee, the blood vessels around your brain reopen and your pain returns because caffeine constricts those blood vessels.
Conclusion
Caffeine intake for an adult should not exceed 400 milligrammes (mg) per day, which is equal to around four cups of coffee.
