Ways to maintain eye health with screens

Published

on

When we use digital devices such as phones, tablets, and computers, we are exposed to blue light. Blue light is part of the visible light spectrum and has shorter wavelengths. While exposure to natural sunlight during the day can boost mood and alertness, excessive exposure to blue light from screens in the evening can disrupt our sleep cycle.

Digital-related eye strain affects people of all ages. If you spend hours a day using digital devices, you might notice your vision blurs and your eyes feel achy and tired. Your eyes may also become dry and with tears or stings. Eye strain from the use of digital devices is not different from the symptoms you may experience when reading, writing, or doing “close work,” such as sewing for long periods.

There have been studies on blue light using cells in a dish and animals, but these experiments did not mimic the natural conditions of blue light exposure to live human eyes. So far, there is no meaningful link between blue light and damage to human retinas or age-related macular degeneration. However, the level of device usage impacts eye health.

Eyeglasses with special blue light-blocking filters claim to improve sleep, reduce digital eye strain, and prevent eye disease. However, spending money on these glasses is optional for computer use.

Blue light from computers will not lead to eye disease. While overexposure to blue light and ultraviolet rays from the sun can raise the risk of eye disease, the small amount of blue light emitted by computer screens has not been shown to harm your eyes.

Sleep can be improved without special eyeglasses. Simply decrease evening screen time and set devices to night mode to promote better sleep.

Digital eye strain is not caused by blue light. Symptoms of digital eye strain (such as dry eyes, blurry vision, and headaches) are linked to how we use our devices, not the blue light itself.

How device usage affects eye health

Experts at Rochester Optical, a United States-based optical clinic have outlined some effects of digital devices on the eyes.

Straining your eyes

Constant exposure to digital screens, such as smartphones, tablets, and computers, can lead to digital eye strain. This occurs due to the extended periods of focusing on a screen, which can cause eye fatigue, eye discomfort, and blurred vision. The repetitive movements of our eye muscles to focus on screens without proper breaks can result in strain and discomfort.

Blue light exposure

Smartphones, tablets, computers, and other devices with screens emit blue light, which often disrupts our sleep patterns and negatively impacts our health. Prolonged exposure to blue light may contribute to retinal damage, increasing the risk of age-related macular degeneration.

Reduced blinking and dry eyes

When using digital devices, we tend to blink less frequently, resulting in dry and irritated eyes. Continuous staring at screens reduces the natural rhythm of blinking, leading to dry eye symptoms.

Increased myopia rates

Children and young adults are especially vulnerable to myopia (nearsightedness) due to excessive screen time. Regular eye examinations conducted by eye care professionals can help detect and manage myopia early on. By monitoring your child’s screen time and scheduling routine eye exams, you can actively protect their eye health and reduce the risk of myopia progression.

Eye fatigue and headaches

Staring at screens for prolonged periods can strain the eye muscles, leading to eye fatigue and headaches. This discomfort may negatively impact productivity and overall well-being.

Tips to prevent digital-related eye strain

Blink frequently

Humans normally blink about 15 times per minute. However, studies show that we only blink about five to seven times per minute while using computers and other digital screen devices. Blinking is the eye’s way of getting the moisture it needs on its surface. Make a conscious effort to blink as often as possible. Consider placing a sticky note on your computer screen to remind you to blink regularly.

Follow the 20-20-20 rule

Every 20 minutes, look away from your screen and focus on an object at least 20 feet away for 20 seconds. This gives your eyes a chance to reset and replenish themselves.

Use artificial tears

If your eyes feel dry, use artificial tears to refresh them.

Adjust your screen settings

Set your devices to night or dark mode in the evening. This reduces screen brightness and minimises the impact of warm colours on your circadian rhythm.

Take breaks

Frequent breaks help reduce eye strain. Consider using a humidifier if you are often in a dry, warm room.

Adjust your position at the computer

When using a computer, you should be sitting about 25 inches (right about at arm’s length) from the screen.

Proper ergonomics play a vital role in preventing eye-related discomfort. Adjusting the height and position of the screen, as well as using ergonomic accessories like monitor stands and chairs, can help maintain a healthy posture and reduce eye strain.

By creating a comfortable and ergonomic workspace, individuals can decrease the risk of eye strain, preventing potential long-term complications. Investing in ergonomic solutions such as adjustable monitor stands, ergonomic keyboards, and chairs with proper lumbar support can significantly improve your overall comfort and reduce the strain on your eyes and neck.

Consult physician

Regular visits to an eye doctor can help identify and address these issues promptly, ensuring optimal eye health, as well as personalised care and advice tailored to your specific needs, reducing the strain on your eyes.

Eye care professionals at Rochester Optical recommended using blue light filtering glasses or screen protectors as a preventive measure. These protective measures help reduce the harmful effects of blue light and promote healthier eyesight. By wearing blue light glasses or using screen protectors, you can minimize the effect of blue light and protect your long-term eye health.

Remember, protecting your eyes involves more than just worrying about blue light. Proper eye care includes maintaining a healthy lifestyle, regular eye examinations, and practising good screen habits.

By following these tips, you can keep your eyes comfortable and healthy while using digital devices.

7 health benefits of eating seaweed

Published

on

By

Seaweed, also known as kelp, nori, or marine algae, comes in a variety of shapes, sizes, and colours.

Each variety offers its distinct taste and texture. Seaweed is surprisingly versatile and can be enjoyed in a multitude of ways.

Here are 7 amazing reasons to consider adding a touch of the ocean to your plate:

Seaweed is a nutritional goldmine, brimming with essential vitamins and minerals that your body needs to thrive. It’s an excellent source of iodine, a vital mineral for healthy thyroid function. Just a small amount of seaweed can meet your daily recommended intake of iodine, helping to regulate your metabolism, energy levels, and brain function.

Seaweed is also a good source of vitamins A, C, E, and K, all essential for maintaining a healthy immune system and promoting cell growth and repair. Seaweed is also a natural source of magnesium, essential for regulating blood pressure and muscle function, as well as iron, which helps transport oxygen throughout your body.

It contains calcium, crucial for strong bones and teeth, and potassium, which helps maintain healthy blood pressure.

The human gut is a complex ecosystem teeming with trillions of bacteria, both good and bad. A healthy balance of these microbes is crucial for health and digestion. Seaweed is a prebiotic, meaning it provides nourishment for the good bacteria in your gut. These friendly bacteria help with digestion, and nutrient absorption, and even play a role in immune function.

By feeding these good bacteria, seaweed helps to create a thriving gut environment that keeps you healthy. Studies have shown that a balanced gut microbiome can help reduce the risk of digestive issues like constipation and irritable bowel syndrome, as well as strengthen your immune system against harmful pathogens.

If you’re looking for a natural way to manage your weight, seaweed might be your new best friend. Seaweed contains a type of fibre called alginate, which forms a gel-like substance in your stomach. This gel helps you feel fuller for longer, promoting satiety and reducing cravings. This, in turn, can lead to a decrease in overall calorie intake and support weight management efforts.

In addition to its fibre content, seaweed is naturally low in calories and fat, making it a guilt-free way to add variety and nutrients to your meals.

Heart disease remains a leading cause of death worldwide. The good news is that seaweed might offer some protection for your heart. Seaweed contains healthy fats, including omega-3 fatty acids, which have been shown to promote heart health by reducing inflammation, lowering bad cholesterol levels, and improving blood pressure.

Seaweed may also help to prevent blood clots, which can block arteries and lead to heart attacks and strokes. Furthermore, its rich supply of antioxidants helps fight free radicals that can damage blood vessels and contribute to heart disease.

For people with diabetes, managing blood sugar levels is crucial. Seaweed might offer some unique benefits in this regard. Studies suggest that certain types of seaweed, like wakame and fucoidan, may help regulate blood sugar levels. These seaweeds may slow down the absorption of carbohydrates in the gut, preventing blood sugar spikes after meals.

Additionally, seaweed may improve insulin sensitivity, allowing your body to utilise insulin more effectively and keep blood sugar levels under control.

Symptoms, risk factors, treatment — what to know about throat cancer

Published

on

By

On Thursday, Ogbonnaya Onu, a former minister of science and technology in the Muhammadu Buhari administration, died aged 72.

Reports suggest that Onu, who was the first civilian governor of Abia state, grappled with throat cancer before his demise.

If you came across the news, you may have wondered for a quick minute about throat cancer and maybe imagined how the symptoms would physically manifest. Perhaps you imagined a lesion or even a swollen neck.

What is throat cancer?

It refers to a type of cancer that develops in the throat, also known as the pharynx.

The human throat is a muscular tube that begins behind the nose and ends in the neck. The voice box sits below the throat and contains the vocal cords.

The two types of throat cancer are pharyngeal and laryngeal cancers, also known as cancer of the pharynx and the larynx.

What are the symptoms of throat cancer?

Symptoms of throat cancer include persistent cough, sore throat, a lump in the throat that does not heal, changes in voice, such as hoarseness or not speaking clearly, difficulty swallowing, ear pain, and sudden weight loss.

What causes throat cancer?

Throat cancer occurs when cells in the throat develop genetic mutations that cause them to grow uncontrollably. The continuous growth kills the normal cells. Then, the accumulating cells can form a tumour in the throat.

It is not clear what causes the mutation that leads to throat cancer. There are, however, factors that can increase the risk of throat cancer.

These risk factors include a family history of cancer, smoking and chewing tobacco, excessive alcohol intake, viral infections including human papillomavirus (HPV) and Epstein-Barr virus, and a diet lacking in fruits and vegetables.

How can one reduce the risk of having throat cancer?

While there are no scientifically proven ways to prevent throat cancer, there are ways to reduce its risk such as eating a diet rich in fruits and vegetables, drinking alcohol in moderation, avoiding smoking, and protecting oneself from HPV.

How is throat cancer diagnosed?

Throat cancer diagnosis involves a few steps. A physical examination will be performed in which a doctor will examine the mouth and throat.

The examination also involves a series of blood tests, while an endoscopy will be carried out.

An endoscopy is when a thin tube with a light on its end is inserted through the nose to look for abnormalities in the throat.

A chest x-ray and computerised tomography (CT) scan may also be carried out.

How is throat cancer treated?

Treatment of throat cancer will depend on the size of the tumour, whether it has spread all over the place, and the overall health of the patient.

The doctor will first need to find out what stage of cancer the individual has, that is, how far it has spread. This helps to determine the best treatment options.

Surgery may be recommended depending on the tumour size and chemotherapy may also be required.
