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.

5 symptoms and causes of infertility in men

Published

By

Trying to conceive a child can be an exciting time, filled with hope and anticipation. But for some couples, it can also be a frustrating journey.

If you’ve been trying to get pregnant for a year without success, you and your partner might be facing infertility.

Infertility is a common condition affecting about 1 in 7 couples and it can affect both men and women. We’ll be focusing on male infertility, what to look out for, and the reasons behind it.

Let’s clear something up first: there often aren’t any obvious signs of male infertility. The main indicator is simply the inability to conceive a child after a year of trying. However, there can be some underlying issues that might cause problems. By understanding these, you can have a more open conversation with your doctor and explore potential solutions.

This can include problems ejaculating, low semen volume, erectile dysfunction (trouble getting or keeping an erection), or reduced sex drive. These issues can sometimes be symptoms of hormonal imbalances or other conditions affecting fertility.

Pain, swelling, or a lump in the testicle area can be a red flag.

Healthy sperm production relies on the proper functioning of the testicles, so any abnormalities there might need to be checked by a doctor.

Certain medical conditions like undescended testicles (when the testicles don’t move down into the scrotum before birth), infections (including sexually transmitted infections), or surgeries like vasectomy (a procedure for permanent birth control) can impact sperm production or delivery.

Habits like smoking, heavy alcohol use, and recreational drugs can all affect sperm quality and count.

Why you’re not losing weight even though you work out

Published

By

Working out is usually seen as the go-to solution for weight loss. You put in the effort, sweat through the workouts, and expect the scale to show your hard-earned results.

However, many find themselves frustrated when the weight doesn’t come off as expected. This common issue can be disheartening, but understanding why you’re not losing weight despite exercising can empower you to make the necessary adjustments and continue your fitness journey with confidence.

Let’s explore the key reasons why your workout might not be reflecting on the scale.

One of the most positive reasons for not seeing a drop in weight is muscle gain. Muscle is denser than fat and takes up less space in your body. Therefore, as you lose fat and gain muscle, your overall weight might not change, but your body composition is improving. You might notice your clothes fitting better or see more muscle definition​​.

Hydration is crucial for weight loss. Water helps suppress appetite, boosts metabolism, and aids in digestion. When you’re dehydrated, your body might retain water, making you feel heavier. Aim to drink at least half your body weight in ounces of water daily, especially if you’re increasing your fibre intake​.

3. Eating more than you burn

Exercise can increase your appetite, and without mindful eating, you might consume more calories than you burn. Even healthy foods can contribute to weight gain if eaten in large quantities. Tracking your calorie intake can help ensure you’re in a calorie deficit, which is necessary for weight loss​​.

Non-exercise activity thermogenesis (NEAT) plays a significant role in weight management. NEAT includes all the movements you do outside of structured exercises, such as walking, cleaning, and fidgeting. If your workouts leave you too exhausted to move much for the rest of the day, your overall calorie burn might decrease. Incorporating more daily movement can boost your NEAT and aid in weight loss​.

Sleep is essential for regulating hormones that control hunger and metabolism. Inadequate sleep can increase levels of ghrelin, the hunger hormone, and decrease levels of leptin, the hormone that makes you feel full. This imbalance can lead to increased appetite and weight gain. Aim for seven to nine hours of sleep per night to support your weight loss efforts​.

Chronic stress can lead to elevated levels of cortisol, a hormone that promotes fat storage, particularly around the abdomen. Additionally, certain medical conditions and medications can affect your weight. If you suspect stress or a health issue is hindering your progress, consider consulting a healthcare professional for guidance​​.

What to eat and avoid when treating malaria

Published

Malaria is a serious disease that affects millions of people around the world. It is caused by parasites transmitted to humans through the bites of infected mosquitoes.

When someone gets malaria, they often feel very sick with symptoms like high fever, chills, headache, and muscle pain. If not treated promptly, malaria can become life-threatening.

However, with proper medical care and attention to diet, patients can recover.

Malaria is transmitted through the bite of a female Anopheles mosquito infected with Plasmodium parasites.

When this mosquito bites a person, the parasites enter the bloodstream and travel to the liver, where they multiply. After leaving the liver, they infect red blood cells, causing the symptoms of malaria.

The primary treatment for malaria is antimalarial medication prescribed by a doctor. The type of medication and length of treatment depend on the type of malaria parasite and the severity of the disease. Early diagnosis and treatment prevent complications.

Patients should follow their doctor’s instructions carefully and complete the full course of medication even if they start feeling better.

Proper nutrition plays a vital role in the recovery from malaria. Here are some foods that can help:

  • Fruits and vegetables: Fresh fruits and vegetables are rich in vitamins and minerals that boost the immune system. Oranges, apples, carrots, and leafy greens are excellent choices.
  • High-protein foods: Protein is essential for healing and rebuilding body tissues. Include lean meats, fish, eggs, beans, and nuts in your diet.
  • Whole grains: Whole grains like brown rice, oats, and whole wheat bread provide necessary energy and fibre, aiding digestion and overall health.
  • Hydration: Drinking plenty of fluids is crucial. Water, fresh fruit juices, and coconut water help keep the body hydrated and flush out toxins.
  • Soups and broths: Light soups and broths are easy to digest and can be nutritious. Chicken soup, in particular, is beneficial.

Certain foods can hinder recovery from malaria and should be avoided:

  • Fatty and fried foods: These can be difficult to digest and may cause nausea or discomfort. Avoid fried snacks, heavy sauces, and greasy meals.
  • Processed foods: Processed and packaged foods often contain unhealthy fats, sugars, and preservatives that can weaken the immune system.
  • Caffeinated drinks: Coffee, tea, and other caffeinated beverages can lead to dehydration, which is not ideal when dealing with malaria.
  • Alcohol: Alcohol can interfere with the effectiveness of antimalarial drugs and can also dehydrate the body.
  • Spicy foods: Spicy foods can irritate the stomach and should be avoided, especially if the patient is experiencing nausea or vomiting.

Malaria is a serious disease that requires prompt medical treatment and proper care. Along with taking prescribed medication, eating the right foods can significantly aid in recovery.
