How Blue Light from Devices Hurts Your Eyes

While everybody already knows that too much exposure to sunlight and air pollution can affect us and it’s sometimes just better to stay indoors, not many people really understand that the same indoor environment can also be damaging to the skin and eyes.

This is because of blue light, which more studies are showing to be responsible for creating free radicals that can harm both skin and eyes much like ultraviolet light.

And because nearly all of our workdays are spent exposed to signficant amounts of it, the effects can compound and result in significant damage over time. But what exactly is blue light, and how exactly can it damage you?

Photodamage and Blue Light

Blue light is the light on one end of the visible spectrum that has the shortest wavelength, with yellow and red lights on the other end of that spectrum and having the longest wavelengths.

However, blue light has a really high energy, giving it the name “high-energy visible” light. This high-energy light usually comes from sunlight, but it can also come from the screens of different devices, such as computers and smartphones, as well as fluorescent lights commonly used in offices.

Negative Effects of Blue Light

While our eyes are capable of blocking out ultraviolet light, it’s not as good at blocking blue light. This means that it can have some pretty bad effects after exposure to significant amounts over time, such as the following:

  • It increases the risk of eye strain
  • It contributes to macular and retinal degeneration
  • It can cause uneven skin pigmentation

Reducing Blue Light Exposure

Keep in mind that not all blue light is bad, however – more studies are also showing that a certain amount of it is essential for good health. In fact, in the right levels, it can boost alertness as well as help with memory and cognitive functions.

What makes it bad is too much exposure, so the best thing you can do is to limit your exposure when you can in order to reduce the harmful effects that it can have. You can limit your exposure to blue light by using two things:

  • Using blue light filters on your devices – The good news is that there are now more devices that include a feature that filters the blue light emitted from the screen, especially in the case of smartphones and tablets. You can even have physical filters installed for your phones and computers installed for this purpose.
  • Investing in protective eyewear – Special pairs of glasses dedicated for use around computers have yellow lenses in order to decrease the wavelength of blue light, and they are usually available without a specific eyeglass prescription.

Your Guide to Eating Healthily During the Ramadan Season

It’s the time of the year where our Muslim brothers and sisters solemnly follow Ramadan. With roughly more than 15 percent of Singapore citizens practicing Islamic faith, the city-state celebrates the holy month of fasting along with the other countries in Southeast Asia.

When done right, it is believed that the celebration of Ramadan manifolds spiritual blessings together with tangible physical benefits to its followers. For instance, eating only healthy food choices while fasting resets the metabolism, sheds a good few pounds off the body, as well as lowers one’s cholesterol count.

Healthy eating during Ramadan can be quite a challenge but it does not mean rigidly following a boring, bland diet. Fasting is not a reason to eat with abandon, either, nor should it be according to Sunnah or the prophetic Islamic traditions. This article will present ways in which you can eat healthily during the holy month of fasting.

• Stagger hydration
During the summer season, dehydration can be the toughest part to overcome when fasting. Drinking lots of water is not much of a good plan as well since it would cost you multiple visits to the loo in the midst of prayer. Hence is why staggering your hydration through the night is a good way to keep yourself hydrated when you fast during the day. Avoid too much sun exposure to lessen moisture loss by sweating and limit your coffee and tea intake, as they only dehydrate the body further.

• Avoid sugar
As much as we crave sweet treats every now and then, avoid food that are high in sugar during your fast. Sweet treats only gives you empty calories without necessary nutritional benefits. Most of the time, it is also the culprit behind overeating during the Ramadan season. Substitute your sugar-filled snacks for fresh fruits instead.

• Incorporate fiber in your diet
With your irregular meal times and no morning dose of caffeine, constipation becomes one of the many issues people suffer during Ramadan. To prevent this, incorporate fiber in your meal plan to keep your gut moving. Fresh fruit, greens, and wheat-based food helps in boosting your fiber intake and promotes normal bowel movement.

• Use less oil
Hit the pause button on consuming greasy, oily food. Allocate fried foods only for very special occasions and resort to baking or grilling your meal, if possible. This kind of cooking preparation not only uses a lot less oil but they also provide the body with the nutrients that we need.

• Practice moderation
In line with the spirit of the fasting season, do not indulge yourself daily and limit your guilty pleasures to a once a week treat. Practice moderation. You are free to indulge in your Ramadan favorites like pakoras at iftar, but lessen unhealthy food intake to bite-size portions. That way, you can savor them longer instead of wolfing down platefuls of it.
