What Causes Eye Fatigue in Modern People?

In modern society, smartphones and computers have become indispensable, leading many people to overwork their eyes. Whether on a crowded train, at work, or at home, we are constantly facing screens. This digital-heavy lifestyle puts an unnoticed strain on our eyes, which manifests as "eye fatigue."

So, what exactly causes eye fatigue? The three main causes are as follows:

1. Overuse of the Focusing Function
   Staring at a smartphone or PC screen for long periods causes the ciliary muscle, which focuses the eye, to remain tense. The muscle contracts to look at nearby objects and relaxes to look at distant ones. However, constantly looking at screens causes this muscle to stiffen, making it difficult to focus smoothly. This leads to pain deep within the eye and blurry vision.

2. Damage from Blue Light
   "Blue light" emitted from smartphones, computers, and LED lighting is a high-energy light similar to ultraviolet rays. This light is thought to reach the retina at the back of the eye and cause damage. Blue light has been noted to contribute not only to eye fatigue but also to shoulder stiffness and poor sleep quality.

These causes are intricately intertwined, and our eyes accumulate fatigue on a daily basis. DHC supplements provide support for these types of eye fatigue through different approaches.

DHC Supplements That Address Eye Fatigue

• Main Ingredients: Blueberry (anthocyanin), cassis extract, beta-carotene, lutein, lycopene, B vitamins

• Approach to Eye Fatigue:

  • Anthocyanin: Assists in the re-synthesis of "rhodopsin," a substance necessary for sensing light, and supports the eye's focusing function.
  • Other Ingredients: Beta-carotene and B vitamins provide comprehensive support for eye health.

• Recommended for People Who:

  • Use computers and smartphones for long hours and are concerned about eye fatigue
  • Get blurry vision or eye strain from reading small text or long periods of reading

• Main Ingredients: Blueberry (anthocyanin), crocetin, lutein, astaxanthin, cassis extract, B vitamins
• Approach to Eye Fatigue:
  • Crocetin: Eases the tension in the ciliary muscle, which is involved in eye focusing, providing powerful support for the focusing function.
  • Anthocyanin, Lutein, and Astaxanthin: Provides a multifaceted approach to fundamentally care for eye fatigue, including focusing, blue light protection, and reduced oxidative stress.
• Recommended for People Who:
  • Have chronic and severe eye fatigue concerns
  • Often have difficulty focusing and experience blurry vision
  • Want to simultaneously care for not only eye fatigue but also damage from blue light and aging

• Main Ingredients: Lutein, crocetin
• Approach to Eye Fatigue:
  • Lutein: A pigment found in the macula of the retina that absorbs blue light from computers and smartphones, protecting the eyes from light irritation.
  • Crocetin: Supports the focusing function and reduces eye fatigue.
• Recommended for People Who:
  • Use smartphones and computers all day and are concerned about eye fatigue from blue light
  • Want to protect their eyes from digital devices and preserve future eye health
  • Experience deep-seated eye pain or eye fatigue accompanied by shoulder stiffness

• Main Ingredients: Astaxanthin, Haematococcus algae pigment, vitamin E
• Approach to Eye Fatigue:
  • Astaxanthin: With a powerful antioxidant effect, it helps reduce oxidative stress on the ciliary muscle, which is responsible for focusing, and supports fatigue recovery.
  • Improved Blood Circulation: It is also reported to improve blood flow around the eyes, which can prevent the accumulation of fatigue-causing substances.
• Recommended for People Who:
  • Have difficulty focusing and feel a heavy sensation deep within their eyes
  • Experience shoulder or neck stiffness from eye fatigue
  • Want to fundamentally care for eye fatigue and also address eye aging

Explaining the Differences Between the 3 Ingredients

Blueberry Addresses "Eye Focusing"

Anthocyanin, found abundantly in blueberries, particularly Nordic bilberries, plays a crucial role in focusing the eye. Our eyes contain a substance called "rhodopsin," which senses light and sends visual information to the brain. Staring at a smartphone or PC screen for extended periods can cause the re-synthesis of rhodopsin to fall behind, making it difficult to focus. Anthocyanin helps with the re-synthesis of rhodopsin, smoothing out the eye's focusing function and alleviating eye strain and blurriness.

Lutein Protects Eyes from "Blue Light Irritation"

Lutein is a pigment found in high concentrations in the "macula," a part of our eye's retina. The macula is the most important part for vision and directly receives light irritation, especially from blue light emitted by PCs and smartphones. Lutein acts like a filter, absorbing this blue light and protecting the eyes. This can reduce deep-seated eye pain and fatigue caused by blue light and help prevent eye damage.

Astaxanthin Supports "Eye Fatigue Recovery" and "Blood Circulation"

Astaxanthin is a red pigment found in ingredients like shrimp, crabs, and salmon, known for its powerful antioxidant effects. The ciliary muscle, which is responsible for focusing, is prone to oxidative stress from free radicals due to long hours of tension and overuse. Astaxanthin helps the ciliary muscle recover from fatigue by reducing this oxidative stress. It is also reported to improve blood circulation around the eyes, which can help alleviate symptoms like deep-seated eye pain and shoulder/neck stiffness caused by eye fatigue.

Precautions and Recommended Usage

• Supplements are food products, not medications, so it is important to take them consistently every day.

• Follow the recommended dosage: Always adhere to the daily dosage indicated on the package.

• Take with meals: Many ingredients are fat-soluble, so taking them during or after a meal with some oil content can increase absorption.

• Be cautious when combining multiple supplements: You might end up taking an excessive amount of the same ingredient. When combining supplements, check the ingredients carefully to avoid duplication.

• Stop use if you feel any change: If you feel any physical discomfort or a negative reaction, stop use immediately and consult a doctor or pharmacist if necessary.

Frequently Asked Questions

Q1: When is the most effective time to take supplements?

A1: There are no specific rules for the time of day, but since many ingredients are fat-soluble, taking them during or after a meal with some oil content is said to enhance absorption. To avoid forgetting, it's a good idea to set a consistent time each day that fits your lifestyle.

Q2: Is it okay to take multiple supplements at once?

A2: Generally, there is no problem, but you may risk taking an excessive amount of the same ingredient. For example, "Speedy Blueberry V-MAX" contains both lutein and astaxanthin. If you are combining multiple products, please check the ingredients carefully to avoid duplication.

Q3: How long does it take to feel the effects?

A3: Supplements are not medications, so immediate effects should not be expected. The way effects are felt varies from person to person, but they work by gradually improving your body's nutritional state. It is recommended to take them consistently for at least 1 to 3 months to see results.

Q4: Are there any side effects?

A4: As supplements are food products, the risk of side effects is generally low. However, in rare cases, some people may feel they do not agree with their body, depending on their constitution or physical condition. If you feel any physical discomfort, stop using the product immediately and consult a doctor or pharmacist if necessary.

Q5: I am taking medication. Can I still take supplements?

A5: If you are taking any regular medication, the ingredients in the supplement may affect the medication's efficacy. Please consult your family doctor or pharmacist before starting to take any supplements.
