1. Eye Drops
Eye drops are sterile liquid preparations containing one or more medicinal substances, administered into the eyes to treat various eye conditions. Eye drops can be formulated as sterile powders, which are reconstituted with a suitable sterile liquid before use. The solvent for preparing eye drops is usually distilled water, which must be sterile and meet the requirements specified in the pharmacopoeia. Vegetable oil can also be used as a solvent for eye drops. Vegetable oil exists in a liquid state at room temperature and does not irritate the eyes. The best oil is castor oil, as it has a soothing effect on the eye mucosa.
Currently, there are many eye care products available on the market. Choose a reputable brand to take care of your eyes. When sitting for an extended period in front of the computer, having a bottle of eye drops is essential for relieving dryness in your eyes. Remember to discard the first drop before applying the medication directly to your eyes, as it helps wash away any dust and bacteria on the bottle's mouth that may have accumulated during the unused period.

2. Blinking and Winking
Blinking is an involuntary movement that usually occurs in both eyes, caused by the contraction of the muscles under the eyelid, the circular muscles in front of the cartilage, and the eyebrow arch muscles. Blinking occurs suddenly in a few seconds and can last for a few minutes. When blinking, the muscles in the facial area may also twitch. We often experience unintentional blinking, and people usually overlook this. However, if blinking occurs continuously in one session and happens regularly... could it be something unhealthy? Normally, we blink 12 times per minute, and each blink lasts for 0.5 seconds.
In fact, blinking is not entirely worrisome. Sometimes blinking also has positive effects. For example: When the eyes have been active for a long time causing fatigue, or there is a sudden impact from the environment on the circular fibers in the eye's eyelid, muscle contraction occurs, leading to blinking. A single blink, even though it occurs very briefly, in 1/10 of a second, has the effect of reducing eye strain, preventing dry eyes, and removing dust particles that may have entered the eyes.

3. Look into the Green
Nature is filled with various colors, each evoking different sensations. Intense colors can make us feel tired when stared at for too long, dull colors can create a burdensome feeling, and red or yellow can induce a dazzling effect. However, green and blue colors provide a refreshing and tranquil sensation. Due to the neutral absorption and reflection of light by blue and green, the human nervous system, brain, and retina can easily adapt. The green color of grass helps reduce the harmful effects of reflected ultraviolet rays on the eyes, minimizing eye stimulation.
Scientists have also proven that among all the colors visible to the human eye, green is the best. This holds true for both green and blue sea colors. That's why, when stressed, people tend to seek the refreshing countryside or the cool beach. The colors in these environments make our nerves feel gentle. From this knowledge, we can deduce that when working excessively and causing eye fatigue, you can shift your gaze to objects with green hues. It helps minimize light stimulation for the eyes, making them feel more comfortable.

4. Write Alphabets with Your Eyes
Writing alphabets with your eyes is an interesting exercise often recommended by international schools. Look straight at the wall or the space in front of you, use your eyes to trace and form alphabets. Keep your head still, gaze at the empty space or wall in front, use your eyes to create letters or shapes like squares, triangles based on your preference. Try to write larger letters for better results. This movement might be challenging initially, but persist as it is a beneficial exercise for your eyes.
Train your eyes to write letters from small to large to enhance flexibility and sharpness. In the beginning, it may seem difficult, but once accustomed, you'll find it truly beneficial for relaxing your eyes after hours of intense work.

5. Read Books
Everyone knows that books contain a wealth of knowledge for life. They help us think, perceive deeply, grow, and accumulate a rich vocabulary. So why not maintain a habit of reading books daily or whenever possible, as an appreciation of life, akin to a rich experience across each page of a book.
However, in modern society, many people tend to read information on electronic devices instead of traditional books. While this may save you time and money, it is extremely harmful to the eyes and brain due to the harmful electromagnetic waves emitted by these devices. Combine the moderate use of electronic devices with reading books to help protect and care for your eyes better. Additionally, reading physical books directly will also help prevent eye diseases such as myopia and astigmatism.

6. Eye Massage
Extended work hours and excessive use of technology can make you feel tired, especially your eyes. When your eyes are overworked, your vision will deteriorate quickly, and the skin around your eyes will develop dark circles and puffiness. Remember the rule of working for 30 minutes and taking a 5-minute break. During breaks, besides walking around and stretching your arms, perform some eye massage exercises. Don't wait until wrinkles and dark circles appear to start taking care of your eyes.
For women, keeping the eyes free from dark circles, the skin around the eyes will be smooth, slowing down the aging process, and maintaining youthful freshness for a longer time. Eye bags and ugly dark circles will no longer be a concern. Sophisticated computers make your eyes work excessively for 16 hours every day, and over time, this can lead to various problems such as dizziness, visual disturbances, headaches, eye fatigue, and reduced vision. Regular eye massage helps slow down the progression of eye conditions such as myopia, hyperopia, and astigmatism. It prevents or reduces the risk of worsening myopia if you consistently massage your eyes every day. This helps relieve pressure on the eyes, regulates blood vessels on the face, provides a comfortable feeling, and dispels fatigue.

7. Apply Eye Masks
Recognize the importance of your eyes, equal to or more than your skin. Because the costs of treating eye conditions are always high. If you usually reserve your weekend evenings for applying face masks, don't forget your eyes. When applying the mask, make sure to clean and dry your face before applying. Avoid applying the mask to the eye area when there is still makeup residue. Gently press some points around the eyes before applying the mask. After pressing, apply a balanced essence or lotion around the eyes to allow the mask material to be more effective.
Follow the recommended time for the mask, there is no need to leave it on the eyes for too long with the thought 'the longer, the better.' It's best to apply an eye mask in the evening, once a week. If you work extensively on a computer or engage in activities that require eye adjustment for extended hours, such as sewing, drawing, or photography, consider applying the eye mask more frequently, from 2 to 4 times a week. When applying, relax with gentle music.

8. Apply Chilled Spoons on Eyes
One of the simplest remedies for relieving tired eyes is placing two spoons in the refrigerator. Leave the spoons in the fridge for a while, take them out after 5 minutes, and gently apply them to your eyes for an incredibly refreshing sensation. This is considered one of the simplest stress-relieving therapies for the eyes.
Remember that if you accidentally leave the spoons in the fridge for too long, you should never apply them to your eyes immediately after taking them out. Allow the spoons to return to normal temperature to avoid harming the delicate skin around the eyes.

9. Nutritional Diet
In addition to exercise, a nutritional diet also needs attention if you want to have healthy eyes. When experiencing eye strain, consume plenty of tomatoes, bananas, and carrots. These fruits are rich in vitamin A, which is beneficial for the eyes. Alternatively, if you want to follow the green rule, enjoy beverages made from green tea. It not only cools the eyes when consumed but also provides nutrients to relax the nervous system, reducing stress and pressure on the eyes.
To cultivate healthy eyes, supplement foods that enhance blood circulation. Include foods such as: tropical fruits, whole grains, and dark green vegetables. Add zinc-rich foods like pumpkin seeds, red meat, oysters, and poultry. Other nutrients that promote eye health include beta-carotene (found in yellow and orange fruits), lutein, and zeaxanthin.

10. Regular Eye Check-ups
One of the most effective ways to care for your eyes is to regularly go for eye check-ups. Everyone, including children, should have regular eye examinations to safeguard their vision. Eye exams help detect eye conditions such as increased intraocular pressure, refractive errors, and more. Early detection makes treatment easier and more convenient.
Therefore, it's essential to schedule regular eye check-ups, at least once a year, to quickly identify and treat any emerging eye issues.

11. Blinking Exercise
Similar to any other part of the body, your eyes need rest to restore their capabilities. Blink your eyes tightly for 3 to 5 minutes and maintain a relaxed body posture to help your eyes regain balance. You can combine this with listening to music or use a cloth to cover your eyes to minimize light exposure.
Additionally, you can warm your eyes with your hands by closing your eyes and placing your hands over them. Then, look straight into darkness and maintain this position for about 10 minutes. Allowing your eyes to rest is a measure to care for your eyes and keep them healthier.

12. Wear Sunglasses When Going Out
Sunglasses not only have a fashionable aspect but also play a significant role in protecting your eyes, keeping them bright and healthy. Direct exposure of your eyes to ultraviolet (UV) rays from sunlight can lead to the risk of cataracts and macular degeneration.
In reality, when you are in the sun without eye protection, you may not feel any immediate difference. However, after a short period, your eyes might experience a condition called photokeratitis due to brief exposure to ultraviolet radiation. Therefore, choose the right sunglasses that block 99-100% of both UVA and UVB rays. Additionally, sunglasses reduce glare when driving, preventing you from squinting and thereby minimizing the early appearance of crow's feet around the eyes.
