My eyes become blurry after looking at things for a long time

Blurred vision after looking at things for a long time is usually caused by eye fatigue. To alleviate this symptom, you must pay more attention to rest, try not to look at things close for a long time, and pay more attention to looking into the distance. This can alleviate the phenomenon of blurred vision. You also need to pay attention to rest, develop good living habits, and try to eat more foods that are good for the eyes. These are very good auxiliary effects in relieving eye fatigue.

What to eat is good for your eyes

Foods containing vitamin C are also good for the eyes. Vitamin C is one of the components of the lens of the eye. If you lack vitamin C, you are prone to cataracts, which is a cloudy lens. Therefore, you should pay attention to taking foods rich in vitamin C in your daily diet, such as various fresh vegetables and fruits, especially green peppers, cucumbers, cauliflower, Chinese cabbage, fresh dates, raw pears and oranges.

Vitamin A can also prevent and treat dry eyes. Long-term vitamin A deficiency can eliminate eye fatigue. You should take enough vitamin A every day. The best sources of vitamin A are livers of various animals, cod liver oil, milk and eggs, plant foods such as carrots, amaranth, spinach, leeks, green peppers, red sweet potatoes, and carotene in fruits such as oranges, apricots, and persimmons.

Rich calcium powder is also good for the eyes, as calcium can eliminate eye strain. Beans, green leafy vegetables, and dried shrimps are all rich in calcium. Cooking methods such as roasted pork ribs soup, sweet and sour pork ribs with cod, etc. can increase the calcium content. I hope young parents will give their children more eye-friendly foods to promote their healthy growth.

Such as lean meat, poultry offal, fish and shrimp, milk, eggs, beans, etc., which are rich in protein, and protein is the main component of cells. The repair and renewal of tissues requires continuous replenishment of protein. Foods containing vitamin A are also good for the eyes. When vitamin A is deficient, the eyes' ability to adapt to dark environments is reduced, and in severe cases, it is easy to suffer from sleepwalking.

Methods for protecting children's eyesight

1. Parents should check their children's vision regularly so as to detect children with poor vision at an early stage, find out the causes, and take appropriate preventive measures. For example, students whose eyesight is declining and whose studies are affected must wear corrective glasses. The formula of the glasses must be determined by a specialized ophthalmologist, and they cannot borrow other people's glasses. People with severe myopia should avoid participating in various intense sports to prevent serious consequences such as retinal detachment.

2. Guide children to develop good eye habits from an early age and pay attention to eye hygiene consciously. The posture should be correct when reading and writing, that is, the head should be straight, not tilted, and the eyes should maintain a certain distance from the desk surface and the book. Generally, the distance should be more than 30 to 35 cm, and not less than 25 cm. When reading, make sure the written page is at right angles to your line of sight so that the strokes of each character extend to the largest angle of view formed by the eyes and the image of the character formed on the retina is clearest. Therefore, it is best to raise the top of the book appropriately or prop it up with your hands so that the book forms a 30° to 40° angle with the table. At this time, as long as you tilt your head slightly forward, the text on the book will appear clearest.

Don't read while walking or riding in a car. Don't tilt your head to write or read while lying down. Because it is not easy to maintain a suitable distance between the eyes and the book, and the distance has to be changed constantly, which makes the eyes easily tired. It is also easy to form strabismus while reading while lying down.

Children should not watch TV for too long and should keep a certain distance. Generally, you should take a 5-10 minute break after watching TV for half an hour. The position of the eyes and the TV screen should be slightly lower than that of children's eyes. The distance should generally be 5 to 7 times the diagonal of the screen. A certain level of illumination must be maintained indoors to avoid glare. After watching TV, you can do some relaxing whole-body activities or eye exercises. At the same time, the time spent watching TV should not be too long.

3. Children’s learning environment must ensure appropriate lighting conditions. Whether at school or at home, you should study in sufficient bright light. Do not read in dim light or moonlight; and certainly do not read at dusk, dawn, or when it is dark.

Reading in direct sunlight or under harsh electric light can produce strong glare, which can hurt your eyes and affect your vision. Reading by candlelight or unshaded kerosene lamps is most harmful to the eyes because their flickering light can cause headaches and dizziness. Therefore, do not read under the above light.

When reading, the light source should come from the upper left to avoid glare and shadows caused by light from other directions that interfere with reading and writing. The position of the light source can be adjusted appropriately according to the brightness, for example, a bulb with a larger wattage can be placed higher, a bulb with a smaller wattage can be placed lower, and so on.
