in such a kind of condition？There is no need to worry about it because it is so common nowadays. On the contrary, you should find the factors and then seek some appropriate treatments for them.

　　Some folks don't wish to waste even a second at work, even to blink (眨眼) for a fraction of a second. Staring constantly at the screen can cause stress to one's eyes. Sitting and staring at the television screen for hours can also make the eyes tired.

　　Bookworms love reading and they will make sure they read much more than their bodies can deal with. The desire to finish a book may result in fast reading, without taking breaks, which can lead to tired eyes. Continuous reading in dim light can also cause pressure to the eyes.

　　Decreased water intake and overindulgence (过度放纵) in salt­based junk food items like burgers, pizzas, etc. also play a role in causing tired eyes. These junk food items do not furnish the body with the required essential nutrients, thus causing a lack ot vitamins, which also has an effect on tired eyes.

　　Stress at the workplace or at home and a noisy sleeping environment cannot bring enough sleep at night. Lack of sleep causes the eyes to become heavy. Dark circles are also seen to develop if one doesn't get sufficient sleep over a period of time.

　　Even though this condition is not fatal, it is stressful for the health of the body, and must be treated. If not treated on time, the condition can become worse and result in double or blurred vision. Here are some ways to treat the tired eye condition.

　　Every hour during your day at work, spend a minute relaxing your eyes. Look away from your computer screen and roll your eyes in both directions. Try and blink more often. Look around the room or close your eyes for a minute if you want and then work again. Following this every hour will help reduce overall stress on your eyes, and you won't feel so tired after work.

　　Caffeine present in the tea helps relieve tired eyes. Make a cup of hot black tea and pour it into a glass. Hold the glass close to your eyes, so that the vapors from the tea reach your eyes. This may be troublesome, so instead you can also use tea bags to relieve your eyes. Dip two black tea bags in a cup of hot water and once the warmth is bearable place the warm tea bags onto your eyes. This will also make you feel flesh.

　　If your eyes feel extremely tired at work, go to the washroom and wash your face with cool tap water. The cold water will help relieve the tired feeling. Do this every hour during work and you will find relief.
