Here are some useful tips to sooth your tired eyes:
Drink plenty of water, at least 10-12 glasses in a day.
Take proper sleep time.
Give some rest to your eyes after one hour for 5-10 minutes and then start working again.
Have a short walk outside to refresh your mind and eyes. Use to sit 30 inches away from your computer and use LCD monitor.

Take two slices of cold cucumber and place these slices on your eyes to refresh your eyes.
Sometimes your eyes become swollen due to even workload. Place used teabags soaked in cold water on your eyes for half an hour.
Pour 5 drops of rose water in your eyes on daily basis. It will irritate your eyes in the beginning use of it but later on it will clean your eyes with no irritation. People with easy work routines should also make it their routine to put rose water in their eyes.
