There are many different potential causes of red eyes at the end of the day. An in person eye health exam with an eye doctor is the best for evaluating your cornea, eyelids, conjunctiva and measuring intra ocular pressure. With computer use increasing, another cause of redness could be that you need an updated glasses prescription or healthier types of the newest UV protection contact lenses. An Optometrist like myself would be happy to do a thorough eye exam to determine the cause and then recommend the best treatment for your eyes. 
One of the most common reasons for having red and tired eyes at the end of the day is Dry Eye Syndrome. This affects millions of people and is a lack of one or both glands that produce tears. When you blink every 25 seconds , the two types of tears should come out and protect your eyes from the wind or exposure to light. If the glands that produces oil are not working well the other tear that is liquid will quickly evaporate. Water and oil do not mix, there fire the oily layer is there to be on top of the watery to hold moisture until you blink again. If not there , the basic watery tear will evaporate as soon as you open your eyes in between blinks.
Exposure to computer , tv and driving will make these symptoms worse because you are staring and blinking less. Contact your optometrist to know exactly what type of dry eyes you may have or if it is a different condition that is affecting your eyes.
They are dry and tired. Use tear drops throughout the day like Systane complete 1 drop 3x a day.
You should get your eyes evaluated to see the true cause of your red tired eyes. Redness can be caused by bacteria, viruses, dryness, and allergies even if your eyes do not feel itchy and irritated. Tired eyes may be a sign that the eyes are straining or dry. Also if you use redness drops, then that can cause the redness to come back worse (rebound effect).
If you’re like me and many others these days the extended computer use can wreak havoc. Most likely it’s dry eyes ... Get some rest and blue light protection

Normally, that is a form of evaporative dry eye. It usually is brought on by intensive work (computer, driving, etc.). See your doctor for remedies best suited for you and your situation.
Sometimes it is moist heat therapy, sometimes occupational glasses, sometimes drops, or all of the above.
This is likely due to dryness and/or eyestrain, especially if you spend a lot of time on the computer. When you work on a computer, your eyes don't blink as often as they would typically, therefore your eyes are not being refreshed with a constant cover of tears. This can lead to evaporation and inflammation on the surface of your eye. Subsequently, it will turn red. This can often be improved simply by using lubricating drops (NOT redness-relieving drops) throughout the day and taking visual breaks from the computer. There is a good mnemonic called the "20/20 Rule": every 20 minutes, take a 20 second break and look 20 feet away.

If the redness persists, make sure to follow up with your eye care professional.

Allergy, foreign body, dust in the air, eyestrain viewing a computer, incomplete or infrequent blinking and possibly a dry eye cause by an imbalance of the tear components of water, oil and mucous. DO NOT REACH FOR A RED OUT DROP. These can affect your blood pressure and create a dependence that requires you use the drops continually. Find the cause of your red eye with a visit to an eye care specialist, such as an Optometric Physician, or Optometrist, and follow their directions so you are solving the problem and not just hiding it with red out drops.
Fatigue and tiredness can cause this . Also constantly rubbing the eyes . Take frequent breaks from the computer screen at work
Most likely answer is dry eye syndrome.
