Tips for reducing digital eye strain
Here are some simple tips to protect your eyes from eye strain:
Adjust your computer screen: Position your computer screen 20 to 28 inches from your eyes, place the screen slightly below eye level, and adjust the contrast, brightness, and font size on your device.
Blink frequently: Blinking helps prevent your eyes from drying out, and looking at a computer or digital screen may cause you to blink less often than you should. Try taking regular breaks from your screen to give your eyes a rest.
Reduce screen glare or bright light: Try to reduce or eliminate glare by:
shades, or curtains on windows,
using lower wattage light bulbs,
dimming overhead lights, or
adding a screen glare filter to your computer.
Use the right eyeglasses: Blue light filtering glasses or blue light filtering lenses are designed to reduce the amount of blue light that reaches the eyes when using digital devices such as computer screens causing digital eye strain and fatigue, making it difficult for the eyes to focus for long periods of prolonged computer use.
Take regular breaks and eye exercises: Regular breaks and eye exercises can help reduce eye strain and give your eyes a rest.
Proper lighting and monitor positioning: Proper lighting and monitor positioning can help reduce glare and make it easier for your eyes to focus.
Regular eye exams: Regular eye exams can help detect CVS early on and prevent serious eye-related problems in the future.
Eye strain and the 20-20-20 rule
The 20-20-20 rule is a simple technique to minimize the risk of developing computer vision syndrome (CVS) or digital eye strain.
The rule states that every 20 minutes, you should take a 20-second break and look at something that is at least 20 feet away.
This can help reduce eye strain caused by prolonged use of a digital device and giving your eyes a chance to relax, refocus and reduce the strain caused by staring a screen for a long time.
This can be especially helpful for people who spend hours in front of a computer or other digital devices.
To use the 20-20-20 rule, you can set a timer to remind you to take a break every 20 minutes and look at an object 20 feet away or farther for 20 seconds.
This simple technique can help you reduce the risk of Computer Vision Syndrome, headaches, and eye fatigue.
Where did the 20 seconds in the 20-20-20 rule come from?
The reason for the 20 seconds break is that this is the approximate time it takes for the eyes to relax and refocus.
Prolonged use of digital screens can cause the eyes to become fatigued and overworked, and the 20-second break allows the eyes to rest and recover.
By looking at something that is at least 20 feet away, you are also engaging the eyes in a different distance focus and reducing the strain caused by staring at a digital screen for a long time.
This short break can also be beneficial for people who spend hours in front of a computer or other digital devices.
The 20-20-20 rule is a simple and effective way to reduce the risk of Computer Vision Syndrome, headaches, and eye fatigue.
How to remind yourself to take a break?
Sticking to the 20-20-20 rule can be difficult when you're deeply engrossed in reading or work on a digital screen.
Setting a reminder every 20 minutes can help you to take a break and follow the rule.
There are also apps like Eye Care 20 20 20 that can help you to stay on track.
Simply start the app when you begin your screen time, and it will remind you to take a break and look at something 20 feet away for 20 seconds every 20 minutes.
Do eye drops help alleviate eye symptoms?
If you are experiencing dry eye symptoms, using lubricating eye drops can help to keep your eyes moisturized and reduce discomfort. These drops can be found over-the-counter (OTC) and come in various forms.
In some cases, reducing digital screen time can help alleviate Computer Vision Syndrome. Implementing the lifestyle changes mentioned above can also prevent or ease symptoms.
However, if symptoms persist or worsen, it's important to consult an eye doctor. This is especially important if you experience sudden vision changes, eye flashes, unexplained eye pain or redness that doesn't go away, or dry eyes that don't improve with eye drops.
These symptoms may indicate an underlying vision issue or health condition. Your eye doctor may prescribe computer glasses or suggest visual therapy or specific eye drops for Computer Vision Syndrome.
Does drinking green tea help with eye strain?
There is some evidence to suggest that drinking green tea may help with reducing eye strain. Green tea contains antioxidants, specifically catechins, which have been shown to have anti-inflammatory properties.
Inflammation in the eyes is one of the factors that can contribute to eye strain. By consuming green tea, you may be able to reduce the inflammation in the eyes and alleviate some of the symptoms of eye strain.
Additionally, green tea also contains caffeine, which can help to improve blood flow to the eyes, which can help to improve vision and reduce eye strain.
It's worth noting that while drinking green tea may be beneficial, it's not a substitute for other techniques to reduce eye strain such as the 20-20-20 rule or taking breaks regularly. It's also important to consume green tea in moderation as excessive caffeine intake can have negative effects on the body.
Therefore, drinking green tea in moderation in combination with other techniques to reduce eye strain may be helpful in reducing eye strain symptoms.
The science and research says:
The American Academy of Ophthalmology (AAO) has conducted research on the effects of prolonged screen time on the eyes. According to the AAO, when using digital screens, the average person blinks 66% less than when not using screens. This reduction in blinking can lead to dry eyes, irritation, and eye strain.
The AAO also reports that prolonged screen use can cause a number of symptoms such as eye fatigue, headaches, and blurred vision, collectively known as Computer Vision Syndrome (CVS).
Other studies have also found a link between prolonged computer use and eye strain. A study published in the journal Ophthalmology found that prolonged computer use is associated with symptoms of dry eyes, visual fatigue, and ocular discomfort.
Another study published in the journal Optometry and Vision Science found that prolonged computer use is associated with symptoms of eye strain and dry eyes.
The AAO and other organizations recommend taking breaks, adjusting your screen settings and positioning, and using eye drops, blue light filters and the 20-20-20 rule to reduce the risk of digital eye strain.
Regular eye exams and consulting with an eye doctor can also help to detect and prevent any underlying vision issues.
