Spending long hours staring at a computer or smartphone screen can cause eye strain and fatigue. This often leads to discomfort, including dizziness, headaches, and blurred vision. To alleviate these symptoms, performing simple eye exercises can be an effective way to reduce eye strain.

Benefits of Eye Exercises to Improve Vision

Our daily routines often make it difficult to take regular breaks from screens. Extended screen time can lead to dry eyes, blurred vision, and headaches due to eye strain. Eye exercises are believed to help alleviate the discomfort caused by this strain.

While the effectiveness of eye exercises in improving vision has not been fully supported by extensive scientific research, there are studies that suggest certain exercises may provide benefits. For example, one study showed that eye exercises could help with convergence issues, where the eyes struggle to focus on nearby objects. Other research indicates that eye exercises might boost cognitive function, particularly in tasks involving attention and memory.

However, it's important to note that while eye exercises can be helpful for certain conditions, they have not been proven to be a cure for other visual or cognitive issues.

Nonetheless, your healthcare provider may recommend eye exercises if you're experiencing symptoms such as:

• Difficulty in focusing when reading
• One eye shifting inward or outward (a condition known as convergence insufficiency)
• Post-surgery recovery to improve muscle control
• Crossed eyes (strabismus)
• Lazy eye (amblyopia)
• Double vision
• Difficulty with depth perception
• Blurred vision
• Eye strain
• Increased sensitivity to light

That said, eye exercises will not resolve problems related to the following conditions:

• Frequent blinking
• Eye spasms
• Paralysis of the eye muscles

Types of Eye Exercises to Improve Vision

1. The 20-20-20 Rule

The 20-20-20 rule is a simple yet effective exercise to relieve eye strain caused by prolonged screen time. Every 20 minutes, take a 20-second break to look at something 20 feet (about 6 meters) away. 

2. Focus Shift

In addition to the 20-20-20 rule, you can incorporate a focus shift exercise into your routine. This exercise is easy and can be done anywhere:

• Sit comfortably and hold one finger about 10 cm (4 inches) from one eye.
• Focus your gaze on your finger.
• Slowly move your finger away from your face while continuing to focus on it.
• Shift your focus to a distant object, then return to your finger.
• Repeat this sequence three times.

3. Basic Eye Movements

This simple eye exercise can be done by both children and adults. Here’s how:

• Close your eyes
• Move them slowly upward, then downward, repeating this motion three times.
• Next, move your eyes slowly to the left and then to the right, also repeating three times.

4. Tracing the Number 8

A fun and easy way to relieve eye strain is by tracing an imaginary number 8. Follow these steps:

• Sit comfortably and focus on a spot on the floor about 3 meters (10 feet) ahead of you.
• Using your eyes, trace an imaginary number 8 on its side (the infinity symbol).
• Continue tracing for 30 seconds, then change direction.

Tips for Maintaining Eye Health

Maintaining eye health is crucial for preventing infections and other visual disorders. Along with regular eye exercises, here are some lifestyle habits that can help keep your eyes healthy:

• Incorporate green leafy vegetables, eggs, nuts, beans, and fatty fish into your diet.
• Quit smoking.
• Protect your eyes from harmful UV rays by wearing UV-blocking sunglasses.
• When engaging in activities such as sports or any tasks that pose a risk to your eyes, wear protective glasses.
• Avoid staring at screens for long periods. 
• Perform tasks in well-lit environments.
• Get regular eye check-ups.

Eye exercises can be a helpful way to relieve the discomfort associated with eye strain. However, they are not a solution for more serious vision problems. If you have any concerns about your eye health or experience persistent symptoms, it’s a good idea to consult an eye specialist. You can also take advantage of the health consultation feature on the Ai Care app, available for download from the App Store or Play Store.
