Why Your Eyes Feel Tired All the Time - and How to Get Relief

Do your eyes feel heavy, sore, or strained by the end of the day? Eye fatigue is one of the most common complaints eye doctors hear - and while it’s often dismissed as “normal,” persistent tired eyes are usually a sign that something needs attention. The good news is that most causes of eye fatigue are treatable once you understand what’s behind them.

An Outdated or Incorrect Prescription

If your glasses or contact lens prescription is no longer accurate, your eyes are forced to work harder to focus. Even small prescription changes can lead to eye strain, headaches, blurred vision, and a constant feeling of tired eyes - especially after reading or screen use. Many people don’t realize their prescription has changed until discomfort becomes noticeable.

Computer Vision Syndrome

Spending long hours on digital devices can take a serious toll on your eyes. Computer Vision Syndrome occurs when prolonged screen use causes symptoms such as eye strain, dryness, headaches, and difficulty focusing. Staring at screens reduces how often you blink and forces your eyes to maintain a constant near focus, leading to muscle fatigue over time.

Dry Eye Disease

Dry eyes are another major contributor to eye fatigue. When your eyes don’t produce enough quality tears or tears evaporate too quickly, the surface of the eye becomes irritated and inflamed. This can cause burning, redness, blurred vision, and a heavy, tired sensation that worsens throughout the day, especially with screen use or in dry environments.

The Importance of Annual Comprehensive Eye Exams

Regular comprehensive eye exams are essential for maintaining comfortable, healthy vision. Even if you think your vision hasn’t changed, annual exams allow your eye doctor to:

• Detect prescription changes before symptoms worsen

• Identify dry eye disease or other underlying conditions

• Recommend lenses or treatments tailored to your lifestyle

• Catch early signs of eye health issues that may not yet cause symptoms

Skipping eye exams often means struggling with unnecessary eye fatigue that could be easily relieved.

Healthy Screen Time Habits for Happier Eyes

Simple daily habits can make a big difference in reducing eye strain:

• Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds

• Blink more often, especially during screen use

• Position screens slightly below eye level and at arm’s length

• Use proper lighting to reduce glare

• Take regular breaks from digital devices whenever possible

These small adjustments help reduce eye muscle strain and support better tear stability.

When to See Your Eye Doctor

Occasional eye tiredness happens, but persistent or worsening symptoms are not something you should ignore. Schedule an eye exam if you experience:

• Frequent eye strain or headaches

• Blurred or fluctuating vision

• Burning, dryness, or redness

• Difficulty focusing after screen use

• Eye fatigue that interferes with daily activities

Our eye doctor can pinpoint the cause and recommend personalized solutions - whether that’s an updated prescription, specialty lenses, or dry eye treatment.
