Screen Time & Posture Risk Estimator

Spending long periods of time looking at screens can contribute to eye strain and body discomfort. When you focus on a screen for extended periods, your eyes work harder, and your body may stay in the same position for too long.

Common issues that can arise from long screen sessions include:

• Eye strain: Dry eyes, tired eyes, blurred vision, or needing to squint can occur when focusing on screens for long periods without breaks.
• Neck and shoulder tension: Holding your head and neck in the same position for extended periods can lead to muscle tension and discomfort.
• Back discomfort: Sitting in the same position for long periods, especially with poor posture, can contribute to back pain.
• Wrist and hand issues: Repetitive typing or mouse use without breaks can contribute to wrist and hand discomfort.

Taking regular breaks, adjusting your setup, and varying your position can help reduce these issues. However, this tool provides general educational information only and cannot diagnose or treat any specific condition.

Basic posture concepts can help reduce strain when working with screens. These are general guidelines, not medical advice:

Neutral Spine

A neutral spine position generally means keeping your back relatively straight, with your ears roughly aligned over your shoulders and your shoulders over your hips. This helps distribute weight evenly and reduces strain on your back and neck.

Screen at Roughly Eye Height

Positioning your screen so the top is roughly at eye level when you're sitting upright can help reduce neck strain. If your screen is too low, you may crane your neck downward. If it's too high, you may tilt your head back.

Reasonable Distance

Keeping your screen at a comfortable distance (often around arm's length) can help reduce eye strain. If you're very close to the screen, your eyes work harder to focus, which can contribute to eye strain.

Taking regular breaks and incorporating movement into your day can help reduce strain from screen time and prolonged sitting.

Eye Breaks

Looking away from your screen periodically gives your eyes a chance to rest and refocus. The "20-20-20" rule is a simple guideline: every 20 minutes, look at something about 20 feet away for about 20 seconds. This is a general suggestion, not a medical prescription.

Movement Breaks

Standing up, walking around, or doing light stretches can help reduce muscle tension and improve circulation. Even short breaks of a minute or two can make a difference.

Posture Variation

Changing your position throughout the day can help prevent prolonged strain in one area. If possible, mix sitting and standing, or adjust your chair and screen position periodically.

While general ergonomic adjustments and breaks can help reduce strain, persistent or severe pain, numbness, weakness, vision changes, or headaches should be evaluated by a healthcare professional.

Professional evaluation is important because:

• Accurate diagnosis: A healthcare professional can help determine the underlying cause of your symptoms, which may or may not be related to screen time or posture.
• Personalized treatment: Treatment plans should be tailored to your specific condition, medical history, and individual needs.
• Preventing complications: Some conditions can worsen if not properly addressed, so early evaluation and treatment can be important.
• Ruling out serious conditions: Some symptoms can indicate more serious underlying conditions that require medical attention.

This tool cannot diagnose or treat any condition. It provides general educational information only. If you have persistent or severe symptoms, consult with a healthcare professional such as a doctor, physical therapist, optometrist, or ergonomics specialist.
