Computer Vision Syndrome
A group of eye and vision-related problems caused by extended screen use -- common, manageable, and often improved significantly with the right adjustments.

Even without obvious symptoms yet, regular screen use is worth flagging during a comprehensive checkup, since early changes in focusing comfort are easier to address before they become a daily complaint.
Dealing with eye strain, headaches, or blurry vision by evening?
Eye fatigue, headaches, and temporary blurred vision that build up over the course of a screen-heavy day are the classic pattern of computer vision syndrome, and they're very treatable once identified.
What Is It?
Computer vision syndrome, also called digital eye strain, refers to a cluster of symptoms — eye strain, headaches, blurred vision, and dry eyes — that develop from extended screen use. It’s not a single underlying disease but rather a predictable consequence of how the eyes are used during prolonged near-focused, screen-based work.
The good news is that computer vision syndrome responds well to relatively simple interventions: correcting any underlying refractive error, adjusting screen setup and lighting, building in regular visual breaks, and managing the dryness that often accompanies reduced blinking during screen use. A comprehensive eye checkup can identify which of these factors is contributing most in your specific case.
Risk Factors
- Extended daily screen use (computers, phones, tablets)
- Uncorrected or under-corrected refractive error
- Poor lighting or screen glare
- Incorrect viewing distance or screen position
- Reduced blink rate during screen use
Symptoms
- Eye strain or fatigue
- Headaches, often by mid-afternoon or evening
- Blurred vision, especially after extended screen sessions
- Dry or irritated eyes
- Neck and shoulder discomfort related to screen posture
Treatment
- Updated Glasses Prescription: Correcting even mild, previously unnoticed refractive error often meaningfully reduces strain.
- The 20-20-20 Rule: Looking at something 20 feet away for 20 seconds every 20 minutes, to give focusing muscles regular breaks.
- Screen Setup Adjustments: Optimizing screen distance, height, and lighting to reduce glare and unnecessary strain.
- Lubricating Drops: Addressing the dryness that often accompanies reduced blink rate during screen use.
