Dry eye management, particularly in the context of Computer Vision Syndrome (CVS), involves addressing symptoms and underlying causes of dry eye exacerbated by prolonged computer use and other digital screen activities.
Dry Eye Syndrome is a condition where the eyes do not produce enough tears or the tears evaporate too quickly, leading to discomfort and vision problems. Symptoms include dryness, irritation, redness, and a gritty sensation.
Computer Vision Syndrome (CVS) refers to a range of eye and vision-related problems that arise from prolonged computer use, including digital screens.

Management Strategies for Dry Eye and CVS
- Environmental Adjustments:
- Lighting: Reduce glare from screens by using proper lighting and positioning screens away from direct light sources.
- Humidity: Use a humidifier to add moisture to the air, especially in dry environments.
- Screen Use Habits:
- 20-20-20 Rule: Every 20 minutes, take a 20-second break and look at something 20 feet away to reduce eye strain.
- Screen Position: Position your screen at eye level and about an arm’s length away to minimise strain.
- Blinking and Eye Exercises:
- Frequent Blinking: Remind yourself to blink more often to keep the eyes moist.
- Eye Exercises: Perform exercises to reduce eye strain, such as rolling your eyes or focusing on different objects.
- Artificial Tears and Lubricants:
- Over-the-Counter Drops: Use preservative-free artificial tears to help keep the eyes moist.
- Ointments and Gels: For longer-lasting relief, consider using lubricating ointments or gels, especially before bed.
- Proper Eyewear:
- Anti-Reflective Lenses: Glasses with anti-reflective coatings can reduce glare and improve visual comfort.
- Computer Glasses: Specialised glasses for computer use can help reduce eye strain.
- Regular Eye Exams:
- Routine Check-ups: Regular visits to an eye care professional help monitor eye health and adjust treatment plans as needed.
- Personalised Recommendations: Your eye care provider can offer tailored advice and treatments based on your specific needs.
- Addressing Underlying Conditions:
- Medical Treatment: For more severe cases, your eye doctor may recommend prescription medications or procedures to address underlying causes of dry eye.
- Lifestyle Modifications: Managing conditions such as allergies or hormonal changes can also help alleviate dry
