Introduction
In the era of digital devices, eye strain and computer vision syndrome have become daily complaints. As an optician, you have an excellent opportunity to educate your clients on simple ways to protect their eyesight.
1. Computer Vision Syndrome (CVS)
Common symptoms include eye fatigue, headaches, double vision, and dry eyes. These can be greatly reduced with proper measures.
2. The 20‑20‑20 Rule
Every 20 minutes, take a 20‑second break and focus on an object at least 20 feet (about 6 meters) away. This rule helps relax the eye muscles and prevent strain and dryness.
3. Blue‑Light Filtering Lenses
Anti‑reflective lenses with a blue‑light filter reduce exposure to screen light wavelengths, easing discomfort and protecting the retina over time.
4. Ergonomics and Setup
– Position screens 50–70 cm from the eyes, slightly below eye level.
– Use soft ambient lighting to avoid harsh contrasts.
5. Regular Eye Exams
Recommend an eye exam every 12 months—or more frequently for those who spend long hours at a screen.
Conclusion
By adopting these practices and using appropriate products (anti‑reflective coatings, blue‑light lenses), your clients can enjoy long hours of work without ocular discomfort.
