Why does eye strain sometimes persist after breaks?

Prof. William Dalton, Ph.D.If eye strain persists following breaks, there are underlying issues that have not been dealt with. Temporary relief is often provided, but it is usually overlooked that the actual problems are not being addressed. I frequently encounter these cases in my practice every week. Uncorrected vision is a common cause in these conditions, and very commonly, poor ergonomics is also a contributing factor. In this case, dry eye syndrome is also found frequently at work.
Vision Correction Issues
- Outdated prescriptions create constant focusing strain
- Undiagnosed astigmatism causes distorted vision
- Improper reading glasses magnification for screen work
Ergonomic Failures
- Incorrect screen angles forcing neck contortion
- Improper viewing distances requiring squinting
- Glare sources causing pupil fluctuation fatigue
Ocular Surface Problems
- Advanced dry eye damaging corneal surface
- Blepharitis inflammation disrupting tear film
- Allergic conjunctivitis creating chronic irritation
Insufficient blinking can commonly occur without notice. Taking breaks doesn't alleviate chronic incomplete blinking. I have a technique for measuring blink quality while unique cameras are recording you. Some patients blink only partially during work and then fail to blink at all between tasks. This prevents the tear film from renewing.
Consult medical evaluation when symptoms continue. Optometrists can conduct dry eye assessments and refraction assessments. I recommend testing after 2 weeks if your strain is not relieved. Advanced instruments detect minor corneal injury. Getting checked early on can alleviate chronic effects.
Address factors at the same time. Update medications while fixing ergonomics. Use blink training combined with artificial tears. For stubborn cases, I create personalized plans. Comprehensive strategies are more effective for long-term solutions than monotherapy.
