Prof. William Dalton, Ph.D.Proper frequency of lubricating drops will avert chronic ocular dryness while working at a screen. I advise using preservative-free drops exclusively for regular use. Use them 4-6 times per day, preferably before discomfort occurs, to ensure the healthy integrity of the tear film. Air-conditioned offices require even more frequent drug usage.
Frequency Protocol
- Apply 4-6 daily doses during extended screen sessions
- Use preventively before symptoms appear for best results
- Increase to hourly in air-conditioned or heated environments
Formulation Selection
- Choose preservative-free formulas for frequent application
- Avoid benzalkonium chloride due to tear film disruption
- Select viscosity matching your specific dryness severity
Environmental Adaptation
- Increase frequency during air travel or low humidity
- Store drops at room temperature for comfortable instillation
- Pair with humidifiers in climate-controlled spaces
To benefit most from drops, place them in the eye correctly. Slightly tilt your head back. Pull the lower eyelid down to create a small pouch. Put one drop in ( do not let the drop touch the eye). Gently blink to distribute the drops. I teach this technique to my patients during education sessions. Proper technique will also help to eliminate contamination and loss of medicine.
Use your drops before beginning screen time. Then, use drops after finishing strenuous visual work. I put the drops in during coffee breaks. By administering the drops at the same time every day, your baseline eye moisture is kept stable. Your eyes, therefore, remain comfortable during times when especially intense focus is required.
Avoid common mistakes, including excessive use of preserved drops. Benzalkonium chloride damages the ocular surface after 4 daily uses. Never share dropper bottles. I educate patients about expiration dates. Discard preservative-free vials 12 hours after opening. Proper storage prevents contamination.
