How blinking efficiency affects contact lens wear?

Normal average blinking rate is from 3 blinks/min to 25 blinks/min.  Blinking efficiency normally increase during adaption or discomfort to contact lens wear. It means, during adaption or discomfort, blinking rate is higher than normal.

When contact lens feels comfortable in the eye, blinking rate can be influence by wearer’s personality, mood, fatigue level, visual task, state of alertness and atmosphere condition.

For example, when a contact lens wearer faces the computer for long hours, blinking rate is reduced. Thus, evaporation of the tears from contact lens become higher, especially under air-conditioner condition (environment  is dry). Therefore, contact lens wearer easily complaint of dry eyes.

A complete blink is important as it can helps to position the contact lens properly, promote better tear circulation, eliminate debris under the contact lens and prevent deposits from building up. Incomplete blink or low blinking rate, easily caused contact lens wearers to get dry eyes problems.
