In this blog we are going to talk about the harmful effects of working long hours on screen and how it leads to the development of dry eye
Long hours of working on the screen severely impact our natural pattern of blinking. Most people when using a computer or similar device do not blink as often as they should, there can be up to 60% less blinking than when not looking at a computer.

Working long hours on bright screen not only reduce the frequency of blinking but it also leads to partial blinks when our eyelids are not touching each other. This severely impact our eyes leading to dry eye.
Blinking has an important role in maintaining a healthy eye, this is because when we blink we stimulate tiny glands which are situated in the eyelids known as Meibomian Glands.
Through complete and frequent healthy blinking, the Meibomian glands are stimulated to release their content on to the eyelid margin to be incorporated and spread into the tear film. These oils protect the tears from evaporating, reducing eye drying, as well as serving an important immune function for the eye. In case of incomplete and infrequent blinking ( which happens when we work long hours on screen), the Meibomian gland function and tear production, spreading and clearance is compromised. This can lead to dry eye
Chronic partial blinking can lead to Meibomian Gland blockage – a condition known as Meibomian Gland dysfunction .
Therefore, it’s important that we pay attention to blinking and there are technology available which can help you in identifying your blinking habits and Meibomian Gland structure.
If you are working long hours on screen and experiencing the symptoms of dry eye, please visit your eye care specialists to assess your blinking health and Meibomian Gland Dysfunction.
