What are the Causes of Dry Eyes
The normal blinking rate of your eye is reduced during extensive concentration or
constantly staring at the screen. The contact between the eye surface and the air is also
increased. This causes disruption in the normal tear production and its stay in the eye.
The meibomian glands in the eyelids produce mucin, a part of the tear film, due to
infrequent blinking the squeezing time is reduced and can lead to tear film disruption.
This implies that the normal blink rate should be maintained all the time.

gritty sensation, blurred vision redness, and sensation of dryness in the eyes.
Layers of Tear Film

meibomian glands. It plays a main role in preventing the evaporation of the aqueous
layer.
The middle aqueous layer is secreted by the lacrimal gland.

3. Its function is to provide oxygen to the cornea, wash out debris, and have antibacterial
activity. The inner mucous layer, secreted by goblet cells maintains the overall
lubrication in order to maintain lipid and aqueous layers.
What are the Factor Involved in Effective Tear film
Three factors are involved in the effective spread of tear film.
● Normal blink reflex
● Contact between eye surface and eyelids
● Normal corneal epithelium
The normal blink rate ensures regular and even spread of the tear film on the surface of
the eye. The normal contact between the eye surface and eyelids is disrupted in
conditions like facial palsy, bell’s palsy, ectropion, entropion, thyroid eye disease, etc.
These diseases should be treated well on time in order to avoid further damage. Any
abrasion or corneal ulcer may lead to an uneven surface of the cornea, this will reduce
the even spread of the tear film.
Normal Blinking
The spontaneous or involuntary blink rate is 12 times per minute with an amplitude of
9.5 mm and a duration of 0.3s.
What are the Steps to Avoid Dry Eye
● Keep the screen at the appropriate distance of about12 inches in length.
● Make the fonts of the writing bigger and bold.
● Reduce the brightness of the screen and avoid places that can induce glare.

4. ● Windows and curtains should be closed during screen time.
