Why is blinking so important?

Every time you blink, you restore tear film across the surface of your eye. Light needs to pass through your eye smoothly. If your tear film is broken up, your vision is not clear. Tear film also acts as a barrier, protects your cornea and provides nutrition for the underlying structure.

Why do you experience dry eyes when using the screen for long?

When you’re concentrated on near work, you blink less. The average blink rate is 8-21 blinks per minute. Studies show that individuals blink approximately 60 percent less when using a computer.

This decrease in blink rate may be a result of serious concentration on the task at hand, or a relatively limited range of eye movement.  

When you blink less, your tear film is replenished less frequently and evaporates more quickly, causing ocular discomfort such as blurred vision, dry eyes, light sensitivity, watery eyes or a stinging sensation.

Unfortunately, there is no cure for dry eyes. However, you can still manage its symptoms. Here are 3 tips to avoid dry eyes or relieve your dry eyes:

 Tip 1: Adjusting your environment

Whether you are working in the comfort of your own home or clocking in hours at the office, the lack of moisture in your surrounding environment can cause irritation to the eyes as its surface starts to dry out. Having a humidifier near your workspace would be a great asset as it adds moisture to the air, thus providing better air quality and keeping your eyes hydrated!

Also, while using your computer or electronic gadgets, remember to adjust the brightness of your computer screen to match the light intensity of your surrounding environment to reduce eye strain.  

Tip 2: Applying Eye Drops and Using Eyelid Wipes

Artificial tears, also known as eye drops, help in maintaining eye surface moisture by providing lubrication to the eye.
