• Blinking helps to moisten the eye and keep dust out.

Normal value of NCT is typically between 10-21 mmHg.

• Normal value of NCT (Non-Contact Tonometry) is usually between 10-21 mmHg.

• NCT is a common method used to measure intraocular pressure in the eye.

• Values outside of the normal range may indicate conditions such as glaucoma.
