Common Misconceptions About Eye Drops (artificial tears)
01
Is continuous use of eye drops (artificial tears) the only solution to relieve chronic dry eyes?
02
Are eye drops (artificial tears) with preservatives good or bad?
iTEAR uses non-invasive technology to stimulate the external nasal nerve to promote natural tear production. It has been clinically proven to effectively relieve dry eye symptoms!
How to use iTEAR?
For first time use, charge the device for 2 hours,(please note that as iTEAR is not yet activated, no indicator light when charging) , then press and hold the power button for at least 5 seconds to turn it on.
- For use, press the power button and the vibration tip will begin to vibrate. The vibration will pause for 0.5 seconds every 10 seconds as a reminder.
- Without pressing, gently place the vibrating tip to the area between nasal cartilage and the bone of each side of the nose.
- During the application, it is normal if you feel slight soreness or it makes you sneeze.
- Continue for 30 seconds on each side of the nose. It is recommended to use in both morning and evening, or as needed.
iTEAR Product Features
Restoring your tear production
Clinical study showed that after 30 days of use, the level of basal tear production has significantly increased by a mean of 56%¹; thus restoring the ability to produce natural tear to relieve dry eyes from the root, or helping to reduce the dependence on artificial tears.
1
Improvement in tear film stability
Clinical study showed after using iTEAR for 30 days, the tear film stability has been effectively improved (TBUT*+33%)¹, and may help reduce rate of tear evaporation, relieving symptoms associated with corneal dryness.
*TBUT = tear break up time, is a direct measure of tear film stability and refers to the time taken for the first dry spot to appear on the cornea after a complete blink.
2
Non-invasive vibration technology
With the unique vibration frequency, iTEAR is applied to the area between nasal cartilage and the bone of each side of the nose to induce tear production. In clinical study, it has shown to instantly increase tear secretion by a mean of 3.7 times¹ upon first use.

2Question: How to charge iTEAR?
iTEAR may be charged via a Type-C charging cable. An indicator light at the base of the device displays the charging status. (The following information is about charging after first time activation. For charging before first time use, please refer to "Question 1: How to start iTEAR?")
‧When charging, an LED light turns to a steady yellow.
‧When charging is complete, an LED light turns to a steady green.
‧When battery is low, an LED light turns to a flashing orange light when pressing power button.
Please note that iTEAR cannot be used while charging.

About the Usage
1Question: How is iTEAR different from other vibration devices?
Although there are many vibration devices on the market, not all devices have undergone clinical trials to prove their efficacy, nor are FDA-approved2.
Using non-invasive vibration technology, iTEAR uses a unique vibration frequency to stimulate the area between soft and hard cartilages of the nasal cavity. It has been clinically proven that after 30 days of use, the level of natural tear production is significantly increased by 56%1, thus restoring the capability of natural tear production to relieve the root cause of dry eyes, or help to reduce the dependence on eye drops.

2Question: How to find the right location to place the vibration?
For first time use, it is recommended to place the vibration tip on the back of the hand to feel the vibrational intensity. The vibration tip should be gently placed to the soft and hard cartilages of the nasal cavity without pressing it. Continue for 30 seconds on each side of the nose. It is recommended to use in the morning and evening, or as needed. During use, it is normal to feel slight itchiness and to sneeze.
3Question: Is there a limit to the number of times it may be used per day?
It is recommended to use for 30 seconds on each side of the nose, in both morning and evening, or as needed.
It has been clinically proven that after 30 days of use, the level of tear evaporation reduced, thus improving tear film stability (TBUT* 33%)1, and relieve symptoms associated with corneal dryness.
It is recommended for users to undergo an eye examination after 30 days of use. Please consult your physician or a professional for advice.

4Question: Can iTEAR be used alongside medications?
Under normal circumstances, as iTEAR is not a drug, it may be used alongside medications. But if you are undergoing other treatments, please consult your physician or a professional for advice.
5Question: Can I use iTEAR if I have had surgery on my nose, such as Botox or hyaluronic acid fillers?
We recommend consulting your physician or a professional before use.
