⚠️ Important Notice
This article is for informational purposes only.
The iTeraCare device is not approved as a medical treatment for any eye condition by regulatory bodies such as ANMAT, FDA, or EMA. For any vision problems, always consult with a qualified ophthalmologist.
Do not discontinue or replace any medical treatment indicated by your doctor.
Visual health is a fundamental part of overall well-being.
Millions of people seek to complement their eye care with healthy habits and wellness technologies that support conventional medical treatments.
In this context, some iTeraCare users report feelings of well-being when using the device in the periocular area.
In this article we explore what current research says about Terahertz frequencies and biological tissue, and how iTeraCare can be used as a wellness supplement — always under professional supervision.
Terahertz (THz) frequencies occupy a band of the electromagnetic spectrum between microwaves and infrared light.
In recent years they have been the subject of exploratory research for their interaction properties with biological tissues.
Research published in the Journal of Infrared, Millimeter, and Terahertz Waves has explored the effects of THz radiation on cells and tissues under laboratory conditions.
It is important to clarify that these studies are preliminary and conducted mainly in vitro — outside the human body — and do not constitute clinical evidence of therapeutic effect on eye diseases.
Some iTeraCare users report that using the device on the forehead and temple area, strictly following the manufacturer’s instructions, generates sensations of relaxation and general well-being.
It is important to note that:
– iTeraCare is not indicated nor approved as a treatment for myopia, hyperopia, astigmatism, presbyopia, color blindness, conjunctivitis, glaucoma, or macular degeneration.
– Color blindness is a condition of genetic origin that currently has no known medical treatment that cures it.
– Glaucoma and macular degeneration are serious conditions that require specialized ophthalmological follow-up.
– Any use of the device near the eye area must be carried out following the manufacturer’s instructions and with prior authorization from an ophthalmologist.
These habits have solid scientific backing for general eye care:
REGULAR VISUAL REST
The 20-20-20 rule: every 20 minutes of screen time, look at an object 20 feet away for 20 seconds.
Recommended by the American Academy of Ophthalmology.
NUTRITION AND VISION
Foods rich in lutein, zeaxanthin, and vitamin A, spinach, carrot, egg, are associated with retinal health according to the American Journal of Clinical Nutrition.
SUN PROTECTION
The use of UV-filtering lenses reduces the risk of cataracts and macular degeneration, according to the World Health Organization.
REGULAR OPHTHALMOLOGICAL CHECK-UP
Early detection is the most important factor in conditions such as glaucoma, which may present no symptoms in its early stages.
Terahertz frequencies are an emerging field of research with interesting preliminary results.
iTeraCare can accompany your general wellness routine, but it does not replace an ophthalmological consultation or medical treatment for any visual condition.
If you have questions about your visual health, the first step is always a consultation with a specialist.
