Prolonged exposure to high levels of infrared radiation could lead to burns and cause eye problems, including cornea and retina damage, cataracts and injuries to the eye lens. In addition, infrared radiation can cause pain to the skin of a person in close contact with it.Know More
Most infrared radiation is not visible and may affect a person without his knowledge. Similarly, some radiation is neither hot nor colored, making them difficult for people to detect and avoid.
In the electromagnetic spectrum, infrared rays are just below visible red light. Many objects, including lamps, flames, stars and other warm items, emit these rays. They are most commonly used in mobile phones, in remote controls for TV sets and in other short-range communication devices. In addition, physiotherapists use infrared technology to help the healing of athletes' injuries.
Modern weapons have infrared detectors that are designed to spot targets, particularly at night. Although occasional exposure to these rays is not enough to cause danger, everyday contact can cause long-term health problems. Employees working for companies involved in the mass production of lasers and heat lamps have a higher risk of experiencing adverse effects due to exposure. These rays can disrupt body cells, penetrate DNA and cause cancer. Those who are vulnerable are advised to wear protective gear.Learn more about Optics & Waves
Physical trauma, diabetes, hypertension, excessive ultraviolet light exposure and exposure to radiation may lead to early-onset cataracts, as stated by the Eye Care Institute. More than 50 percent of all people have developed cataracts by age 80.Full Answer >
Astigmatism is a visual disorder that causes blurred vision due to the irregular shape of the cornea or uneven curvature of the lens inside the eye. The cornea and the lens are responsible for focusing light entering the eyes, allowing images to be clear.Full Answer >
Possible side effects immediately following lens implant surgery include light sensitivity, a feeling that something is in the eye, hazy vision and bloodshot eyes, and long-term risks include vision loss, vision abnormalities in low-light situations, increased pressure inside the eye, clouding of the cornea or natural lens, and retinal detachment, according to the U.S. Food and Drug Administration. Short-term symptoms typically diminish over the four-week period following surgery. Infection is a possible side effect of any surgical procedure.Full Answer >
Cataracts are removed after the eye surgeon makes an incision in the patient's cornea and then carefully removes the clouded lens. Before surgery, topical medications are used to dilate the pupil and numb the eye. The patient may also be sedated.Full Answer >
