Daily 3-minute red light exposure could improve aging vision
The non-invasive light therapy only improves vision in older patients, typically over the age of 40 Credit: Pixabay. No one is spared from the decrepitude of old age. However, not all our tissue and body parts age equally. The retina, for instance, ages faster than the rest of the body due to its high energy requirements. Don’t book an optometrist’s appointment just yet, though. According to a new study, daily red light therapy may slow down ocular degeneration or even improve eyesight. The non-invasive technique only takes three minutes and consists of shining deep red light at a specific wavelength into the dominant eye. Researchers at University College London tested the therapy on 12 men and 12 women aged 28 to 72 who had no prior history of eye disease. After an initial assessment of the participants’ cone and rod sensitivity, the researchers flashed a ‘deep red’ light beam from an LED at a wavelength of 670 nm. The therapy was administered for three minutes a day over the course ...
