According to a recent study, when the surface temperature of the eye and eyelids drops to 86 degrees Fahrenheit (30 degrees Celsius) this could cause or worsen dry eye. The cold temps outside your body cause the oily substance secreted by lid glands to become too thick to spread properly onto the eye surface.
Macular degeneration, also known as age-related macular degeneration (AMD or ARMD), is a medical condition which may result in blurred or no vision in the center of the visual field. Early on there are often no symptoms.
Macular degeneration is a formidable challenge to patients, their doctors, and our society as the costs for delivering state-of-the-art care increase. Macular degeneration, also called age-related macular degeneration (AMD or ARMD), affects the macula, which is the central portion of the retina of the eye. Our central vision (what you see directly in front of you rather than what you see at the side [or periphery] of your vision) is dependent on a healthy macula.
