The aging of the lens is likely due to the free radical damage caused by ultraviolet light. Loss of accommodation is a basic measure of biological age. Can be caused by exposure to ultraviolet light. Will eventually interfere with vision. May be removed by excising the crystalline lens.
Treatment is effective with early detection and when medicine regimen is followed precisely.
In glaucoma peripheral vision is lost leaving one with ever increasing tunnel vision. Ultraviolet light exposure is greatest in situations where the sun is shinning brightly but overexposure is also possible on hazy, overcast days. Places where UV is the greatest are areas where the light may be reflected, as in off the water and off the snow. High altitudes and low latitudes are also contributing factors.
