Clinical studies have shown increasingly poor quality of life using the fluorescent easily induced cataracts , especially elderly accelerate the progression of cataracts .
In general , the quality of qualified energy-saving lamps and fluorescent lamps release UV will not harm human health , but the poor quality of the lamp is energized, the mercury atoms inside the lamp will release the human eye can not see ultraviolet light , ultraviolet light body hit the wall the phosphor coating , and then reconverted to visible light. According to Professor Rui Lian well as the dean of Ophthalmology, Choi said, " excessive ultraviolet radiation is one of the accepted senile cataracts cause ." Tseng Choi Lim explained that , under the influence of UV , phosphorus ions may be combined with the aging of the lens of calcium ions forming insoluble calcium phosphate , which leads to hardening of the crystal and calcification. Therefore , cataract patients living in the tropics , sea fishermen , as well as the highlands , the cause of most and UV-related .
Answering the phone too often can lead to cataracts ? Eye Institute recently has domestic authority , for the first time experimentally confirmed: electromagnetic microwave can damage the eye lens produced answering the phone , damage cell communication connection. Professor Lian Tseng Choi said lens of the eye is one of the organs of the body most susceptible to microwave damage . Use the phone a long time, would cause irreversible tissue damage . Suggest that you do not burn "mobile porridge" , the longest talk time try to control in half an hour.
Patients can eat vitamin C foods
How to prevent the onset of cataracts ? Professor Lian Tseng Choi recommendations to prevent cataracts progress , winter diet health is very important. Usual tea, tannic acid in tea contains a substance with antioxidant response role , often drinking can prevent cataracts ; eat foods rich in selenium, zinc -rich foods , but also beneficial to the prevention of cataracts. Scientific research found that when the body content of selenium deficiency , cataract incidence was significantly improved. High zinc content in the lens , people suffering from cataract lens significantly reduce the amount of zinc . In addition , people with cataracts in the elderly should be appropriate to eat more foods rich in vitamin C , such as: tomatoes, dates, fresh green vegetables.
Also , do not miss the best time for cataract surgery because of cataract wait too mature , it is likely to cause all kinds of ophthalmic complications , but also easily lead to retinal eye exam questions can not be found in other older age groups , such as age-related macular degeneration, diabetic retinopathy lesions .
