On Tuesday's Backchat, we're talking about a recommendation for people of all ages to have their eyes checked regularly.

The Hong Kong Ophthalmological Society and the College of Ophthalmologists Hong Kong have urged residents to get checked more often, citing a 50 percent increase in the condition known as macular degeneration over the last decade.

Although degenerative eye conditions tend to affect those over 50 more often, younger people have high rates of myopia, which carries attendant risks. Last year, a survey conducted by the Chinese University revealed that 66 percent of Secondary 3 pupils had some form of myopia.

How serious is the situation? How often should we check our eyes? What about young people? Is too much time spent in front of computer screens partly to blame.

After 9:45, we'll be hearing about a study into knee pain among the elderly.
