London: How can your weight affect your eyesight?
Obesity directly affects sight loss, so if youre overweight or just worried about your sight, log hrs (GMT)
It is common knowledge that expanding waistlines are linked to life-threatening conditions like diabetes, heart disease and cancer. But many of us are unaware that obesity is also linked to blindness and other serious eye health issues.
Excess body weight can cause damage to blood vessels in the eye – linked to the onset of glaucoma and diabetes. Studies have also shown people with a high body mass index (BMI) tend to have low macula pigment density and are therefore at greater risk of suffering diseases such as AMD (age-related macular degeneration). Likewise, too much alcohol, too much smoking, and even too much time at the computer screen contributes heavily to losing your eyesight.
According to official figures almost one in four UK adults are obese (23% in 2006), expected by the government to hit one in three adults next year. However many Brits are unaware that they even class as obese and are therefore putting their eyes at risk.
