Overnight Vision Correction  using small custom-designed contact lenses is an exciting new treatment for short-sightedness - where distant objects appear blurred - that offers all the benefits of laser surgery but without the surgery. The lenses are only worn overnight while sleeping then removed each morning after which the wearer has perfect natural vision all day long until reinserting the lenses at night. Even better, latest research indicates that Overnight Vision Correction can stop a short-sight prescription from getting worse once lens wear has started which is of particular importance for children who can experience significant eyesight deterioration throughout adolescence. And a further enhancing factor for optimising distance vision has now been confirmed - diet can also play an important role.

However, instead of thinking in terms of eating carrots as a way of ensuring healthy eyesight, some specific nutrients that are contained mainly in the leafy dark green vegetables, such as kale, spinach, Swiss chard and collard greens are most beneficial for the structure of the eye. These nutrients are lutein and zeaxanthin which accumulate in the lens of the eye and in the macula of the retina where they function as macular pigment. The lens of the eye is where cataracts form and the duo may protect against the development of age-related macular degeneration (AMD) which is the major cause of blindness in older people. So as well as Overnight Vision Correction  contact lenses, a daily serving of these less popular vegetables would seem to be in order for good eye health.

It is believed that the two nutrients offer protection through their roles as blue light filters and antioxidants. Though information on dietary content for lutein and zeaxanthin is limited, an intake of about 6 milligrams per day has been associated with protection against AMD. Kale, spinach, Swiss chard and collard greens have 7.5 to 12 milligrams of lutein plus zeaxanthin per half cup of cooked vegetable so a daily serving would meet this requirement. For children in particular, getting them to eat such healthy vegetables is never easy but the long term benefits could be huge. Equally, whilst glasses are often the first response when a child is diagnosed with short-sight, choosing Overnight Vision Correction  contact lenses instead offers an effective correction modality which also stops short-sight worsening and provides many lifestyle benefits which glasses cannot match.
