You've donned your Christian Lacroix designer suit, your Jimmy Choo designer sling back shoes and grabbed your Prada designer handbag. You're doing lunch with your friend at the trendy Nobu restaurant where you intend to have the four calorie designer salad consisting of two olives, an iceberg lettuce leaf and half a tomato.

Of course, spring will be here soon and it just won't do to be seen in last season's white skin so after lunch a trip to the sun beds to top up with that orange tint you think suits you so well is essential.

Now picture a totally different scenario.

You open your wardrobe and can't tell which outfit is Dolce and Gabbana and which is Top Shop. Feeling around for your shoes, are those Manolo Blahnik or Tesco gardening shoes? You think you've got it all together when you search for your handbag but are unable to tell the difference between Gucci and Dorothy Perkins. White sticks do not come in designer styles but does it really matter now?

After being driven to the restaurant, you have to put all your faith into the kitchen staff when you order your calorie quota in the form of egg white omelette and low fat water and trust they don't give you the full fat version.

To avert the above disaster, looking after the health of your eyes is an absolute must. By all means, wear the designer clothes and kit yourself out with designer accessories. However, be sure not to overlook the designer sunglasses. Make sure they block at least 99% of UV rays and you could avoid the above state of affairs.

As well as wearing designer sunglasses, ditch the ridiculous faddy diets and eat a healthy, balanced diet rich in vitamins and minerals if you want to avoid the damage the sun can do to your eyes and save your sight.

By all means enjoy the sun, we need the vitamins we absorb from the rays, but always use protection. Sit in the sun, wearing your designer sunglasses and eat fruit and vegetables to your heart's content. Nobody ever became obese through eating too many fruit and vegetables.

In fact, eat a diet rich in yellow and orange fruit and vegetables, along with green leafy vegetables to include lettuce (not the iceberg variety), carrots, mango, spinach, peppers, oranges, broccoli and any others that take your fancy and you can reduce your risk of developing age-related macular degeneration later in life.

Nuts, seeds and dairy products are also sight savers. It is the Lutein and Zeaxanthin in these foods that will help you in the fight against blindness. It's all very well seeing celebrities in the press, stepping out of clubs in the middle of the night, with their micro bodies and huge designer sunglasses but do they know what they are doing?

Wearing sunglasses at night makes you a fashion victim, not a trend setter. It makes you look silly, as does a woman having the body of a twelve year old boy. These celebrities are doing untold damage to their bodies and the health of their eyes by their extreme diets and unhealthy practices.

So, continue to enjoy your top level fashions, enjoy your designer restaurants but make sure you enjoy your food, eat enough to fill you up and above all, enjoy your designer sunglasses.
