What is Cholesterol - It is a type of fat - lipid - made by the liver in the body.Without it,the body will not function properly.This makes cholesterol essential and vital for good health. It is also part of the outer membrane of every cell in the body.It acts as an insulator to nerve fibres - which carry chemical signals around the body - travel properly.

* Not doing any exercise or regular physical activity may increase low density lipoprotein (LDL) and conversely decrease high density lipoprotein (HDL).

* Food that have trans fat, meaning that they contain hydrogenated fat, e.g. fast food, spreads, cakes, pastry, margarine, some types of biscuits.

* Generally, cholesterol levels rises as we age.Men are more likely to have a higher rise that women.

* Obesity or being overweight can cause low density lipoprotein (LDL) to increase and conversely decrease high density lipoprotein (HDL).

This scenario can obviously play out when you’re in your own home or walking a city block too, but we’re talking about the fact that it’s constant exposure to air-borne particles that poses the problem. Similarly, chemicals or vapors in the air can also cause irritation and if you instinctively rub your eyes, you again risk damage to the cornea.

On the other hand, it is possible that contact lenses might help to prevent injuries in the same way that glasses do, by protecting the eye from an airborne substance. Obviously, neither contact lenses nor glasses can replace proper protective devices. In fact, the argument seems moot if protective shields or safety glasses are worn as a matter of course.

An office situation certainly doesn’t usually have the caustic chemicals and noxious gases that some manufacturing or processing plants carry, but there are some conditions can make wearing contact lenses uncomfortable (at best) and damaging to your eyes (at worst).
