Contact Lenses may be various types:
Reusable contact lenses – which can be reused, rather wear once and throw away. It must be clean before use again.
Disposable lenses – it is used once and unsuitable for repeated used. It doesn’t need cleaning or disinfecting.

Extended-wear lenses – they are specially designed for wearing over night. You may check up your eyes frequently if you use this type of lens.
No matter what types of lenses you use you must clean your hand and disinfect the lens with an appropriate solution before using it. Reusable contact lenses need special care before and after using as it prevents harmful organisms building upon it. Don’t use disposable lenses more than once because they are designed to use only once, otherwise it will cause harm to your eyes.A recent study shows that, disposable lenses are used more than they should be used and also one and half time longer than recommended. Soft contact lenses are packaged in a small container which is filled with fluid. This fluid may be contaminated if it stayed for a long time. So before use, wash and rinse it with new solution.

Now a very popular new trend that is to use contact lenses in Halloween and other festivals. With a vampire costume people use lenses like veined and bloody eye, swirling eyes, red or green eyes, make a shape of cats pupil or kaleidoscope eye, etc. In these cases people use them without a valid prescription and without consulting a doctor. Most of these lenses are collected from local street vendors, from fashion boutiques and beauty supply stores with a little amount of money. So they are risky and un-hygienic. Fashion contact lenses are different in size to fit your eyes. If this does not fit eyes properly, then serious eye damage like corneal infection, decreased vision, conjunctivitis, and scratches on the cornea and in some cases blindness may occur. So avoid these cheap lenses. Consult with your doctor, he will give you a valid prescription with brand name, lens size, and expire date.
