If you are planning to buy contact lens for the first time, there are only two reasons for it:
1. For correcting your vision impurity.
2. For cosmetic purposes.
In both the cases you need to know a few things about contact lenses. A contact lens is made of glass, plastic or polymer which is shaped to fit over the cornea of your eye. They help in improving vision in the same way as glasses do, but without visibly changing your appearance.
In certain conditions they have been found to be effective where glasses fail to bring any results, like Keratoconus, which is a disease in which cornea progressively, thins out in to a cone shape resulting in a distorted vision.
When buying contact lens keep certain factors under consideration which will help you decide in choosing the type best for you:
• If you are likely to wear them occasionally then go for soft lenses.
• If you need comfort or you suffer from dry eyes choose soft lenses.
• For frequent or daily users, the silicone lenses are a better choice as they allow more permeability to oxygen and prevent any sort of infection from occurring in the eye.
If you are planning to use contact lenses for cosmetic purposes, it is better to get advice from an opthamologist for any underlying disease which might get aggravated, as eye is a very sensitive organ.
Consider buying UV protective lenses which will not only give you a great look but at the same time provide you protection from the outdoor sunlight and the glare of oncoming traffic lights at night.
Another point of key importance is the care of your lens. You will have to clean, wash, disinfect and properly store your lens as a matter of routine. Some things have to be done on daily basis and some on weekly. But the important thing to realize is that your proper care will determine its life and your own health. If you don’t want to indulge in maintenance or find it too hard to follow, there are disposable lenses which are discarded after single use.
So when you go for your purchase, be absolutely sure of what you need to buy.
