Eyes are the most beautiful part of one’s body. Not does it only adds to the beauty, it connects important veins to the brain to transmit sight neuron  signals. Some people consider glasses to be a bad addition for their outlook, and would want to replace them with contact lens instead. As much as contact lens is seemed to be a better replacement of glasses, it too demands a great care.  

Advantages and Care of Contact Lens

The lens give a great clarity to the eye sight. It helps to clear your view in rain, unlike glasses, which becomes so dusky and makes your vision poor. For people who have beauty preferences, the contacts come in multiple shaded, thus, giving them a range of colours to choose from. Apart from all the advantages that contacts hold, they demand a great care. They have an expiry date, and should not be used after the date is over, else it would become dangerous for the eyes and sight. The hygiene of contacts must also be taken care of. Usage of uncleaned or expired contact lens may result in permanent loss of sight. Even a small amount of dirt left on your lens can cause severe eye infections. Similarly, you cannot sleep with your lens on,  as it results in severe negative effects on eyes. 

For how many hours should Contact Lens be worn?

The time usage of lens depends upon the quality of lens. A good quality lens can be worn for the whole day, whereas the compromised quality lens may start to irritate after a few hours, depending upon their ability. If the lens irritate the eyes, they must be removed immediately. Even for the good quality contacts, doctors advise the users to not wear them more than eight hours continuously. 

The first time wearing of lens may cause irritation. Our eyes are very sensitive  to introduction of any external body. It may take a day or two for eyes to get used to the lens. But if the irritation intensity is great, it is advised to remove the lens immediately. One should never compromise on the quality of lens. Preferred lens material is silicon hydrogel lens, as it is very delicate for the eyes and makes more room for better oxygenation.
