What are contact lenses and why to choose them over spectacles?

You have eye prescription, you don't like wearing spectacles? For some, wearing glasses is not preferable always, but they can't avoid them as they have eye power and they need them ON to see everything clear, all the time!

They are so thin and light weight, that they are easily stuck onto your eyes wet surface (wet - our eyes/cornea have tear layers over them, this is to provide oxygen and keep them lubricated, it get's formed and cleared everytime we blink, this is why blinking is so important. Some people complaint of having itchiness or excessive eye watering, which is a natural response to one's dry eyes. Consult your eye care practitioner if you have mentioned symptoms. Dry eyes are caused due to, less blinking, this happens when people use digital devices or are under air conditioned rooms for long time).
