Dk/t value : Oxygen transmissibility of a contact lens. In general,the higher  these values are, the better is the oxygen transmissibility of the lens. The high level of oxygen flow to the cornea is important as it improves wearing comfort and longer term tolerance

Water content : Contact lenses with a lower water content dehydrate less on the eye than do lenses with a high water content, so they could be better for people with dry eyes. Contacts with a high water content usually have a higher oxygen transmissibility. Therefor they are more suitable for longer wear.

Silicone Hydrogel lens is combining the advantages of lower water content lenses and high oxygen permeability.So it contains less water and delivers more oxygen to the eye(up to 6 times) than traditional hydrogel lenses.

The base curve (BC) is a part of your contact lens prescription. It relates to the curvature of your eye and typically is a measurement in the range 8.0 to 9.0. Your eye doctor or optician measures the curvature of your eye during your contact lens exam and chooses the base curve for your contacts appropriately.

A contact lens prescription is very different than an eyeglass prescription. In addition to the lens power, your contact lens prescription contains several other pieces of information related to the size of the lens. These will include base curve, diameter, power. Toric and multifocal contact lenses also contain more numbers specific to those types of lenses.
