The development of the High Oxygen-Transmissible Contact Lens, it was Leonardo who first invented them, now they become a marvel of the world

Surprisingly to most, contact lenses have had a long history of development since their design was first sketched by Leonardo da Vinci in the early 1500s. However, it was not until the early 1970s that the real benefits of this wonderful device were made readily available to most with the development of the soft contact lens. Continuing in this rich reign of historical contact lens development has been the recent development of the high oxygen-transmissible soft contact lens.

Today soft contact lenses are made from a number of plastics but chief among these is the plastic hydrogel polymer HEMA, which allows for a high water concentration in the lens - at a ratio of approximately 2:1. As they are made of a flexible soft plastic, high oxygen-transmissible soft contact lens of this nature allow the wearer to benefit from the extended daily wear available from a disposable lens. In this regard, the soft plastic allows the oxygen to pass through it, or permeate it, to reach your eye. Consequently, lenses of this type are easier to get used to because they are, overall, more comfortable to wear.

However, in order for there to be more chance of a success that the oxygen will reach your eye, you need to keep in mind the fact that the higher the level of water content in the make-up of the contact lens, the higher the chance that the oxygen can pass through. Therefore, in order for a high-oxygen-transmissible soft contact lens to really work it needs the contact lens to have a high water density.
