The Eye and How It Works

Eyes collects light from the surrounding environment. The light passes through the clear cornea and the clear fluid (aqueous humour) of the front chamber of the eye (anterior chamber). By the actions of the dynamic coloured diaphragm, the iris, the amount of light entering the eye is controlled. The light is then focused onto the retina (detecting layer), by the lens. The lens is held in place by zonules (these suspensory ligaments are string like structures that radiate out from it like the spo...

It is a sticky subject… a difficult one to approach as a non smoker to smokers, a tricky addiction behaviour to break down and beat, a powerful chemical addiction, and a social hot potato.  Let’s start at the very beginning…Botanically, tobacco plants are from the same family as tomato, potato and deadly night shade (Atropa belladonna) which is the original source of atropine, use...

Eye Floaters

The posterior segment or back chamber of the eye is far bigger and constitutes the bulk of the eye. The total distance between the tip of the cornea and the tip of the back of the eye is typically 21-24mm.This chamber contains a gel-like substance akin to egg white, called vitreous humour. It is made up of about 1% protein fibres and hyaluronic acid and around 99% water.
