The A to Z of Contact Lenses – G to L

Glass Contact Lenses – the early contact lenses were made out of heavy duty blown glass. Whilst the contact lenses were wearable, they were uncomfortable and difficult to fit and remove.

Hard Contact Lenses – more rigid and more difficult to get used to, hard contact lenses offer the most benefits to sufferers of eye problems such as astigmatism. This is mainly due to the fact that these contact lenses are stiffer than soft contact lenses, providing more support to re-mould and re-shape the eye’s cornea)

Intraocular Contact Lenses – developed firstly in the late 1940’s, intraocular contact lenses are surgically fitted to the person’s eye as a long lasting, permanent contact lens. Whilst it may seem using intraocular contact lenses would be a ‘cure’ to any vision problems, there is the chance that something could go wrong later on after the fitting, meaning they are generally only used after the wearer has already gone under lengthy eye surgery.

Johnson and Johnson – probably the most popular and recognisable name in the contact industry, Johnson and Johnson are leaders in their field. Developers of a variety of contact lenses, Johnson and Johnson provided the world with the very first daily disposable contact lenses.

Keratitis – caused by a variety of different factors, such as over exposure to bright light, keratitis is the term for the result which occurs – an inflamed cornea. This can be rectified or at least controlled by using darkened, tinted contact lenses.

Leonardo Da Vinci – often accredited with the first steps towards corrective vision using contact lenses, Da Vinci carried out some detailed research and produced a variety of drawings showing the way light enters the eye and the different ways it is refracted back out, depending on the state of the persons lens and cornea.
