Types of contact lenses
Soft contact lenses
These contact lenses are made of a gel-like watery plastic known as hydrogels. These lens types are thin and very comfortable to wear, any user can adjust to them instantly.
Silicone hydrogel lenses
These are an advanced version of hydrogels introduced in 2002. They are more porous than regular hydrogel lens and allow more provision of oxygen for the cornea.
Gas permeable lens
They are a hard lens type but they are porous and allow for oxygen to pass through so that they can be worn rather comfortably than other hard lenses.
Hybrid contact lenses
Hybrid lenses are made to provide comfort which rivals soft lenses. They have a rigid gas permeable zone, but despite these features they are not much popular, maybe because they are expensive to replace soft lenses and they don't fit that easily.

Disposable soft lenses
Water absorbing lenses were first designed back in the early 1960s and now they are more than popular among lens users.
Soft lenses have a water content which ranges from 50 to 80 percent. They normally cover the whole of the pupil and some of the white part of your eye.
You can wear disposable lenses for a day or for a whole month, it varies. Consisting of water content and designed to be thinner they provide comfortable wear. You will find different disposable lenses which can be worn for a day only and be disposed off after use while there are also long term disposable lenses which needs to be disinfected after every use. Disposable contacts can be prescribed for everyday use or long term wear, depending on the brand of the lens and why you need to wear it.
Disposable contacts never last for a lifetime rather they have an expiry and have to be disposed off after that. Each brand of contact lens has a exclusively suggested replacement schedule based on the capability of the lens to allow provision for oxygen and to shed proteins from the surface.
Daily wear contacts
Daily wear contacts are designed to be worn for the whole day, basically around eighteen hours and so, and are crafted such that they are comfortable for hours on end. They are available in reusable and disposable categories, meaning that they can be used several times and disposed after one time use.
Individuals most often use these lenses for parties and stuff like that, they are available in different colours for events and parties, you can also buy coloured contact lenses Halloween in this category.
One must remember to put them off before sleep, otherwise they may cause damage to your eye's health
Extended wear contacts
Daily wear contacts have to be removed prior to sleeping but extended wear contacts can be worn while awake or asleep, they are designed as such.
One downside of initial extended wear contacts is the lack of oxygen flow and the distress that can come from long term wear, including dry, itchy eyes. With technological advancements experts are working on finding the right solution these lenses so that one can wear them comfortably for long hours and prevent it from depositing dirt under the lens
Different colour variations in lenses
There are opaque lenses available which are coloured and designed to cover the eyes completely and appear to change the colour of your eyes. These are mostly used for contacts for parties and Halloween.
Other colour type includes the enhancers which are styled such that they enhance the natural colour of the eyes, as the name suggests, they do not change the colour of one's eyes.
Lastly you have visibility tinted lenses which, unlike enhancers and opaque, do not hide or mask the colour of the eyes. They have a slight tint added to them so they are visible from the case or when they accidentally fall down.
