Contact Lenses - How To Choose The Right Ones

Different Types of Contact Lenses

With the development of a range of different contact lenses types, it can be hard to figure out which one is right for you. There is no concise answer as to which type is better, but there are varieties that may be better suited to your lifestyle. Following is some information that can help you decide what type to get.

Let’s begin with: What do contact lenses do? Contacts are small vision-correcting lenses that are in "contact" with the eye. They are designed to correct refractive errors and maintain eye health. They float on the tear film layer on the surface of the cornea. Modern contacts are much more than just small glass lenses that sit on your eyes. However, they work in much the same way as ordinary glasses - which refract and focus the light so that objects appear clearly. Because the lenses attach to the tear fluid on the surface of the eye, they move naturally with your eye movements. This is just one of the benefits of contacts over glasses.

Not all contact lenses are the same type. They are available in different designs, designed to fulfill different purposes. These designs can vary from "model" to how often you change them - e.g. daily or once a month. They also meet different needs, such as contacts for astigmatism, myopia, and so on. The contacts are available in different strengths or "diopters". If you wear contact lenses, look at the packaging or in your prescription. There you will see a plus or minus signs, followed by numbers. Without going into too much depth, these signs express the shape of the lenses. Different shapes correct different vision problems. Toric lenses, which are weighed at the bottom, help correct astigmatism. Spherical lenses, which are identical all around, help to correct myopia and farsightedness. There are also monovision, bifocal, and multifocal contacts.

The first aspect to consider is that all contact lenses can only be worn for a limited amount of time. Daily disposable contact lenses last only one day, while rigid gas permeable (or RGP) lenses last over a year. However, there is currently no contact lens type that can last forever. Another unique trait of daily disposable lenses is that they require no maintenance. As a rule of thumb, you should note that the longer you can wear the lenses, the more maintenance, and care they require. 

The technical history - contact lenses

Contacts and the idea behind them have a much longer history than what most people suspect.

The history of contact lenses and the improvements that await them in the future are exciting topics, as most of us have some form of vision problem. Vision correction is a chronic need that is everywhere. In the United States, about 168.5 million people use some form of corrective aid such as glasses or contacts. That's more than half the population of the United States! More and more people are using contacts to improve their vision. Since 1991, the number of contact lens wearers has increased by 4% per year. Users' reasons for choosing lenses instead of glasses vary from active lifestyle choices to purely cosmetic ones.

Among many other of today's modern conveniences, Leonardo da Vinci described the idea of ​​contact lenses as early as 1508. Renee Descartes developed this further when he sketched a protruding contact lens in 1636. Later - in 1801 - the scientist Thomas Young became the first to wear a contacts, which was attached to his eye with wax!

Yes, a lot has happened in lens comfort since then ...

In 1971, the first soft contact lens was officially launched, thus taking us into a new era far from previous hard lenses. The next major breakthrough in contact lens technology came in 1988 with the launch of the first disposable lenses. It would then take another eight years for the introduction of one-day lenses in 1996.

Daily Contact Lenses

These contacts may only be worn once, which comes with both benefits and consequences. Since they are changed daily, you don't have to worry about disinfecting or storing them overnight. This low maintenance aspect also makes them great for people who only wear contacts for special activities, such as sports or nights out. Dailies are also considered the safest type of contact lens since there is no bacterial build up that can lead to infection or eye problems. However, they can be more expensive and you must be sure to replace them every day. 

Monthly Contact Lenses

Weekly/Bi-weekly and monthly contact lenses are also often made of soft materials. These contacts must be removed at night, sanitized, and stored in solution before use the next day. Extended wear contact lenses are a rather new product that can be worn for extended periods of time, even allowing wearers to sleep in them. This type of contact lens is made with silicone hydrogel technology. Silicone hydrogel technology allows more permeability to the eye, which lessens the chance of health risks associated with wearing contacts for an extended period of time. 

Hard Contact Lenses

Another way to loosely categorize contacts is by seeing if they are Hard or Soft, with some contact lenses being a hybrid of the two. Soft contact lenses are much more common, are pliable, and need to be constantly hydrated. These contact lenses are more easily put in and taken out and considered more comfortable than Hard lenses. Soft lenses are also not worn for a long period of time, so there is a smaller chance that they will be infected. One of the most popular types of Soft lenses is silicone hydrogel contact lenses


Hard contact lenses are not as common and are more often used by people with complex vision problems such as astigmatism, irregular corneas, and more. These lenses can be worn for years if cared for properly, but are harder to fit and generally less comfortable. Therefore, when choosing lenses, it's important to consider the trade-off between the comfort and convenience of soft lenses and the long-lasting properties of hard lenses. 


Colored contact lenses

Have you ever wished your eyes were a little bluer than their natural color? Now you can have it - even if you do not need vision correction. There are coloured contact lenses that enhance, or even change, your eye color. This includes plano lenses; lenses without powers. There are even black contact lenses that you can use for your next Halloween costume. However, since contact lenses are medical devices, you should talk to an optician before testing this type of joke lens. After your eye exam, you can buy your coloured contact lenses NZ at SmartBuyGlasses!
