There are many different kinds of contact lenses available, all of which need to be prescribed by an eye doctor. If you want to purchase contact lenses, you need to talk to your eye care provider.
In order to give you a prescription, your eye doctor will perform a complete examination of your eyes, try different contact lenses on your eye to see which is the best fit, rest your vision, and give you instructions on how to wear your contact lenses. Here are the most common types of contact lenses:
Soft contact lenses
Soft contact lenses are made from flexible, soft plastics that are breathable and allow oxygen to reach the cornea. They are super easy to adjust and are more comfortable than other types of lenses. The newest soft contact lenses are made from silicone-hydrogels, a material that provides maximum passage of oxygen to your cornea.
Rigid gas permeable (RGP) contact lenses
Rigid gas permeable contact lenses are durable and resistant to dirt buildup and give a better and clearer vision. They are more economical and last much longer than soft contact lenses.
They are super easy to use and resistant to tears. However, they are not that comfortable, and it might take you a few weeks to get used to wearing them.
Extended wear contact lenses
Extended-wear contact lenses are ideal for those who need to wear lenses continuously and overnight. They can be worn for up to six nights and 30 days. They are soft, comfortable to wear, and flexible. Extended wear contact lenses from www.contactlenses.co.uk are made from materials that allow oxygen to reach your cornea.
However, not all extended-wear contact lenses are designed to be worn while sleeping. Length of wear depends upon the lens type, and you should consult your eye doctor, who will evaluate your tolerance for overnight wear. It is important to test your eyes before purchasing your contact lenses.
Disposable contact lenses
The majority of contact lenses are disposable, which means they need to be discarded after one use. They have a daily wear disposable schedule, and a brand new pair of lenses is used every day. Some soft contact lenses are frequent/planned replacements.
This means they can be worn for up to 30 days before having to be discarded. When you remove your lenses, make sure you disinfect them and clean them with the cleaning solution before wearing them again.
This type of contact lens is usually used for cosmetic purposes. They allow you to change the color of your eyes and are often worn by actors and actresses for their different roles. They also come with different patterns and can be used on Halloween.
In a nutshell
Your eye doctor will recommend the type of contact lens best suited for you. Wearing contact lenses that are not fitting and failing to observe proper hygiene can cause eye infections, injuries, and other complications.
