Correcting and Clarifying Your Vision: An Optometry Blog

A Guide to Contact Lenses

by Troy Simmmons

Contact lenses were invented in the late 19th Century, and since then, they have become an increasingly popular eye care solution for those with poor vision. Despite the fact that they have been around for so long, many people do not have an understanding of the different contact lenses available. The modern world of eye care offers a range of different contact lenses. If your optometrist has recommended that you wear an aid to improve your vision, you may be wondering about the different types of contact lenses which are available and which one would be best suited to you. Below is a guide. 

Daily disposable contact lenses

As the name suggest, this type of contact is supposed to be worn for a day then disposed of. This means that they can be very convenient for people who have busy lives, as you will not need to carry out the time-consuming cleaning procedures associated with other contact lenses. Their ease of use also makes this type of contact lens ideal for those who are new to wearing them.

Two-weekly contact lenses

Two-weekly contact lenses are similar to daily disposable lenses but can be worn for up to two weeks before they need to be deposed of. However, they should still be taken out at night and stored in a sterile solution to prevent any contamination which could lead to the development of an eye infection.

Monthly contact lenses

Monthly contact lenses represent the next step up from two-weekly lenses and, as the name suggest, can be worn for up to a month. The major advantage of investing in monthly contact lenses is that they can save you money, as you will not need to buy as many lenses as frequently compared to the other options. Some monthly contact lenses are specially designed to be worn even when you sleep.

Rigid gas permeable contact lenses

Rigid gas permeable contact lenses allow for the transfer or oxygen to the surface of the eye, which promotes eye health and removes the need to remove the lenses at night. The rigid design means that the lens retains its shape, providing a sharper image when worn but still has some flexibility, which means that this type of contact is still comfortable to wear.
