Did you know that the concept of contact lenses was first imagined by Leonardo da Vinci? Since their commercialization, many types of lenses have appeared on the market. Wondering which ones to use? Your optometrist will be able to recommend lenses that match your prescription, the shape of your eyes and that will suit your lifestyle.

Soft Lenses
The vast majority of contact lens wearers use soft lenses for the sole reason that it is easier to adapt to this type of lens compared to rigid lenses because they become comfortable almost instantly. They are the simplest lenses to put on and take off. This is the option most often recommended for those who have never used contact lenses before.

Rigid Gas-Permeable Lenses
These lenses allow more oxygen to pass through than soft lenses. They might feel more comfortable for someone who experiences dry eyes on a regular basis. Since they are placed directly on the cornea, they also correct astigmatism more precisely than other types of lenses. A rigid lens wearer must take extra care of the lenses because they can be used for a long period of time. They can be kept from one to two years! These lenses usually require a few weeks of adaptation before reaching optimal comfort.

Coloured Lenses
If you want to change the colour of your eyes for a special occasion or for your everyday life, you might want to use coloured contact lenses! The opaque lenses will completely change the shade of your irises while the translucent ones will enhance their natural colour. Some lenses can even aesthetically correct abnormalities such as lack of iris, called aniridia, or a deformation of the pupil, which is called dyscoria.

Reusable Lenses (Biweekly or Monthly)
These lenses must be changed every two weeks or every month, depending on the type. They must be cleaned after every wear. To do this, simply rub and soak them in a disinfecting solution overnight. This type of contact lens is more budget-friendly for those who need them regularly, as their daily usage cost is lower than the cost of daily use lenses.

1-Day Lenses
In this case, a new pair of these lenses should be used every day. Unlike reusable lenses, they do not require maintenance at all. These contact lenses are useful for those who wear them only occasionally, for example for sports or travelling. Using a new pair each day also reduces the chance of eye infection.

Monthly Lenses
It is possible to wear these lenses during day and night for up to 30 days. They can be an interesting solution for those who often forget to remove them before going to sleep. However, it is not uncommon to experience dryness when continuously wearing contact lenses. The advice of the optometrist must also be followed carefully in order to avoid infections. Indeed, complications are much more common for those who wear lenses during both the day and night. To avoid complications, make sure to use a new pair each month and to attend the follow-up exams recommended by the optometrist.
