The lifespan of a pair of contact lenses

Unlike spectacles, pairs of contact lenses have an expiry date and need to be renewed regularly.
However, the lifespan of a contact lens depends on several different parameters.
Here's what you need to know about how long contact lenses last and what defines their durability.

Their renewal frequency

The lifespan of contact lenses depends on the type of lens replacement, which is often chosen according to the person's lifestyle.

Daily contact lenses

Single-use and disposable, daily contact lenses are very handy and easy to use in everyday life.
They are accessible to everyone, from beginners to experienced wearers, as they do not require any care.
For this reason, they are particularly popular with busy people and amongst young people.
Daily lenses are often used for one-off occasions, such as a special event or a night out.
However, daily lenses are more expensive than other types of contact lenses.
Furthermore, this type of lens requires regular purchase since it only lasts for one day.

Monthly contact lenses

Also available as bi-monthly lenses, monthly contact lenses are still the most popular among contact lens wearers.
In fact, this type of contact lens remains the most prescribed and best-selling contact lens in the UK.
Monthly lenses are cheaper than daily lenses, which can be a significant advantage for people who wear their lenses every day.
On the other hand, these contacts require daily care to be preserved for thirty days.

Yearly contact lenses

The most durable contact lenses on the market are the yearly ones, which are also called conventional lenses.
This type of contact lens is economical since they are only renewed every one to one and a half years.
Yearly contact lenses are known for their wearing comfort and their ability to correct any type of visual disorder.
However, these contact lenses require rigorous care and daily attention to keep the devices intact and efficient throughout the year.

Contact lens care

With the exception of daily disposables ones, all contact lenses require everyday care.
The life span of contact lenses therefore also depends on how much attention is paid and whether or not they are regularly cared for.
Indeed, contact lenses must be handled with care on a daily basis so that they're not deteriorated and to prevent harming the eyes.
In particular, impeccable hygiene is essential to ensure that they are not soiled when held in hand.
In addition, they must be stored every day in their case in a suitable solution.
Finally, they should not be worn for more than eight to twelve hours a day, depending on the wearer's habituation.
Contact lenses must also be removed before going to sleep and in certain circumstances, such as when they may come into contact with water.
Only if all these care rules are followed will contact lenses last a reasonable amount of time.
