Using contact lenses, especially for those who have worn glasses for many years, can be very relieving. They make our lives much easier, but careful attention is needed both when putting them in and while wearing them.
There are many cases where we either wear monthly lenses longer than we should—because we didn’t wear them enough during the month after purchase—or wear them for many consecutive days without removing them. These are common mistakes, often due to our busy daily schedules. However, wearing contact lenses that have expired can cause serious problems.
Have you ever wondered what happens when we wear contact lenses longer than recommended?
The cornea of the eye needs oxygen, just like all organs of the human body. This oxygen comes from the tears and the air. Expired contact lenses can often limit the oxygen reaching the cornea, which in turn can lead to eye infections. Another risk factor is wearing lenses at night while sleeping. Sensitivity to light and severe pain are just some of the milder effects; there is also a high risk that lenses may scratch the corneal surface, contributing to infection in the resulting wounds. This can happen when lenses are left in for many hours or not properly maintained.
Other common mistakes in contact lens use include:
Exposing lenses to water.
Even though it sounds simple, it is not. Water contains many components that can damage the lens, and later, when we place it in our eye, we may injure the eye or allow microorganisms from the water to enter and cause infection.
Failing to regularly replace lens solution.
The same solution should never be used twice. From the first time we remove our lenses and place them in the solution, they “leave behind” all the bacteria and dust from the day. Therefore, it is crucial to replace the lens solution after each use.
Rinsing the lens case with water.
The lens case must be rinsed, but this should be done with lens solution, not water. After rinsing, the case must be dried thoroughly with a clean towel or paper and left to air dry completely before closing.
Using saliva to fix uncomfortable lenses.
Saliva, like water, contains pathogens and bacteria that should never come into contact with the eye.
Continuing to wear lenses that cause discomfort.
A very common mistake is insisting on wearing a lens even after it first causes discomfort. This practice should be avoided; it is better to wear glasses to prevent irritation or injury to the eye.
Putting lenses in after applying makeup.
A frequent mistake, particularly among women, is inserting lenses after putting on makeup. It is better to insert lenses before any cosmetic application to avoid any product entering the eye.
Rules for the correct use of contact lenses:
- Wash hands thoroughly with soap and water and dry them before handling lenses.
- Do not wear lenses in the sea or in the shower.
- Never store lenses in plain water.
- Check the expiry date and replace lenses when it has passed.
- Recommended daily wear is approximately 8 hours.
- Replace the lens case every month.
- Always carry glasses, so that at the first sign of discomfort you can remove the lenses and prevent potential injury.
