Contact Lenses at Night – Can You Sleep With Contact Lenses?

Just close your eyes for a moment – and it has turned into a nap. Many contact lens wearers are familiar with this situation. If sleep is short-lived or if sleeping with contact lenses is an exception, this is usually not a problem. Nevertheless, after a short sleep you can see why it is not recommended: The eyes are dry, in worse cases they are bright red and the contact lenses have attached themselves to the eye. They’re difficult to get off. It can cause irritation or infection. Some low quality and cheap colored contact lenses can also cause irritation. It is important to verify the colored contact lenses prices and go for only genuine and credible brands of contact lenses such as Bella, Dahab and Freshlook contact lenses in Pakistan, Dubai, UK and USA.

The night: resting phase for the eyes

Your eyes need a break to recover from wearing contact lenses. The cornea is not supplied with oxygen by blood vessels, but by blinking – oxygen gets into the eye – and through the tear film. When sleeping with contact lenses, the eye is closed twice, by the lens and the eyelid. In addition, a so-called biofilm, a mixture of residues from the tear film, is deposited on the contact lenses during the course of the day. Germs and bacteria feel good here, so you should always adhere to the recommended wearing times for your contact lenses and clean the lenses regularly.

Day and night lenses: the 24-hour contact lenses

What are day and night lenses?

In contrast to other lenses, you can wear day and night lenses permanently for a period of 30 days (day and night monthly lenses). They consist of highly oxygen-permeable silicone hydrogel, which allows incomparably much more oxygen to reach the eyes than conventional lenses. Oxygen can easily reach the cornea through water-filled pores in the lens matrix. Thanks to their low water content, they bind moisture and prevent the eyes from drying out, the natural tear film remains intact.

Special features of day and night lenses

✓ Very high oxygen permeability
✓ Integrated moisture storage
✓ Special surface technology

What are the advantages of day and night lenses?

The maximum wearing time for conventional contact lenses is between 10 and 14 hours. Day and night lenses exceed this wearing time many times over and can remain on the eye permanently. Most day-and-night lenses are offered in the form of weekly or monthly lenses . This results in a wearing interval of up to 30 days.

At the same time, permanent lenses have a relatively low water content. Moisture is optimally bound by the lenses, so that your dehydration is effectively counteracted. The natural tear film and the nutrient balance are not impaired.

With day and night lenses, the absolutely necessary daily cleaning is no longer necessary. However, if you can, you should also clean these lenses regularly to avoid irritation to the eye. After the specified wearing time has elapsed, simply take a fresh pair of lenses. You can also save the time of putting on and taking off. These lenses are also suitable, for example, for people who are allergic to care products. They are an advantage when traveling to countries with poor hygienic conditions, as well as when working in shifts or on standby duty.

Who can wear day and night lenses?

Basically there are no restrictions for day and night lenses. Nevertheless, it is particularly important to ask your ophthalmologist or optician for advice and have your eyes checked. It is important that there is enough tear fluid. If your eyes are dry or sensitive, you should refrain from wearing them permanently.

Optician advice necessary: Before you decide to use permanent lenses, you should have your eyes checked by an ophthalmologist or optician.

He can tell you whether your eyes are even suitable for wearing day and night lenses. A prerequisite for the use of permanent lenses is the availability of sufficient tear fluid. Anyone who suffers from very dry and sensitive eyes should therefore switch to another type of contact lens if possible.

What must be taken into account with day and night lenses?

Continuous wear of contact lenses increases the risk of infection significantly. Regular checks by an ophthalmologist or optician are therefore very important. If you notice a change in your eyes (redness, itching, foreign body sensation), remove the lenses immediately and contact your optician or ophthalmologist. Long-term wear should be avoided for people with dry eyes.
