No. You should avoid exposing your contact lenses to water, as it can contain harmful bacteria and microorganisms that may stick to your lenses and increase the risk of eye infections. Always remove your contacts before showering or participating in any water-related activities. Also, never use water to clean or store your lenses.

Apply makeup before inserting lenses to avoid transferring residues. Remove lenses before makeup removal to prevent irritation to your eyes.

Contact lenses should always come first. This is because makeup products often contain oils that can remain on your hands even after washing, which can cause lens fogging or eye irritation. Additionally, cleansing agents can come into contact with your eyes.

Always handle your contact lenses with clean hands to ensure safety.

No. Contact lenses sit directly on the eyes, whereas glasses sit slightly away from the eyes. This difference in positioning can lead to different prescriptions. Additionally, prescribing contact lenses requires specific information about the base curve and diameter of the eyes. Therefore, when ordering contact lenses, you must obtain a prescription specifically for contact lenses from an eye doctor.

Is it okay to nap while wearing contact lenses?

It’s important to remove your contact lenses before napping, even if you’re using extended wear lenses. Always consult an eye doctor to determine if extended wear lenses are suitable for you.

The cornea, where the lens sits, needs oxygen. When your eyes are closed during sleep, oxygen intake from the air is reduced, and contact lenses can further restrict this flow. This increases the risk of infection and vision issues.

Remember to always take out your contact lenses before falling asleep!

How to tell front from back of contact lenses?

When using fortnightly or monthly lenses, it can sometimes be hard to tell which side is the front and which is the back during cleaning and storage.

To distinguish them, place the lens on your fingertip and check the edge shape. If the edge curves naturally like a bowl when viewed from the side, it’s the front side (normal).
If the edge is slightly turned outward, it’s the back side (inside out).

The image provides a visual guide on how to determine if a contact lens is correctly oriented. The left side shows a correctly oriented contact lens, labeled with a red "O: Correct." The lens has a smooth, bowl-like shape. The right side shows a contact lens that is inside out, labeled with a blue "X: Inside out." This lens appears to have flared edges and a flatter shape.

In this article, we’ve covered several common FAQs, but you may still have other questions like “What should I do in this situation?”.

If you have any uncertainties, be sure to thoroughly read the contact lens and solution instructions, keep your lenses and case clean at all times, and handle them correctly to protect your eye health.

If you still have unanswered questions, consult an eye doctor for guidance.
