1. 1. Use a clean case and fill it with fresh contact lens solution—never reuse old solution.
2. Never use tap water—it contains bacteria that can cause serious eye infections.
3. Keep the case clean by rinsing it with solution and air-drying it.
4. Replace the case every 1-3 months to prevent contamination.
5. 💡 Warning: Storing lenses in tap water can warp, damage, or contaminate them, making them unsafe to wear. Always use a proper contact lens solution for safe storage!

If contact lens is inside out, it won’t fit as well on your eye’s surface and will make you feel uncomfortable. Your contact lenses will move around a lot when you blink.

METHOD 1. SIDE CHECK

Place the contact lens on your fingertip. Look at the shape of the contact. When it is correct, your contact lens will have the shape of a cup. The edges will curve upright. If your contact lens is inside out, it will have the shape of a rimmed bowl.

METHOD 2. TACO TEST

Pinch the contact lens in half to form a taco shape. If the edge looks like a taco shell, then your contact is facing the correct way. If the shape resembles a soup spoon, it is inside out.
