Contact lens is a soft plastic plate placed in the cornea of human eye. It works same as that of an eyeglass, but is more advantageous than the traditional eyeglasses. Contact lenses are light-weight and weigh almost nothing, they are fully transparent. When a person wears a contact lens on the cornea region of the eye, it cannot be distinguished. Some contact lens manufacturing companies use tints of color on these lenses, so that they can be visible while cleaning. Since, a contact lens has direct contact with the cornea; there are certain possibilities of eye injury (if certain precautions are not taken). The eyeglasses are safer in such cases, but if a person faces any kind of accident, then also his eyes can get totally damaged by the broken glass pieces of the spectacle. The contact lenses are much better in such cases.

How Can You Tell if a Contact Lens is Inside Out?

Whether you are a new contact lens wearer or you have been using them for years to correct your vision, you may be wondering how can you tell if a contact lens is inside out. If you suspect you may be wearing your contact lenses incorrectly or they just feel uncomfortable, here are some ways you can determine this to avoid the problem in the future.

Look at the Lens

Before placing the lens in your eye, hold it on the tip of your index finger and look at it carefully from the side. Is it shaped like the letter “U” or it is flared on the sides, like a soup bowl? The correct shape of a soft contact lens should be like the letter “U”. If it’s shaped like a soup bowl, then it’s inside out. Some people also recommend the “taco test” whereby you gently squeeze the lens so that the edges touch. If they touch completely, then the lens is right side out. If the edges flare out and don’t touch fully, then it’s inside out. Simply flip the lens around and it will be positioned correctly for wearing.
