Q: I am a 28 years old male having a cylindrical power in the left eye (-1.25) and normal (-1.5) in the right. I want to start playing cricket again and want to use contact lenses. On visiting the optical shop they asked me to wear -1.5 eye power lenses in both the eyes. They also told me that if cylindrical power exists we need to add half the power to it. Is it safe to wear lenses with a cylindrical power?

A:Cylindrical power is caused by slightly oblong (like an egg) shape of the front of the eye. When you wear contact lens the gap between the cornea (front of the eye) and the contact lens is filled with tear fluid and makes front surface round and regular so you don't need cylindrical correction specially true with small powers.
