Nearly everyone who has cataract surgery will be given an artificial lens called an intraocular lens (IOL). These lenses improve your vision by focusing light on the back of your eye. You won't be able to see or feel the lens. It requires no care and becomes a permanent part of your eye.
Quora User, Driving since 1995. Gas is always on the right, brake is in the left in an automatic and the Middle in a manual. The brake is always the next peddle to the left of the gas.
There are actually two versions of engine braking. For a typical car, engine braking would be when you let off the gas and natural forces (like gravity and the push back from the engine) slows the speed of your vehicle. When the gas pedal is released, a type of vacuum is made in the throttle, creating a braking effect.
