Buying contact lenses can be a very exciting time for a person because it changes the way they see everything. The world can be seen in a way that has little distortion, things are their correct size, and all is seen at the proper distances. In a way, it is a type of shell shock when the contacts are in and the person sees the world for the first time through them. But who invented the contact lens? Where did it come from?

Every one who undergoes cataract surgery gets an IOL (intraocular lens implant) unless there is a complication that prevents it. In the old days we did not have IOLs, and patients had to wear those thick "coke-bottle" glasses afterwards. The reason is that the cataract is actually a hazy lens. This lens is crystal clear when we are born, and every year of life adds a little haze to it. The lens has focusing power, just like the lens in glasses. If the lens has the perfect power you need, you will not need glasses. If the lens does not have the perfect power your eye needs, you have to wear glasses to see clearly. During cataract surgery, we remove that lens and therefore must replace it with a clear man-made lens to reduce or even eliminate the need for glasses.

Both have their advantages over the other and both have their disadvantages and it is important to review these advantages and disadvantages because the eyes are very important in this seeing world that requires vision for proper function. If we cannot see properly, then we easily miss things, have difficulty reading, or can become seriously injured when in hazardous conditions. This is why it is necessary to carefully evaluate the contact lenses versus eye glass debate and figure out what side you are on. Contact lenses Contact lenses certainly have their advantages, which is why many choose them over their eye glasses.

In poor light conditions, or when it's dark, the pupil dilates or gets larger. Many people with larger than normal pupils are not even aware of it.
