Eye Care: The Construction and Characteristics of Contact Lenses

People make choice to wear contact lenses rather than eyeglasses for a variety of reasons. For some, vanity is guiding influence, while others don’t care for weight of glasses as they rest on face. Still others prefer to use eye care products that can’t be as easily broken. Loss, too, is a consideration, since most people don’t remove their contact lenses and put them aside when they’re away from home environment, whereas glasses have often been removed and inadvertently left on a table or some other handy surface.

There are a few basic types of contact lenses which are available to public, first of which is hard contact lens. These are made from a strong polymer plastic and are easy to keep clean since they don’t absorb foreign material from either eye or environment. As a result of firmness of product, however, they can take time to adjust to and shouldn’t be left in eyes overnight. This will cause cornea to become oxygen deprived – and cornea needs oxygen flow to remain healthy. Vision is usually crisper with this type of contact lens, as opposed to softer variety of lenses.

Another common type is soft contact lens. These are made from a softer plastic – called hydrogel – which makes them more comfortable to wear, but are less durable than those of hard lens line. The water content in soft contact lenses is higher than that of hard lens - from 25% to 79% - allowing a better flow of oxygen to cornea. Due to fact that material is highly porous, infections and eye irritation are more common. This happens when dust, protein and bacteria cause contamination of lenses, which are pressed against surface of cornea.

Hypnosis Way of General Indications of Deceit

When subject is changed, he’s in a better, more relaxed mood. The guilty wants subject changed; innocent always wants a further exchange of information. • He does not become indignant when falsely accused. While he is being accused liar will remain fairly expressionless. The liar is more concerned with how he is going to respond than he is with accusation itself. • He uses such phrases as “To tell you truth,” “To be perfectly honest,” and “Why would I lie to you?” • He has an answer to your question down pat, such as giving precise detail to an event occurring two months ago. • He stalls by asking you to repeat question or by answering your question with a question. “Where did you hear that?” “Could you be more specific?” or even repeating your question back to you, at an attempt at sounding incredulous. For example, “Did I sell you a puppy with a heart condition? Is that what you’re asking me?” • What he’s saying sounds implausible, such as “During past ten years, I have never used a specific racial epithet.” • He offers a preamble to his statement starting with “I don’t want you to think that…” Often that’s exactly what he wants you to think. Whenever someone makes a point of telling you what they’re not doing, you can be sure it’s exactly what they are doing. Such as, “Not to hurt your feelings, but…” • He implies through a form of denial. You hear, “He’s having marital problems, but it has nothing to do with his wife’s new job.” What’s first thing you ask? “What does his wife do?” Suddenly you’re in exact conversation that is “supposed” to have no bearing on facts. • He uses humor or sarcasm to defuse your concerns, rather than responding seriously. • He offers you a “better” alternative to your request when he is unable to give you what you originally asked for. Before you accept someone at his word that he has something better to offer, first see whether he has what you originally asked for. If he doesn’t, then you shouldn’t believe him. • All of his facts relating to numbers are same or multiples of one another. Watch out when facts, figures, and information have unusual similarities.
