Eye Contacts – An Eye-Opening Guide

There are just a few online resources that offer a one stop guide on eye contacts. This makes the search for quality contacts even harder. It’s great that you happen to get to this page. You’ll have everything you need to know from the basic to cosmetic contacts right here.

Eye contact lenses come in eight varieties. They are: soft, hard, rigid gas permeable, daily disposable, silicon extended wear, bifocals, toric and colored.

The Soft Lens

This type of lens is produced from plastics which allow oxygen to pass through it. This gives the wearer a comfortable feel. Some soft lenses may even have UV protection. However, this lens does not permit prolonged use. It is categorized as a disposable contact lens. Most of these lenses would only last from 2 to 4 weeks which is healthy and safe for the wearer. Bacterial growth, infections and protein build-up is averted.

The Hard Lens

If soft lenses are permeable, hard lenses are non-permeable to oxygen. This means prolonged use and ignorance of the scheduled replacement can irritate or damage the eyes. With that said, prescription of this type of contacts are only limited to some special purpose that the eye doctor sees fit. With the risks involved, a number of lens manufacturer have discontinued hard lens production.

The Rigid Gas Permeable Lens or RGP

This was designed to replace hard lenses. It has both the good qualities of soft and hard lenses. It is durable yet permeable. It does not easily deform plus enhances vision.

The Daily Disposable Lens

This lens is good for a day only. This is more hygienic than any other contacts as new lens are used each day. Secondly, it is not difficult to track when the next replacement is due. This is perfect for wearers who have abnormally dry eyes or those who have low tolerance for contact cleaning solutions.

The Silicon Extended Wear Disposable Lens

This lens was manufactured out of a new material which gives it a 30-day use. The material is also safe against protein build-up and dry eye irritation.

The Bifocal Lens

Presbyopia sufferers would like how this lens works for them. It acts as if it was a bifocal eyeglass. It can correct both farsightedness and nearsightedness. The vision is clearer. One could choose between soft and RGP bifocal contacts.

The Toric Lens

These are good for astigmatism sufferers. It is produced from the same material that other contacts are made of. It comes as either soft or RGP lens. It resembles bifocal contacts as it can repress astigmatism attacks and correct myopia or hyperopia.

The Colored Lens

Colored contacts use tints to make it more visible when handled, enhance the natural eye color or modify the eye color. There are varieties of this lens that reduce glare and improve contrast which is perfect for sports, outdoors or any active lifestyle.

Opaque tints are used to change the natural eye color. This is used largely for commercial and theatrical purposes to make a dramatic and even hideous effect. The wild eyes used in “The Exorcist” or the cat eye effect in “Cat Woman” are examples of its cinematographic application.

Of course when checking for eye contacts never forget to inquire about the price. You would be able to weigh the product better by knowing the quality and the cost. However between the two, prioritize the quality.
