When compared to the first contact lenses introduced several decades ago, the easily fitted and worn soft lenses of today are worlds apart. Those earliest lenses were often made of hard, brittle plastic, routinely irritated the eyes, and could pop out unexpectedly. Today's popular types of Acuvue contacts, however, are made from soft, yet very strong moisture and oxygen-permeable materials. They almost never pop out, because they fit the eyeball's curvature perfectly.
In addition, they could not always provide a working correction for some eye problems such as astigmatism, or the need for bifocals. These limitations have been overcome to a large extent, however, and today's lenses reproduce clear, sharp distance vision as well as correcting nearsightedness or presbyopia. They also are much more comfortable, because the soft, flexible plastic materials used in construction bend easily, and allow a free flow of healthy oxygen.
The first conventional soft lenses evolved fairly quickly into frequent replacement lenses. While soft-lens care years ago required overnight sterilization, it was a cumbersome process, and could be easily forgotten or ignored. Early sterilizers could run out of steam, and sometimes actually ended up cooking the lenses. Today's disposable lenses, however, have eliminated the need for daily sterilization. Simply wear them for a specific time according to your doctor's recommendations.
Additionally, there are super-convenient one-day lenses available for those who would rather not bother at all with any kind of maintenance. They are made of extremely lightweight material designed to be worn only once, and never kept in solution for future use. These super-moist lenses require very little wetting during the day, and are simply replaced daily with new, freshly packaged and sterilized lenses each morning.
At the other end of the spectrum are lenses created for those with very active lifestyles. While not ideal for everyone, these lenses can be worn up to thirty days in a row without removing them at night. They are designed to allow the easy transfer of oxygen to the cornea, allowing wear during sleep if necessary. For younger people, they can almost totally eliminate the need to wear glasses.
Glasses frames today are often created by designers, and contact lenses have also entered the world of fashion. They are often used to dramatically change the eye color of the wearer. Special tints enhance the existing iris color, and opaque colors can be used to radically alter it for a complete change of appearance. They are worn by those needing vision correction, as well as people who simply want to experience a new look for the day.
For most people, the most serious complications of wearing lenses daily are simple eye irritations or blurriness. Both are usually very temporary, but if they last a while then it is appropriate to consult with your eye doctor. When compared to earlier lenses, the materials used in today's contacts make insertion, removal and daily wear nearly free from discomfort, and most people experience few of the problems early wearers used to have.
Once the eye doctor has determined that your prescription is suitable for one of the popular types of Acuvue contacts, it is very important to follow wearing instructions closely. Never keep them in the eye longer than the recommended length of time. To avoid corneal damage, do not wear them overnight unless expressly designed for that use. When worn according to recommendations, however, they can provide a visual clarity and freedom impossible to experience with glasses.
