Lens Handling And Placing

There are various options of contact lenses available for those who want to make a switch from eyeglasses to contacts

. In general, these types of contact lenses have both good and flip sides, which are the main purpose of this writing.

One of the most basic types is rigid gas permeable contact lenses that are made of flexible plastic. This type of contacts provides clear vision but also requires a longer period of adaption. Wearers need to wear rigid gas permeable contact lenses as constant as possible for most comfort.

Daily wear contact lenses belong to soft lenses, which are also made of flexible plastic. The advantage of this type is that these daily wear lenses do not come out easily thus suit people with an active life. However, a flip side is that they require more frequent replacement.

Unlike daily wear, extended wear lenses can last for a long time. In most cases, these lenses are approved to wear for seven days without removal. Since these lenses last for quite a long duration in the eyes, complications may occur. In addition, extended wear lenses are also provided in disposable version, which is encouraged to be worn for at least six days before being discarded.

Most types of contact lenses come in a similar manner of packing. In most cases, six lenses are packed together so that all the lenses have sterility, which is called multi-packs. Customers should be aware of some tips while opening the package. The package of the lens should be shaken in order to make sure whether they are floating in the solution. After that, peel off the covering to get to the lens. Whats more, the package had better to be placed on a flat surface for lens stabilization.

When it comes to lens handling, it is quite necessary to form a habit that either the left or right lens should be handled first every time. This habit is effective in preventing the wearer from mixing up the lenses in the future. Removed from the pack, a lens should be checked for cleanness. Moreover, a lens that is turned inside out should be avoided.

After proper checks, the lenses can be placed in the eyes. A contacts wearer should use his hands to pull down the lower eyelid and lift up the upper lid before applying the lenses. Then release the eyelids and blink. The lenses will adjust themselves into an appropriate position.
