It is a good thing that presbyopes are given more options when it comes to vision correction. Aside from the usual standard bifocals, presbyopes can also have the newer progressive spectacle lenses. Unfortunately, only a few people are aware of these contact lens options.

Available in Hard and Soft Contact Lenses

Both multifocal and bifocal contacts are available in hard and soft materials. The hard or gas permeable lenses offer superior optics with lesser complications. However, hard contacts are less comfortable to use. On the other hand, soft lenses do have the advantage when it comes to comfort. It is now available in silicone hydrogel material, which permits more oxygen to enter the cornea compared to the hydrogel lenses.

In addition to these, people can also make use of contacts with their reading glasses. Although these things are not primarily made to work perfectly with each other, people can still use contacts for distance vision and apply reading glasses over the contacts for near vision tasks. This is also an easy transition especially for people who have worn contacts for many years. Nevertheless, it can get a little annoying for some to take their reading glasses on and off all day.

Learning More about Monovision

Monovision refers to the use or practice of wearing one contact for distance vision and the other for near vision. This is actually a lot easier for an eye doctor to prescribe and it also easier to find the best contact that works. Nevertheless, not all people can adapt to using monovision. This will depend on the type of vision used by the person every day and as well as his or her ability to adapt easily with vision changes.

Monovision makes it difficult to for the person to use his or her  eye that has contact for near in viewing distance vision and vice versa. Nevertheless, some people can easily adapt and ignore the other eye that is not utilized for a particular distance. One of the downsides of monovision is that it cannot provide a perfect vision to the user. This is evident especially when it comes to viewing intermediate distances. Some people would even experience problems with their depth perception while using monovision. Nevertheless, monovision is a lot cheaper compared to buying multifocal lenses.

What is the Modified Monovision?

Modified monovision is a term that is used to define the special tactics used to enhance vision at a particular distance. This can include several things such as one single vision lens in addition to a multifocal lens. Aside from this, it also uses different add powers on each eye and it also combines various D & N lenses.

What are Multifocal Soft Contacts?

Most soft contacts made to correct presbyopia come in two different styles. One is called Aspheric. This type of soft contacts is very similar to the progressive lenses since it blends the different powers together across the lens. This vision is also simultaneous and it is necessary for the eyes to find the right spot to clearly see at a particular distance. The other design of soft contacts is called concentric ring. This is also classified as part of the aspheric category. However, concentric rings do have defined zones that can alternate between near and far vision. These contacts may have at least 2 to 5 rings. The center portion of the lens can be the far or near prescription. This will depend on the brand of the contacts and as well as the prescription of the eye doctor.

What are GP Multifocal Contacts?

GP lenses are considerable more effective especially for people who have already worn this type of lens. Success rates can be measured up to 75% and can be associated with its optical quality from the use of gas permeable lenses. Just like soft contacts, the GP lenses are also categorized into two. The first one is also called Aspheric. This design is also a type simultaneous vision lens; however, the progressive power change is placed at the back of the lens. Aspheric GP lenses are highly recommended for early presbyopes that have lower “add” power. This also works well for people with more intermediate distance needs. This is also highly recommended to people who are always working in front of the computer.

The other type of GP lenses is called Translating. This type of lens makes use of a weighted bottom that aids in orienting the lens properly. This allows better distance and near vision to the user. In other words, it works exactly like a bifocal glasses lens since it has one power on top and another at the bottom of the lens. The lower lid is utilized to stabilize the lens especially when looking down through the near part of the lens. It requires users some time to adapt with its effects, but generally it can provide a very good vision.

Choose an Experienced Doctor

Using bifocal and multifocal contact lenses requires more experience and time to fit compared to the single vision lenses. Because of this, it is necessary to find a doctor with specialty in using this kind of lens. These professionals are able to help clients find the best contacts that will benefit them the most. Nevertheless, it is important to understand that these lenses will never provide a perfect vision to all distances. It is also necessary to always have realistic expectations.
