Soft Contact Lenses Designs

No matter what is the condition of your vision and whether you suffer from nearsightedness, farsightedness, astigmatism, bifocal/multifocal prescription or presbyopia, there is always a suitable soft contact lens design for you. Read on to know more:

Soft Contacts for Nearsightedness and Farsightedness

Soft contact lenses as spherical single vision contact lenses can correct nearsightedness and farsightedness and are the most used contact lenses among the users of all ages. They have the required prescription curvature at all meridians to aid in accurate vision. The brands and products in demand are ACUVUE(R) Advance(TM) and ACUVUE(R) 2 (Vistakon/Johnson & Johnson), Focus(R) Dailies and Night & Day(R) (Ciba Vision), SofLens(R)38 (Bausch & Lomb), and Frequency(R)55 Sphere (CooperVision).  

Soft Lenses for Astigmatism

Soft contact lenses that are especially aimed at correcting astigmatism along with nearsightedness and/or farsightedness are known as toric single vision lenses. The lenses are designed such that the different powers in different meridians of the lens can correct the vision problems associated with astigmatism.

The weighting system of these types of lenses is also different from the normal lenses which specifically prevent the lenses from rotating on the eyes which is necessary for a clear and consistent vision.

The lens power in soft toric lenses can be described with a sphere power (sph) and a cylinder power (cyl).  

Focus(R) Toric (Ciba Vision), SofLens(R) 66 Toric (Bausch & Lomb), Frequency(R)55 Toric (CooperVision), and ACUVUE(R) Toric (Vistakon/Johnson & Johnson) are popular soft toric singlevision brands.

Soft Lenses for Presbyopia

Presbyopia can be defined as the problem of vision when it comes to focussing on near objects. This generally happens after the age of 40. The soft lenses that are used to correct the vision problems are usually bifocal or multifocal lenses which can correct presbyopia as well as nearsightedness or farsightedness. However, the vision depends upon a number of factors like the fitting of the lens and even the diameter of the pupil of the wearer. It is a common problem in bifocal or multifocal soft lenses users that they experience when they use distant vision contact lenses and reading glasses over them when they have to focus on near objects. But it is also true that to get rid of glasses, users are ready to make a bit of compromise with 100% acuity in their vision.

Acuvue(R) Bifocal (Vistakon/Johnson & Johnson), SofLens(R) Multi-Focal (Bausch & Lomb), Focus(R) Progressive (Ciba Vision), and Proclear Compatibles(R) Multifocal (CooperVision) are the popular brands.

Monovision Contacts for Presbyopia

Presbyopia can also be corrected with single vision lenses which can be spherical or toric. The prescription is such that one eye is fitted for distant and the other one for near vision. Contact lens users who are uncomfortable in bifocal and multifocal contact lenses find it easier to see through monovision contact lenses.
