You’ve all heard it before. “I’m nearsighted,” or “I’m farsighted,” and possibly even “I have an astigmatism”. All of these conditions are types of refractive errors, which is a type of vision problem that can make it hard to see clearly. In fact, uncorrected refractive error is one of the top two reversible causes of blindness in the US, along with cataracts. In this blog post, we will delve into the world of refractive errors, shedding light on myopia, hyperopia, astigmatism, and presbyopia.

Exploring Contact Lens Options

Just as we have 3 main options for glasses to see far and near (two separate glasses for distance and near, the dreaded bifocal, and a progressive addition lens), there are 3 main options for contacts as well.

Distance Contact Lenses with OTC Readers: This option is likely the easiest to do, but also probably the most annoying. Here, each eye will be prescribed a contact lens with the distance prescription only. You will be able to see clearly in the distance, but to read you will have to put on OTC reading glasses over the contacts. Many people feel this defeats the purpose of contacts, since you will have to put on glasses throughout the day anyways.
Monovision Contact Lenses: Monovision involves using a contact lens prescription for distance vision in one eye and modifying the prescription to allow for near vision in the other eye. This technique allows the brain to adapt and rely on the appropriate eye for the desired distance while suppressing the other eye. While some individuals find monovision comfortable and convenient, it may take time to adjust to this method. The benefit of monovision is that it is not a special contact lens (as opposed to the next option), it is just a special technique.
Multifocal Contact Lenses: Multifocal contact lenses are designed with different zones that correct both near and distance vision simultaneously. These lenses provide a transition between the prescription strengths, allowing for clear vision at varying distances. These sound great! The solution to all our needs, why would anyone choose one of the other options? Well, the catch is you give up some clarity in the distance for your near vision, and some near clarity for your distance vision. It is a compromise, and your vision will not be crystal clear.
