    Monovision is usually designed for people over the age of 40 with farsightedness or presbyopia and it a treatment where the contact lens in the non-dominant eye is set for reading while the lens in the dominant eye is used for perceiving objects at a distance. Patients may endure blurred or double vision, nausea, headaches, dizziness and general discomfort during the process of adjustment. There are also some incidental symptoms that eyes may be tired quickly while reading and patients may find halos or glare around lights during night. Those symptoms may last one to three weeks, and some may even last three months. It is best to ask a doctor for professional advice.

    Monovision contact lens is used for the group of elder people between 40 and 45 who has presbyopia. This kind of contact lens provides two different lens strengths, the dominant eye has the distance lens and the non-dominant one has the nearby lens. However, there are some limitations that not suitable for everyone to wear. Firstly, you would feel loss of depth perception after wearing the monovision contact lenses. And it decreases the distance acuity because of the two contact lenses have different distance of vision. Even it's not easy for people who have night activity, especially night driving when wearing the monovision contact lenses.
