Dear Patients,

We are pleased to inform you that our office is now resuming our regular business hours for appointments. Of utmost importance to us is to continue to provide exceptional eye care in an environment that is safe for our patients and entire Monji Optometry team. We have taken great measures to prepare and implement COVID-19 safety protocols guided by resources from the Center for Disease Control (CDC), the American Optometric Association (AOA) and the California Optometric Association (COA).

We want to share our new safety practices and let you know what you will expect when you come to our office.

  • Our front door will remain locked and only opened to those with appointments. To limit the number of people, all patient encounters will be by appointment, including glasses pickups, adjustments and repairs. Our schedule has been adjusted to allow spacing of people in any given area in our office.
  • We ask that adult patients arrive alone for an appointment. Minor patients may be accompanied by one adult.
  • If you are new to our office, to help us be prepared for your arrival we ask you to submit the “Patient History Form” found on our website under “Patient Forms” before your appointment. Please don’t forget to bring your latest eyeglasses and/or contact lenses.
  • Our staff and patients are required to wear masks. When you arrive, you will be asked COVID-19 screening questions and your temperature will be taken by a non-contact thermometer at the door. If your temperature is over 100 degrees, we will reschedule your appointment.
  • Upon entering, you will be immediately directed to wash your hands. We are practicing safe distancing and ask that you mindfully keep a 6 foot distance between other patients.
  • Plexiglass barrier shields have been placed at our reception desk and tables for eyeglass frame selection to allow safe interaction between you and staff. Protection shields have also been outfitted on examination instruments.
  • Our staff has been trained on CDC procedures to diligently keep touched surfaces, instrumentation and overall office clean and disinfected following each patient and regularly throughout each day. This includes disinfecting eyeglass frames.

We look forward to seeing you soon. Best regards for your continued health and safety!

Multifocal Eyeglass Lenses

Multifocal lenses technically refer to any lens that provides more than one zone of corrective power and would therefore include bifocal, trifocal and progressive lenses. Multifocals are designed for the many individuals over 40 who struggle with presbyopia – the age-related near vision loss that requires us to use eyeglasses for reading and focusing on objects in our near vision. The multiple lens powers enable you to correct for near and distance vision with one pair of glasses.

Bifocal Lenses

Bifocal lenses are divided into two powers, one for distance vision and the second for near vision. Bifocals are created in a variety of designs with different sized and shaped viewing segments for near and far vision. While bifocals provide good distance and near vision, they are lacking in corrective power for intermediate areas, which is what has led to the development of trifocal and progressive lenses.

Trifocal Lenses

Trifocal lenses provide an additional lens power zone for intermediate vision (which is typically about an arm’s length away).

Some people are bothered by the visible lines where the lenses are divided in bifocal and trifocal lenses. In addition to aesthetics (the lines have become a sign of presbyopia which many associate with growing old), the harsh divisions in the zones can cause a distortion in the object you are viewing (an image jump) when you switch your gaze from one power to the next.

Progressive Addition Lenses (PALs)

Progressive lenses were designed to eliminate the “image jump” that results from the distinct zones in bifocal and trifocal lens design. By providing a smooth progression of many lens powers across the lens, PALs allow for clear vision near, far and every distance in between. Further, similar to natural vision, they just require a slight movement of the eye, rather than the whole head, for you to see through different lens powers. The smooth transition also eliminates the visible lines present on the other lenses which many view as tell-tale signs of age-related vision difficulties.
