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.

Dear valued patient,

We take our commitment to keeping our patients and team safe and healthy inthe midst of this COVID-19 pandemic very seriously. We want to share our plan to comply with social distancing guidelines for your upcoming appointment. Please carefully read the steps below and follow our direction when you arrive. Our team will all be wearing masks and we ask that you bring one with you to wear during your visit (for everyone’s safety, we are requiring staff and patients to wear masks).

We ask patients to complete necessary paperwork online if possible. Click here to access the forms. You may also choose to text a photo of your insurance card and photo ID to the clinic at 763-537-3213.

When you arrive for your appointment, enter the main doors and wait in the front alcove until a staff member greets you. Our front desk team will ask you general health questions to rule out the presence of COVID-19 symptoms.

We are asking that only the patient enter the building for the exam. (Exceptions: Children under 18 may be accompanied by one guardian, and adults with special needs may be accompanied by one caretaker.)

When you enter the building:

Staff will ask you to use hand sanitizer and then you will complete any necessary paperwork that you were not able to complete online, and we will make copies of your insurance card and photo ID if you did not text a picture of them to us.

Prior to seeing your doctor, a technician will escort you to a pre-testing room where you will be asked to wash your hands. We ask that you follow the CDC’s recommendation of washing your hands thoroughly, for a full 20seconds, with soap and water.

Rest assured that every surface and every piece of equipment you come into contact with has been sanitized prior to the arrival of each and every patient entering our practice, and it will be cleaned again as you exit each area.

The team will be frequently washing their hands between interactions as per our usual protocol, and you’ll also see hand sanitizer throughout the practice for your use, as well.

Optical – Shopping for Glasses, Adjustments and Repairs, and Glasses Pick-up

We are scheduling appointments for all optical needs. Please call the clinic at 763-537-3213 to schedule your appointment.

When you are shopping for glasses, one of our ABO certified opticians will ask you to be seated at a station where you will discuss your needs, likes and dislikes. To ensure social distancing, the optician will bring frames to you so you can try them on at the station. The optician will continue to bring frames to you until you find the perfect pair!

We sterilize every frame a patient touches in a UV Cleaning Unit after a shopping appointment so you can be assured any frame you try on has been sanitized prior to your visit.

If you have any questions or concerns, please don’t hesitate to call us. We look forward to seeing you!

Thank you for your patience and cooperation,

Your Crystal Vision Clinic Eye Care Team
