How Progressive Lenses Work

Progressive lenses or progressive addition lenses (PALs) are the most popular multifocal lenses today, offering an effective and great looking vision solution for individuals with presbyopia (age-related near vision loss). The main advantage of progressive lenses over standard bifocals or trifocals is that they don’t have a visible line bisecting the lens, but rather a seamless and gradual change in power as you move down the lens. Rather than two or three distinct zones (for near, far and intermediate), progressive lenses offer a smooth transition of focal powers that covers the total range of clear vision from close to far and every point in between.

As we age, particularly after the age of 40, our near vision begins to deteriorate. Progressive lenses allow you to see at all distances with one pair of glasses. They start with your distance prescription (if you have one) at the top of the lens and increase as you move toward the bottom of the lens. You simply move your head position to allow you to focus through different areas of the lens. Move your head upwards to see something in the distance, hold it straight for intermediate or arm’s length vision and down for near vision for objects that are close up.
In addition to the aesthetic improvement of the lens without the line segments (which tend to make people look and feel older as well), PALs avoid the visual discontinuity or image-jump when your eyes shift from one zone to the other in non-progressive multifocals.

Adapting to Progressive Lenses

While most people adapt to progressive lenses fairly quickly (many immediately), for some, getting comfortable vision with progressive lenses can take a few days. This is normal as you need to train your eyes to look through the appropriate area of the lens and get used to the slight adjustments when you move from one area to another – especially if you move your head quickly. If you find that you are not adapting to the lenses after a few days, speak to your eye doctor- they may not be the right fit or the right option for you.

Types of Progressive Lenses

There are a number of options for progressive lenses which vary in style, price and function.

Standard PALs
Standard progressive lenses must fit to your vision needs. They can be added to frames of your choice, but you need to ensure that the frames are the right width and height proportions to grant enough space for the gradient changes in the lens. Otherwise only a small area will remain for the distance or near vision zones.

Short Corridor PALS
To overcome the issue mentioned above, there are now progressive lenses called “short corridor” lenses made to fit into smaller frames to suit a wider range of eyewear styles.

Computer PALS
Also known as “near variable focus lenses” or “office lenses”, these specialized PALs are designed specifically for computer users and other occupations that require strong intermediate and distance vision. For computer users that work at a computer for many hours, these lenses will help to reduce eye strain, eye fatigue and other symptoms of computer vision syndrome that come from looking at a computer for extended periods.

PALs for reading
Individuals who enjoy reading can opt for a pair of lenses with a larger close vision zone. Free-form lenses offer a customizable surface with a wider area for near vision.

Progressive lenses are a great option for most individuals who require multifocal or reading glasses and still want to maintain a youthful look and appearance. Speak to your eye doctor about your specific needs and lifestyle to find the best option for you.

Dear Patients,

We will be reopening our office Monday, May 18, 2020, and would like to bring you up to date with the many very important physical and procedural changes we have made to our office to assure the highest level of health and safety for our patients and staff during these very challenging times.

We have consulted with our county, state and federal officials, as well as the CDC and other healthcare professionals, to incorporate the recommended and required safety measures throughout our office.

We sincerely apologize for any inconvenience we may have caused by rescheduling or postponing your earlier appointments.

To assure the health and safety of our staff and patients, as well as minimize any exposure, we have instituted the following changes. Please read through this entire document and print a copy so you are familiar with them.

1. Any and ALL appointments and visits will need to be scheduled. This includes the pickup of eyeglasses or trial contact lenses, frame selection, eyeglass repairs, and eyeglass adjustments.

2. Contact lenses will be shipped to all patients at no charge

3. To maintain social distancing and minimize any possible exposure, we have spread out our patient schedule.

4. 24-48 hours before your appointment, one of our staff will be calling to remind you of your appointment and discuss your ocular and medical history. In addition, they will ask you standard COVID19 screening questions and answer any questions regarding your upcoming exam. This will take 5 – 10 minutes but this initial call is important to allow you ample time in our office.

Please look for and answer this call.

5. In order to save time and keep everyone on schedule, any and all medications you are taking should be listed in as much detail as possible on a separate piece of paper, emailed to our secure site: DROXENBERG@COMCAST.NET, or entered on the patient registration form on our website: WWW.DROXENBERG.COM. This needs to be completed prior to your appointment and should include all systemic medications (diabetes, hypertension, etc.) and ocular medications (eye drops, glaucoma medicine, etc.).

6. On the day of your appointment please plan to arrive 15 minutes early and call us at (717) 394-3798 when you arrive. We will return your call when you will be allowed to enter. Entry will be through the front door only unless previously discussed with our staff. Only the person with the appointment will be allowed in the office with the exception of minor children who have the appointment. NOTE: Family members and/or friends will need to wait outside.

7. We will be taking your temperature in the vestibule and anyone with a temperature of 100 degrees or higher or who is sick will be rescheduled. If you feel ill, please reschedule your appointment.

8. All staff will have their temperatures checked 2 times daily for your safety.

9. All staff will wear a facemask while in the office. In addition, all patients must wear a facemask while in the office as mandated by Governor Wolf for all PA businesses. If you do not wear a facemask, one will be provided to you.

10. There are hand sanitizing stations strategically placed throughout the office. Please use them.

11. All frames will be disinfected before and after being handled by patients and staff. Frames will not be returned to the frame display until they are appropriately disinfected.

12. All exam room equipment will be cleaned and disinfected before and after each use according to the CDC guidelines.

13. Cleaning and disinfection of our office have always been a priority and this will continue in earnest.

14. Preferred payment is by credit card or checks at the time of services but cash will be accepted.

15. We have installed a plexiglass barrier on our front desk to comply with the CDC and state guidance.

16. Reception area chairs have been separated to maintain social distancing.

17. Patients who are physically disabled will be allowed entry through the rear door, with prior approval, following a temperature check and COVID19 screening. All other patients must enter through the front door and screening vestibule.

18. Above all else, your safety and health are our top priorities. We take this responsibility very seriously and have implemented these changes in procedures to achieve this.

Dr. Oxenberg has been providing eye care to you and your family since 1990 and expects to continue for many years to come.

If you have any questions and /or concerns, please feel free to email our office at droxenberg@comcast.net or call (717) 394-3798.

We look forward to seeing you all again!

Sincerely,

Dr. Larry Oxenberg
