I Broke a Mold During Lens Production

The Q-2100 Lens system utilizes digital free form crown glass molds during the lens production process.  There is an infrequent possibility that a mold may break during production. Use the following tips to diagnose the reason.

Mold Breakage During the Demolding Process

Possible Cause #1: Mold was directly placed into the soaking solution before one mold was separated from the mold assembly and while still hot. This can cause thermal shock to the mold.

Solution: Demold one of the molds from the mold assembly prior to placing in the Q-Soak solution

Possible Cause #2: Improper technique when using the demolding tool

Solution: The operator needs to pry (not twist) the molds apart with the proper Optical Dynamics demolding tool. If the operator twists the demolding tool the corners of the tool may have stressed the mold to break or chip.

Mold Breakage Inside the Post Cure Chamber

Possible Cause: The mold assembly may not have been processed in a timely manner.

Solution: Ensure that the mold assembly is immediately placed into the Post Cure chamber after the initial does of light in the Main Chamber.

Is it All About Index?

Simple Answer: No

It’s easy to get swept up in the excitement over a single number: higher index must be better. The simplicity is enticing. As with many technical topics, the reality is that a single performance aspect doesn’t provide enough information to judge true product quality. The idea that a lens with a certain index of refraction is a dead product or the next great thing just isn’t correct.

The More Technical Answer: Still No

If you’re into numbers, beyond index you also have to look at Abbe value, surface smoothness, processing-related deviation from target curves, required center and edge thickness (both for safety and the requirements of the frame it’s going in), lens power, your patient’s tolerance of chromatic dispersion, their eye movement patterns, the conscientiousness and equipment quality of the lab you’re using, etc. If you think it’s a lot to digest, imagine what it’s like for a patient trying to make the right decision.

Back To Simple: What’s the Wearer Say?

If you don’t want to spend the rest of your life trying to understand the minutia of every new lens that comes out, ask the people that have experience with the product. Optical Dynamics lenses have been judged by wearers and experts as some of best lenses they’ve encountered. Whether it’s a single vision or multifocal lens, people are impressed with the clarity and ease of patient adaptation. In the end, that’s really all those technical details are trying to convey anyway. Instead of using a bunch of time trying to decide if “the next great thing” is really that great, using a proven lens that wearers like can be safer and simpler.

The less simple explanation for the high praise we’ve received is that our lenses have exceptionally smooth surfaces, they precisely replicate the digital curves machined into our molds, and they are made from a lightweight, high Abbe polymer. Since the process eliminates the grinding and polishing steps normally used to make a lens, there are far fewer opportunities for machine or operator issues to cause optical problems.

A Fly In the High-Index Soup

The vexing thing about high-index lens materials is that the very people that need them most are also the most likely to experience one of their typical shortcomings. The more extreme the prescription, the more likely it is the wearer will be troubled by chromatic aberration in lower Abbe materials. For the most part, indices around the low 1.6’s are about the current limit on good Abbe performance. If you’re worried about chromatic dispersion, you can’t increase index greatly beyond where Optical Dynamics lenses are, so there’s not much thickness improvement to be gained. There can be significant cost differences though.

So if you have a moderate to low prescription where you don’t need the benefits of a high-index lens, high-index materials work very reliably. Hmmm, not the best story. It’s even less motivating when you think about the center and edge thicknesses required to produce a safe and sturdy lens for today’s rimless frames.

Don’t Just Take Our Word On It

When we say you should be using our lenses, there’s obviously a little bias involved. For a more impartial opinion, here’s what one of our customers has to say about them:

“Over the past couple years I have personally worn some of the “best” custom made progressive lenses available and the optics of the digital lenses from the Q-2100 are as good if not better. I am extremely impressed with the digital lenses the system produces and so are my patients.”

David Holliday, OD – Practicing since 1980 – Q-2100 user since 2000

Lens Troubleshooting

Question: I have a lens that is “speckled”, what can cause this and what can I do?

Possible Causes: Lens was removed from the annealing stages and cooled under running water while too hot. If a lens is cooled under running water while hot, it may have a “speckled” appearance caused by localized differences in the rates of cooling of the lens surface. These speckles can be numerous, irregularly shaped.

Solution: The lenses should be air cooled for several minutes before running water over them. If you have a “speckled” lens, returning it to the annealing oven for 5 to 10 minutes will usually eliminate the issue

Proper Sure Seal Application

ONE: Cut lenses to eye size of crib lenses down to remove tacky edges

TWO: To prepare your new Sure Seal tube for application, rotate the handle until you can just see the jelly like coating appear on the top

THREE: Rotate the handle 4 clicks and apply Sure Seal hydrophobic coating to the lens by blotting contents of tube once on front surface. Rotate the handle 4 more clicks and place a blot on the back surface. NOTE: Each application of Sure Seal will require 4 clicks of the handle.

FOUR: Carefully polish the jelly like coating over the entire surface of the lens with a Kimwipe or similar lens tissue until a uniform haze has developed over both the front and back surface. Be sure to recap the Sure Seal tube after use.

FIVE: Place Sure Seal coated lenses in Post Cure annealing oven for 10 minutes.

SIX: Upon completion of the 10 minute annealing cycle, wash the pair of lenses with Q-Soak and an AR cloth under hot running water to remove the excess buffed coating.

SEVEN: Clean lenses with Q-Spray

Note: if at any time you observe your hydrophobic coating to become discolored from its original condition, it should be properly disposed of. A new tube should be used at this point. Failure to do so will result in a less than quality product.

Lens Troubleshooting

Question: I have a lens that seems to have an aberration?

Possible Cause #1: Contaminants on the lens

Solution: Before annealing – If the lens is not properly cleaned before the annealing step, the contaminants may cause an optical defect. Carefully clean all lenses before annealing.

After annealing – A common error that can cause a defect is for an operator to lift up the lens from underneath with a fingertip when removing from the annealing stage of the Post Cure chamber. This can leave a permanent mark on the lens where touched, particularly if there was any lens monomer on the gloved fingertip. When removing the lens from the annealing stage, remember to handle the edges only.

Possible Cause #2: Pre-released lens

Solution:  Improper mold cleaning – Follow proper mold cleaning and preparation procedures.

Improper job queuing – If a job is run out of order, the initial curing step may cause the wrong amount of light to be directed toward the mold assembly, resulting in an increased possibility of a pre-release. Always follow the proper production sequence.

Wrong mold or gaskets selected – If the wrong mold or gaskets are used, the lens will be too thick or thin. Make sure to double check your mold and gasket selection as part of the production process.
