Does the program account for the asphericity and total add of the lens to calculate final thickness perameters? When the lens is too thin, where on the shape is it too thin? Could be a combination of...

Perhaps someone out there knows where on might obtain advanced certification
credits. I rarely see them offered and most online sources don't seem to list them either. Any information on these...

It sounds like your patients have adapted to the magnification inherent in their previous lenses so successfully that altering that magnification causes them to lose their perception and spatial...

I doubt there is a conspiracy here, but it might be worth calling Visionease to find out what the problem is. You might be surprised to find that they are having no problems with inventory.

Do NOT use any Ar stripper on glass lenses, the acid in it will etch
and fog glass lenses. Also, take care to use splash precautions, rubber gloves or tongs to prevent exposure to skin. The acid in...

I believe that super hard coatings do perform better than the standard scratch coatings but I don't know of one that is tintable
at this time. Whenever a customer asks me if they can be scratched, I...

Homer is right about the patternless edgers, they will go far to reduce all sorts of edger related problems. One thing I have noticed is that poly lenses tend to show stress more than resin lenses...

I find that it will depend on the patient expectation. In many cases, we as opticians can assist in forming that expectation to meet a favorable outcome.

If the patient is a previous wearer, ask...

You are probably the owner of some very old lens inventory. Most quality lens manufacterers have been adding uv inhibitors in their stock lenses for many years that prevent this yellowing. Even so,...

Quality, selection, support, rep knowledge, product suitability for market are just a few things a frame line should provide to make your long term investment worthwhile. When you find this...

The steaking you describe is usually caused by the lenses being
greatly sensitive to the dye run off. You can reduce this by dropping the tint bath temperature. If the gradient desired has a...

I compared the cost of ashperic poly with the Trilogy product and
found it to be comparable. When I have a prescription that would
benefit from this combination of properties, I will opt for...

Richard Homier introduced this board to me and others at a state
meeting. I have not been able to visit here recently due to work load but I do enjoy reading about our common concerns, suggestions,...

Transitions can be obtained on many different lens indecies. Aside from transitions, I have noticed that some mid index lens matrials demonstrate a more supple character that might lead to some...

Bev, I am a great fan of the Gerber Kappa edger. You may have seen references to thin lenses breaking on Briot edgers. Well the Gerber product allows you to run a simple program that gives thin...

Seen only a few frames recently from either country. They are clearly produced to fall in the budget or high profit catagory. If one could avoid the costs of shipping this product as a result of...

UTMC is Sola's proprietary ar coating. You can tell if it is this coating by observing how water flows off the lens. Because UTMC does not have a hydrophobic finish coat with it, water will tend to...

These topics constantly remind me to self evaluate and resolve to be better for the next customer. It is a habit that has paid off over the years. The question that has driven that concept is:

I read in a trade article that allowing the lenses to soak in a warm
solution of soapy water will allow the blocks to come off the lens gently. I wonder if by this process, the hydrophobic coating...

I like your idea of biking for the fun of it. The fund raiser concept is gravy. Now I can fulfill the image some have of me as an optical
peddler.

Dave, I tried the microwave trick and at 6300ft above sea level, it is more like painting the inside of your microwave with hot dye. A
