What do you use for lens wipes??

[Chris Ryser]

What scientific discussion on this thread .................................. all about what make of wipe you are using, and nobody even describes the proper way of doing it.

Anybodies eyeglass frame is full of bacteria, some of them can be dangerous to anybody else by just touching them and then not washing their hands properly and immediately after.

These days you can go for a pedicure, and the girl doing it is putting on surgical gloves before touching you. So why not use the the same idea on glasses which are the closest to the part of the body that has the most body secrections anywhere. The nose, the eyes, mouth and the ears. All these secretions are a centrum of bacteria that are looking for a new environment to multiply in.

Eyeglasses coming into an optical store to be worked on should and have to first go into good class Ultrasonic cleaner that also heats the solution, filled with a top quality cleaner and not with the cheapest dishwasher soap, to not only knock off the visible dirt, but also get rid of the beacteria present. Todays Ultrasonic cleaners are made with latest technology surfactants.

When glasses are real dirty the removal of the lenses is also recommended as the lens bevel and frame grooves contain a fair amount of even visible dirt.

From the Ultrasund treatment go under a good warm water rinse, dry the glasses with a clean non greasy towel, and you are ready to work on the frame to do whatever has to be done.

Ther is definitely no need for use of any brand of towelette in any specialized opticians store. but some improvement in good service and you might even charge for it.

You can use microfiber cloth or Zeiss lens wipes.

Because the question was about what wipes people prefer, not how to use them. It's a rare case of an on topic thread where someone asks a simple question and gets a lot of good answers.

I use Nanofilm's "clarity clean it" and Kim wipes here in the office. I don't like to use a cleaning cloth between patients, I worry about germs. It usually takes me 2 Kim wipes to dry the lenses properly. I've noticed, like the OP, that others pull out 4 or more before even trying to clean them off with 1 or 2 wipes...I guess because the Kim wipes are so thin, they feel like they need to grab a bunch to make them absorbent...but, all I hear is "cha-ching" when they do that!


I use a large cleaning cloth on the demo lenses throughout the dispensary, and alcohol on a tissue for the nosepads. I give the patient their own small spray bottle of that "clarity clean it" and a cleaning cloth @ dispensing.

Perhaps Chris might offer up the long term side effects of daily skin exposure to isopropyl alcohol, denatured alcohols, and methanols.

Opticians buy, sell and use lens cleaners. The market is full of lens cleaner suppliers that cut each others throat to make a sale to an optical retailer. More than 90% of all lens cleaners are made with "Isopropyl Alcohol" CASRN number 63-67-0. Some of them are also recommended for use with AR coated lenses while the alcohol is actually not too healthy for the AR coating.

It is also not too healthy for human skin contact and its fast absorbtion into the body. I found an excellent description on it, please read it and think about it next time you are looking to buy or sell lens cleaner.

ISOPROPANOL CASRN: 67-63-0

Human Health Effects:

Toxicity Summary:
IDENTIFICATION: Isopropyl alcohol is an aliphatic alcohol hydrocarbon. It is prepared from propylene, which is obtained in the cracking of petroleum or by the reduction of acetone. It is a colorless liquid which is soluble in water, alcohol, ether, acetone, benzene and chloroform. It is insoluble in salt solutions. It has a slight odor resembling a mixture of ethanol and acetone and has a slight bitter taste. It is used in antifreeze, industrial solvent, solvent for gums, shellac, essential oils, in quick drying oils, creosote and resins; extraction of alkaloids; in quick drying inks; in denaturing ethyl alcohol; in body rubs, hand lotions, after shave lotions, cosmetics and pharmaceuticals; in manufacture of acetone, glycerol, isopropyl acetate; antiseptic; rubefacient ; and pharmaceutical aid. HUMAN EXPOSURE: Toxic effects include central nervous depression, liver, kidney, cardiovascular depression and brain damage. It can cause drowsiness, ataxia, stupor, coma and respiratory depression, irritation of mucous membranes and eyes, gastritis, gastric hemorrhage, vomiting, pancreatitis, cold clammy skin, hypothermia, miosis, tachycardia, slow and noisy respiration. High risk of circumstances of poisoning: Accidental ingestion of rubbing alcohols/toiletries by children. There is a potential exposure from dermal and inhalation exposure in children during isopropyl alcohol sponging for control of fever. Intentional ingestion for alcoholic effect or in suicide attempts. Occupational or accidental exposure to liquid or its vapor in industrial applications. Individuals exposed to isopropyl alcohol include the following: workers in the pharmaceutical industry, cosmetic industry, chemical industry, petroleum workers, laboratory workers, printers, painters and carpenters and cabinet makers. There is little absorption through intact skin. Isopropyl alcohol is a potent eye and skin irritant. 80% of an oral dose is absorbed within 30 minutes. Absorption is complete within 2 hours although this may be delayed in a large overdose. Alveolar concentration is correlated to the environmental concentration at any given time. Isopropyl alcohol is absorbed through intact skin on prolonged exposure. Isopropyl alcohol distributes in body water with an apparent volume of distribution of 0.6-0.7 L/kg. 20-50% of an absorbed dose is excreted unchanged. Most isopropyl alcohol is oxidized in the liver by alcohol dehydrogenase to acetone, formate and finally carbon dioxide. Acetone is slowly eliminated by the lung (40%) or kidney. Clinically insignificant excretion occurs into the stomach and saliva. Related keto acids are not produced in sufficient quantities to cause a severe metabolic acidosis. Inebriation, peripheral vasodilation has occurred. In children, hypoglycemia is particularly severe when poisoning following fasting, exercise or chronic malnutrition Lactic acidosis may occur in patients with severe liver disease, pancreatitis or receiving biguanide therapy or as a result of the hypovolemia which frequently accompanies severe intoxication. ANIMAL STUDIES: Isopropyl alcohol most closely follows first order kinetics, with a half life of 2.5 to 3.2 hours. The elimination half life of the active metabolite acetone is significantly prolonged to about 5 hours in rats. In rat hepatocytes the following has been observed: marked depletion of glutathione, increased malondialdehyde production, decreased protein sulfhydryls content and leakage of lactic dehydrogenase with loss of membrane activity.

Evidence for Carcinogenicity:
Evaluation: There is inadequate evidence for the carcinogenicity of isopropanol in humans. There is inadequate evidence for the carcinogenicity of isopropanol in experimental animals. Overall evaluation: Isopropanol is not classifiable as to its carcinogenicity to humans (Group 3).

I use the Zeiss lens cleaning wet wipes too.They work well but you have to make sure it's not too wet before you apply the wipes as otherwise it will leave streaks on your lens.
