Hi Debbie,
I appreciate your insight and sharing of years of experience as a user of contact lenses as I, personally, haven't worn them in years because my dept would not allow contacts for many years because they weren't
aware of the updated information. However, I do think it can be useful to know if someone is wearing contacts in some cases because of a story of what happened to one of my colleagues when he was an undergrad a few years ago. He got PVA in his eye and it
caused the contact to be stuck to his eye. He did have to have it removed in the ER. That extra bit of information may be helpful in such a case. Not that I would try to remove someone's contacts before sending them to the eyewash. Honestly, I don't think
I could safely or easily remove someone else's contacts and I know the importance of time when an exposure occurs.
So, for all of us, I would just recommend that you still require the right kind of PPE, make sure that everyone knows contacts aren't PPE, and train people how to properly use an eyewash regardless of whether
or not someone is wearing contacts, and include in said training to not try to remove contacts by hand.
By the way, I don=E2=80™t have any issues with seeing students not wearing their goggles properly in the aforementioned colleague's labs

I have so far resisted weighing in on this thread (aren't you proud of me?) but it's time.
I've worn contact lenses since I was 13 years old, throughout a chemistry degree, work in industry, and over 20 years as a health and safety professional in academia. I have NEVER had an eye injury or exposure
that was in any way caused by contact lens wear. EVER. I'm meticulous about wearing safety glasses (or goggles, when necessary).
Contact lenses do not absorb chemicals from the air, do not hold chemicals against the eye, do not increase the risk of eye injury, should someone get a splash to the eye. Putting a dot on goggles or safety
glasses to denote a contact lens wearer - what does that accomplish? If someone gets a splash to the eye, they're going to activate the eyewash fountain and I'm here to tell you, if the eye is open, that contact lens will be washed out. Trust me on this
one.
It's counter-intuitive but prohibitions against contact lenses are not necessary, based on guidance from NIOSH, ACS, and the American Ophthalmic Association.
How are the hazards in lab different to a contact lens wearer than the hazards to anyone else in the lab? Why is a waiver necessary? And your undergraduates are wearing contact lenses in lab, whether you know
it or not.

Birkett's hypothesis: "Any chemical reaction
that proceeds smoothly under normal conditions,
can proceed violently in the presence of an idiot."
I would just say one thing, as this organization pushes for safety to be part of the training of future chemistry graduates, one should be careful by just following OSHA guidelines.
Even though OSHA may allow it, does not mean it is the prudent thing to do from the long term employee exposure they could have in the laboratory. If I dip my had in something once, is it a real issue, but if I do it day in and day out, what becomes the chronic
effects? I for one would never allow contacts to be worn in an undergraduate laboratory. I would also mandate chemical splash googles even if they need to be supplied as part of the lab fees. The students experience with safety is very limited and in most
cases they feel they are bullet proof. Even though the student may not feel they are in danger with what they are doing, it could be someone several feet away that causes the accident that can harm them. I understand students and educators may feel it is ok
at an undergraduate level due to the minimal hazards involved but if you want to build a long term safety mindset, at a minimum a waiver should be given to the student(s) to understand the hazards of contacts in the lab. I would worry that the lessons learned
in the undergraduate lab carries over to future lab work without understanding the hazards especially with so many chemicals not covered by OSHA. I do understand for every rule someone will have an exception.

Hello,
Our chemistry lab currently does not allow anyone to wear contact lenses in the labs. I'd like to propose that we allow contacts under safety glasses, goggles or face shields. We do use methylene chloride, many different corrosive chemicals
and potent compounds (mostly in chemical fume hoods but sometimes on the open bench top if dilute or in very small quantities). The dilemma I=E2=80™m facing is that OSHA states in 1910.1052 for Methylene Chloride that contact lenses
should not be worn when working with this chemical. I take this a recommendation not a hard rule. Some of my safety colleagues interpret "should not" to mean that contacts can be worn as long as I can prove that a
hazard does not exist (which I don't think I can do but I feel comfortable with the risk level, citing NIOSH recommendations and scientific studies but not all studies are well enough designed to prove there is no hazard).
My hazard evaluation would include listing the chemicals that are more of a hazard and training the chemists accordingly and letting the chemists decide if they want to take the risk or decide not to wear contacts and order the prescription
safety glasses that the company will buy. Some safety people want me to limit contact lens use only for chemical use that will pose no hazards. However, in a very large lab with hundreds of chemicals that are constantly changing this would be more work than
I feel value added and would confuse the chemists leading to non-compliance..
I would like your thoughts,
Mary
