Contact Lens Flashcards
False CL reports
Electricity caused CL to be weld to the eye. Cannot be replicated. Very unlikely.
Student wearing soft CL was working with ethyl acetate and then dx with Optic neuritis because the solvent was absorbed into the CL. Likely caused by inhalation of the solvent.
Benefits of wearing CL in the work environment
Enhance visual acuity and VF Decreased reflections Better performance in rain and mist Less problems with perspiration Less likely to smear/smudge no fogging Better seal with mask/goggles
Potential hazards of CL in the work environment
Chemical, mechanical, physical.
Chemical hazards with CLs
Hard CL
-Chemical unlikely to become trapped behind lens
Soft CL
-Water soluble gases and fumes can be absorbed. Might prolong exposure but at a low concentration. Just be cautious.
OSHA has some regulations against specific chemicals.
Mechanical hazards with CLs
Hard
-Chance of foreign body becoming trapped behind lens is possible. Lens could shatter with enough energy.
Soft- May provide slightly more protection from foreign bodies striking eye.
Physical hazards with Cls
Temperature extremes, IR, UV, and microwave. No negative effect with this for soft or hard.
OHSA regulations about CL in the workpalce
CL do not pose hazards to the weber and has determined that additional regulations is unnecessary.
Use of RGP and soft CL in all workplaces with all types of respirators is acceptable. Allows tight seal on respirator.
NIOSH’s thoughts on CL in the workplace
National institution for occupational safety and health
Concluded that you should not wear contact lenses while working with hazardous materials
ACOME thoughts on CL in the workplace
American college of occupational and environmental medicine
They should be allowed to wear CL as long as safety guidelines are followed.
