Answer:
Not everyone who needs glasses wants to wear contacts, but nine out of 10 people who want to wear them can wear contacts. However, contact lenses may not be a good option for people who: Have had repeated eye infections. Suffer from severe allergic reactions.
It is strongly recommended that students do NOT wear contacts lenses in the laboratory. Chemical vapors may penetrate the contact lens material and cause the lens to adhere to one's eye, which could be detrimental to the eye. Goggles are not vapor tight and do not completely eliminate this absorption.
The general advice is to avoid wearing contacts for more than eight hours a day. However Aimee, like many people, had been wearing them for much longer - in her case, for more than 14 hours every day.
Safety goggles for eye protection must be worn properly in the laboratory at all times. If you need to remove your goggles, step outside the laboratory to do so. Prescription eyeglasses (even with safety lenses) do not provide adequate eye protection, especially from the sides.
