Ask an Optician

What does an optician do?

An optician fits eyeglasses and contact lenses. They analyze and interpret prescriptions written by ophthalmologists or optometrists to determine which eyeglasses are best suited to the patient's lifestyle and visual needs. They take eye measurements to insure proper lens placement in the eyeglasses' frame and verify the accuracy of the finished product. They may manufacture (grind) lenses from raw materials and cut them to fit into the frame.

Why are safety eyewear fittings important?

Proper fit ensures maximum eye protection. Safety glasses should rest firmly on top of the nose and close to, but not against, the face. If the glass slides down even a small amount, the user will lose some protection. Your safety glasses have a three-point fit, meaning the frame should touch the face in three places - at the nose bridge and behind each ear. Temples should wrap around the head, with slight pressure behind the ear, not above the ear.

Why are my safety glasses fogging up?

Typically, your safety glasses fog up when they are exposed to an extreme variation in temperature or humidity - like when someone drives a forklift from inside a warm factory out on the loading dock in the winter. But it can also happen when you're working hard physically and your body temperature rises compared to the air around you. This can be avoided by treating your safety eyewear with an anti-fog coating.

Will safety eyewear weaken or ruin my eyesight?

No. If you do not wear prescription glasses, safety eyewear is no different than wearing non-prescription sunglasses. And if you do wear glasses, safety eyewear can be made to your prescription.

Can contact lenses be worn at work?

Contacts can be worn in conjunction with non-prescription safety eyewear.

How should I maintain my protective eyewear?

  • Clean your safety glasses daily. Follow the manufacturer's instructions. Avoid rough handling that can scratch lenses.
  • Store your safety glasses in a clean, dry place where they cannot fall or be stepped on. Keep them in a case when they are not being worn.
  • Replace scratched, pitted, broken, bent or ill-fitting glasses. Damaged glasses interfere with vision and do not provide protection.
  • Replace damaged parts only with identical parts from the original manufacturer to ensure the same safety rating.

Can my protective eyewear be sterilized?

Yes. An ultraviolet light sterilizer is the simplest way to sterilize them.

I have a smaller head; can I still wear any style of frame? Or should I avoid certain ones?

There are hundreds of prescription safety frames available. It is important that you have a good fit and a safety frame that can carry your particular prescription. The type of work and environment can also dictate which frame style would be your best choice.

My nose has a small bridge. Can you help me find the right safety eyewear for me?

Yes, it is very important that the frame fits properly on your bridge. With adjustable nose pads and proper adjustments, most frames can accommodate a person with a small bridge.

Can photochromic lenses be worn in an industrial environment?

Yes, sunsensor or photochromatic can be worn in the industrial environment. Lenses can now be made in polycarbonate or industrial strength material for use in an industrial setting. You need to keep in mind that sunsensor or photochromatic lenses are activated by UV or the sun. The lenses will not change inside without natural light.
