Don't Give Up Your Eyesight
While we often take our eyesight for granted, in reality it is one of our most precious assets. (Try this experiment today: cover one eye with a gauze and a tape and attempt to work as you would normally for 30 or 40 minutes. It is a guaranteed ‘eye opener’). Yet many farm managers do not encourage or mandate the use of eye protection as a part of daily employment practices.
There are several reasons for this no doubt, some reasonable some selfish. Perhaps the time has come to think about adding eye protection as part of your own work wear and then encourage others on the farm to follow. It is a relatively simple and inexpensive precaution compared with the potential for loss. But the question remains, what types of eye protection are appropriate for agricultural work? Eye protection devices come in different forms such as goggles, face shields, and safety glasses. Each is unique and meets different requirements.
Prescription eyeglass wearers should be sure to either use safety glasses which incorporate prescription lenses or safety eyewear that fit over their own glasses, (See http://ohioline.osu.edu/atts/PDF-English/Eye-Protection.pdf). Though most modern prescription eyewear do have impact resistant lenses they are not constructed appropriately to meet the ANSI standards for impact as a unit and can fail if struck by debris.
Safety glasses provide forward impact protection, however they may not provide lateral protection. If lateral protection is required, side shields may be required. These can come as part of the safety glasses or they can be added. When adding or selecting glasses with side shields, be sure they do not interfere with peripheral vision. Safety glasses that are
Goggles are available in vented and unvented or splash variations. The unvented or splash variations are designed to be used to protect against liquids or chemical vapors (For more details, visit http://www.farmsafety.ca/factsheets/tailgate-e/eye-prot-tg.pdf). Be sure that the goggles you choose meet the needs of that particular work situation. Some pesticide or chemical use situations call for a full face respirator for complete protection.
It is recommended that the welding mask be fitted with a number “10” lens when welding at 200 amperes or less. Check your welder’s manual for more information on the lens requirements for the type of welding you are doing. (Also see, http://www.farmsafety.ca/factsheets/tailgate-e/eye-prot-tg.pdf).
Finally, ultraviolet radiation has not only been shown as a causative factor in skin cancer it also has been shown to cause damage to the eye. To help prevent such damage sunglasses or appropriately tinted safety glasses should be worn when working outdoors. The current US standard for sun glasses is ANSI Z80.3-2001, which includes three transmittance categories. According to the ANSI Z80.3-2001 standard, the lens should have a UVB (280 to 315 nm) transmittance of no more than 1% and a UVA (315 to 380 nm) transmittance of no more than 0.3 times the visual light transmittance (http://en.wikipedia.org/wiki/Sunglasses). When purchasing sun glasses or tinted safety glasses be sure they are marked as meeting the ANZI standard Z80.
