Final answer:
False, Personal glasses are not true substitutes for goggles because they do not offer the same full coverage and protection from all angles that goggles are designed for, especially against UV radiation and other hazards. While they do provide some UV protection, their main purpose is vision correction, unlike goggles which are designed for eye safety.
Step-by-step explanation:
The statement that personal glasses are substitutes for goggles is generally false. While personal glasses can provide some protection and most plastic lenses offer more UV protection than glass lenses, they are not a complete substitute for goggles. Goggles are designed to offer full coverage that protects the eyes from all angles, including potential exposure to ultraviolet radiation and other hazards that personal glasses may not be designed to shield against.
Personal glasses and contact lenses mainly serve the purpose of correcting vision problems such as myopia or astigmatism. Contact lenses, in particular, offer advantages such as staying at a fixed distance from the eye and conforming to its movement, thereby providing superior peripheral vision. Personal glasses, though they can help with vision correction, do not move with the eyes and thus do not offer the same level of peripheral vision or consistent distance from the eye.
When it comes to protective eyewear in environments with potential eye hazards, personal glasses should not be relied upon as a substitute for properly designed safety goggles that offer complete protection.
