Glasses, also known as eyeglasses or spectacles, are worn on the face to correct vision problems or to protect the eyes from harmful UV light. There are several types of glasses that serve different purposes, including:
- Prescription glasses: These glasses are worn to correct vision problems such as nearsightedness, farsightedness, and astigmatism. They are prescribed by an eye doctor based on the results of an eye exam.
- Non-prescription glasses: These glasses are worn for fashion or to protect the eyes from harmful UV light, but do not have a prescription to correct vision problems.
- Reading glasses: These glasses are worn to help people see small print more clearly. They are often used by people who have difficulty seeing small print due to age-related vision problems, such as presbyopia.
- Sunglasses: These glasses are worn to protect the eyes from harmful UV light and to reduce glare. They are often worn outdoors or when engaging in activities that involve bright light, such as driving or skiing.
- Safety glasses: These glasses are worn to protect the eyes from hazards in the workplace or during activities such as woodworking or construction. They may have special features such as impact resistance or side shields to provide additional protection
