Reading glasses are eyeglasses that are designed to help people who have difficulty reading or doing close-up work due to presbyopia, a common condition that affects the eye's ability to focus on nearby objects. Reading glasses can be purchased over-the-counter without a prescription and are available in a range of magnification strengths.

As for glasses that are designed specifically for women, there are many different styles and options available. Women's reading glasses can come in a variety of shapes, sizes, and colors to suit individual preferences and face shapes. Some common styles of women's reading glasses include cat-eye, round, rectangular, and oval frames.

It's also possible that by "injection" you may be referring to the material used to make the frames. Injection molding is a manufacturing process that involves injecting a molten material, such as plastic or acetate, into a mold to create the glasses frame. Injection-molded frames are often lightweight, durable, and comfortable to wear. Many reading glasses are made using this process, including those designed for women.
