Heavier than plastic. The weight of glass lenses can get uncomfortable, especially if you plan to wear them all day. Their heaviness can also cause them to frequently slide down your face, which can become irritating over time.

Keep in mind though, that while this factor may have been a cause for concern in the past, nowadays, the option to add an anti-scratch coating to your lenses eliminates the worry that your lenses will get scratched easily.

Wide variety of transition lens options. If you are interested in purchasing transition (photochromic) lenses, plastic lenses are a great choice for you. Most plastic lenses are able to accommodate a large variety of transition lens options.

Delicate. Glass frames, though scratch resistant, are more delicate than plastic frames and can easily crack or even shatter upon impact. This is an important deciding factor if you lead an active lifestyle, have young children at home that may try to pull your glasses off your face, or if you are choosing a lens material for a child’s eyeglasses.

Large variety. Plastic lenses are compatible with a large variety of frames that come in all different shapes, sizes, thickness and colors. This means you will have a much larger selection of frames to choose from when choosing plastic lenses over glass lenses.

Lightweight. Plastic lenses are by nature much lighter and more comfortable than glass lenses. This is an important consideration if you plan to wear your glasses all day. Their light weight also helps them to stay in place longer, with less of a chance that they will slip down your nose multiple times per day.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

When deciding between glass and plastic, think about what you are looking for in a lens and which type of lens will suit your lifestyle best. If you have any questions or concerns, ask your optometrist or optician for advice.

Thin and attractive. Glass lenses are typically manufactured with a higher index, which gives them a thinner, more attractive appearance.

Thankfully, nowadays, with the advancement of technology, not only do we have temples on our frames to keep our glasses in place and a wide variety of optical lenses and frame styles, but the lenses themselves are also being manufactured with plastic materials to make up for qualities glass lenses cannot provide.
