Having a hard time picking a lens material? Lens material can be a difficult choice when purchasing glasses online, especially if you’ve never done it before. Glass vs plastic lenses, high index vs standard, polycarbonate? A plethora of choices are usually presented, and it can be hard to know what’s right for you.

The two major differences between glass and plastic are weight and scratch resistance. Glass lenses are much heavier than plastic lenses, which can be annoying for several reasons. The added weight on your nose can cause uncomfortable and unattractive pressure points as you wear the glasses all day, and it can also cause the glasses to slide down your face.

The other major difference is scratch resistance. Plastic lenses, while lighter, don’t have the scratch resistance of glass. Scratching glass lenses is a fairly difficult and unlikely thing to do unless you drop them, whereas plastic lenses are fairly easy to scratch, requiring a bit more care in handling.

Glass Vs Plastic Lenses: Essential Differences You Need to Know

If you’re trying to decide between plastic vs glass lens materials and don’t know all the differences, here’s what you need to know:

Plastic
  • Plastic is much lighter than glass, making it more comfortable to wear all day and limiting the glasses’ tendency to slide down your nose.
  • Plastic lenses are less reflective than glass lenses, making them clearer and less prone to glare.
  • Plastic lenses come in more colors and larger sizes than glass lenses, making them much more versatile. Whereas the frames you can get in glass are limited, you can get virtually any type of frame in prescription with plastic lenses.
Glass
  • Glass is much more scratch resistant than plastic, making the glasses last longer.
  • Glass lenses are also more brittle than plastic lenses. It is extremely unlikely that you will ever break or crack plastic lenses, but glass lenses are likely to crack, splinter, or shatter if dropped on a hard surface such as concrete or metal.
  • Glass lenses generally have a higher index than plastic lenses, making them slightly thinner and more attractive looking.

Since the creation of the plastic lens, glass lenses are much rarer than plastic when it comes to prescription glasses. The huge reduction in weight and versatility in prescription frames has caused plastic to win out in popularity in the glass vs plastic lens material race.
