How To Choose From The Lens Options:

Here I will explain in simple terminology the various lenses that you could opt to have. This will help you choose and decide which lens is best for you!

Optical lenses are available in Glass and plastic materials.

Plastic lenses are by far the most common lens type. I rarely prescribe glass lenses in my practice. However, if someone is an existing glass lens type wearer and prefers glass to plastic then it is recommended to stick with glass lens.

Below, I have outlined some of the characteristics that I have encountered with glass and plastic lenses:

GLASS: ADV:

• Harder lens surface protects the lens from minor scratches. (However, hard coating on a plastic lens counteracts this)

• Glass lenses are the better option for very high prescriptions.

DISADV:

• Brittle compared to plastic.

• Heavy compared to plastic.

Optically there is no real difference between modern day plastic lenses and glass.

A lot of manufacturers don’t manufacture glass lenses at all as they are not as popular as plastic. A bit like VHS and DVD!

Therefore, in my opinion for most people plastic lenses are better than glass
