Your eye care doctor may have asked you a few times if you want single-vision lenses or multifocal lenses for your glasses. These terms are often confusing no matter how many times they’ve been explained.

Why are trifocal lenses costly? This is because this vision correction tool has three different vision ranges embedded into a single lens.

When should I get high index lenses?

Are polycarbonate lenses suitable for you?

How do photochromic lenses work? Decades ago, photochromic glass lenses only came in gray color and tended to darken quickly if one lens was thicker than another. The light-adaptive technology was short-lived, making the lenses appear darker indoors.

Transition lenses are special lenses that adapt to changing light conditions. This type of lens is made to allow users to see clearly regardless of the prevailing light conditions.

If you wear glasses to help you see better or just for fashion value, they will be times when your glass will fog up.

An updated version of bifocal and trifocal lenses, progressive lenses provide a seamless look, so sometimes they are called no-line bifocals.

Bifocal lenses are divided into two separate parts to accommodate a combination of any two different prescriptions into one lens.

The viewing regions of progressive lenses are usually just in the lower portion of the glasses. Single vision lenses, on the other hand, have their viewing power distributed across the lens.
