For many people, a new pair of glasses solves problems like blurred vision or eye strain. But for some patients, standard spectacle lenses don’t completely relieve visual discomfort.

If the images seen by each eye are slightly different in size, the brain can struggle to combine them into one clear picture. This condition is known as aniseikonia and can cause a range of frustrating symptoms.

At Melton Optical, we offer advanced lens technologies such as Shaw Lenses that are specifically designed to address this issue and improve visual comfort.

Why Image Size Differences Matter

Your eyes work together as a team. Each eye sends an image to the brain, and the brain combines them into a single three-dimensional picture.

However, if the images from the two eyes differ in size, shape, or clarity, the brain may struggle to fuse them properly.

This can lead to symptoms such as:

These symptoms are more common when there is a significant difference in prescription between the two eyes.

What Are Shaw Lenses?

Shaw Lenses are specially designed spectacle lenses that help correct differences in image size between the two eyes.

Unlike standard lenses, Shaw lenses are carefully customised to adjust the magnification seen by each eye. This allows the brain to combine the images more easily and comfortably.

For many patients, this can lead to:

Because the lenses are tailored to the individual prescription, they can be particularly helpful for patients who have struggled to adapt to traditional glasses.

Shaw Lenses and Lazy Eye (Amblyopia)

Shaw lenses may also play a role in improving vision in some patients with lazy eye (amblyopia).

Traditional treatment for amblyopia often involves patching the stronger eye to encourage the weaker eye to work harder. However, patching can be difficult for some children.

By correcting image size differences, Shaw lenses may help the brain use both eyes together more effectively. In some cases, this may support improvements in visual function without relying solely on patching.

An optometrist can determine whether this approach is appropriate based on the individual case.

Who Might Benefit From Shaw Lenses?

Shaw lenses may be considered for patients who:

A comprehensive eye examination is needed to determine whether these lenses may be helpful.
