What Is Foveal Shape Discrimination?

Posted by amess on Sep 9th 2021

When it comes to vision, there are many terms that we are not initially familiar with. However, if you or someone you know may have age-related eye health issues, you may have heard of foveal shape discrimination. Even if you have heard of this term, it’s difficult to fully understand what it means and why it matters for your vision. Here’s what you need to know.

Foveal Shape Discrimination: What Is It?

Foveal shape discrimination defines the eye’s ability to distinguish various shaped targets from one another. It’s the capability to determine the misalignment of an object relevant to other objects in the same space. It can be measured under various lighting conditions to account for different times of day. It can also be measured by showing shapes with various sharp and blurry lines on a monitor.

Why Does Foveal Shape Discrimination Matter?

Most visual function terms matter to everyone. However, this term is particularly important for those who have or are at risk for age-related eye health issues. When age-related eye health issues worsen, there is build up in your eye that can distort your vision, causing straight lines to look wavy. This visual distortion causes daily tasks to become difficult such as cutting food, writing, and driving. When your foveal shape discrimination is bad enough, it can even threaten your independence.

Amsler Grid

An Amsler grid is an at-home test to ensure your vision isn’t becoming distorted. Eye doctors often give these to patients who are identified with age-related eye health issues so they can track their vision. If there is any decline, this grid can help them recognize it quickly.

How Can I Improve Foveal Shape Discrimination?

As mentioned, foveal shape discrimination is affected by the buildup that occurs in the eyes due to age-related eye health issues. As of now, there is no cure for these issues. However, nutrition has been shown to have a positive impact on eye health and visual function. Specifically, an antioxidant called zeaxanthin has been demonstrated to improve foveal shape discrimination, but only when ingested in high amounts (8+ mg).


Zeaxanthin is found in brightly colored fruits and vegetables, but you’d need to eat 20 ears of corn a day to get the amount of zeaxanthin your eyes need to stay healthy. That’s why many eye doctors recommend supplementation. EyePromise is the #1 eye doctor recommended eye vitamin brand and includes a line of clinically proven formulas for age-related eye health issues.
