A little visual challenge to finish the week! There are TWO shapes hidden in this image. Can you identify both?

Color vision is more complex than simply distinguishing red from green. Different types of color vision deficiency can affect how people perceive and distinguish certain colors.

For today's Friday challenge, we're keeping things lighthearted.
What shapes do you see? Share your answer in the comments, and challenge a colleague!

Can the eye chart you use change a patient's visual acuity result? 👁️

Research involving 163 eyes found that ETDRS testing produced scores averaging 6.5 letters better than conventional Snellen testing. For patients with poorer vision, the difference was even greater.

Snellen charts have been used since 1862, but standardized logMAR charts offer important advantages in chart design, scoring precision and measurement consistency.

Explore the clinical evidence behind these differences and what they mean for everyday practice.

Is an 85-arcsecond stereoacuity result normal? 👁️

It depends on who you're testing.

Research using the Frisby Stereotest found that median stereoacuity measurements varied considerably between children, younger adults and older adults.

For eye care professionals, these findings reinforce why age and testing conditions matter when interpreting depth perception results.

The Frisby Stereotest provides a glasses-free, real-depth approach to binocular vision assessment.

Explore the published research, normative data and practical clinical considerations.

Not all preschool eye charts are designed the same way.

Updated vision screening recommendations emphasize age-appropriate symbols, proper chart design and consistent screening procedures.

Whether you're using LEA SYMBOLS® or HOTV, details such as crowding bars, testing distance and follow-up protocols can make a difference in how effectively children are screened.

Our article explores what school nurses and pediatric screening programs should consider when reviewing their equipment. Does your screening program currently use LEA SYMBOLS® or HOTV?

Does the brightness of an eye chart affect visual acuity testing?

Consistent chart illumination is an important part of reliable BCVA and LCVA assessments. For eye care professionals, understanding the differences between illuminated and calibrated equipment can help when choosing the right testing setup.

Explore the role of luminance, ETDRS charts, and Good-Lite's illuminated cabinet options.
