Whether the lines are solid or dashed, using circles for key milestones creates visual contrast and interest, and makes the values easier to recognize and compare across the board. Colors should be ...

Patients were tested for binocular acuity on Sloan Low-Contrast Visual Acuity charts at contrasts of 1.25%, 2.5%, and 100% (high contrast).

Researchers have found in a phase 3 trial that phentolamine ophthalmic solution 0.75% led to significant improvements in ...

Furthermore, visual function measures of best-corrected visual acuity, contrast sensitivity, and microperimetry are all closely associated with activities of daily living in patients with AMD.

The LYNX-2 study met its primary endpoint of a gain of three lines (or 15 letters) or more of distance vision improvement on a low contrast chart in low light conditions after 15 days of dosing.
