Visual acuity and reading performance with presbyopia-correcting intraocular lensesPerisMartinez, C
What is visual acuity? Visual acuity refers to the clarity or clearness of the vision, a measure of how well a person sees.
Factors influencing self-reported vision-related activity limitation in the visually impaired. Participants also completed clinical tests of visual function (distance visual acuity and near reading performance both with and without low vision aids [LVAs...

When you've completed a visual acuity test, you'll get results as a fraction. The top number refers to the distance you stand from the chart. In most cases, this will be 20 feet. The bottom number refers to the distance at which an average person with normal eyesight could read the s...
reading material is less by a factor of 2.5× the acuity needed. Consistent with previous study9, theactualnear VA demand was thereafter obtained by subtracting 0.398LogMAR (given that a 2 × acuity reserve is equivalent to 0.3 log units or 3 LogMAR lines, and a 3 × acuity ...
22 visual skills that impact our daily lives. Seeing clearly (acuity), "20/20", is just one of these skills. Most standard vision screenings do not test all of thesevisual skills; therefore, problems in these areas go undetected and can take an unnecessary toll on children in the ...
In an apposition eye, it is the inter-ommatidial angle (Δφ) that determines how the overall image is sampled. Its acuity is inversely proportional to Δφ but the overall performance of the eye also largely depends on the optical quality of the ommatidia, the rhabdom dimensions and the ...
One main problem for children with deficits due to periventricular leukomalacia is decreased visual acuity with crowding, that is, an inability to identify symbols in a line, while single symbols of the same size may be identified. A question addressed in the study is what kind of strategies ...
Visual acuity with the near card is often recorded using the Snellen fraction or the standard Jaeger notation (J1, J3, etc.). When near visual acuity is tested, presbyopic patients older than 40 years of age should wear their reading glasses or bifocals. Near acuities are not as accurate as...
