VISUAL ACUITY

This study tested ACUVUE Abiliti contact lenses in 75 children to see if they can slow the progression of nearsightedness (myopia). The lenses were worn daily for up to 2 years. Researchers measured changes in eye length and vision every 6 months. The goal was to control the dise…

This study checked if a new digital vision test you can do at home is as accurate as the standard eye charts used in clinics. 70 adults who wear glasses took both tests, and researchers compared the results. The goal was to see if the DIY test could reliably measure distance and …

This study tested a special lens (AcrySof IQ Vivity) implanted during cataract surgery to see how well it restores vision at different distances. Thirty adults with cataracts received the lens in both eyes. Researchers measured their eyesight and satisfaction 1 and 3 months after…

This study tested two different daily disposable multifocal contact lenses in 74 adults aged 40 to 70 with presbyopia (age-related blurry near vision). Participants wore each lens type for about a week, and researchers measured how well they could see at distance, arm's length, a…

This study tested special daily disposable contact lenses designed for people who need help seeing both near and far, including those with astigmatism. 176 adults aged 40 to 70 wore the lenses and had their vision checked at a clinic. The main goal was to see how well the lenses …

This study tested how well people see while wearing two different cosmetic contact lenses. Fifty-three adults who already wear soft contacts took part in a single visit. Each person tried both lens types, and their distance vision was measured using an eye chart. The goal was to …

This study tested approved contact lenses to see how well they improve vision and fit the eye. 85 people who already wear soft contact lenses took part. The main goals were to check if the lenses give 20/20 vision and fit comfortably after one week of wear.

This study tested three different daily disposable silicone hydrogel contact lenses to see how well they fit and performed. Twenty-two adults aged 18 to 40 who use digital devices at least 4 hours a day took part. Each person tried all three lens types, and researchers checked le…

This study tested whether training with action video games or stroboscopic glasses can improve dynamic visual acuity—the ability to see moving objects clearly. Thirty athletes without vision problems participated. The goal was to find which method better boosts visual performance…

This study looked at how much toric (astigmatism-correcting) soft contact lenses rotate in people who already wear them regularly. Six adults aged 18 to 39 wore two different lens types in a crossover design, and their vision sharpness was measured. The goal was to understand len…
