VISUAL ACUITY

This study tested ACUVUE Abiliti 1-Day soft contact lenses designed to manage nearsightedness (myopia) in children. Over 1 to 2 years, researchers measured changes in eye length and vision in 75 participants. The goal was to see if these daily-use lenses can safely slow the worse…

This study checked if a new digital visual acuity test can accurately measure how well people see, compared to standard eye charts. 70 adults who wear glasses took the digital test and standard tests. The goal was to see if the DIY test gives similar results for both distance and…

This completed pilot study tested two different daily disposable multifocal contact lenses in 74 adults aged 40 to 70 with presbyopia. Participants wore each lens type for about a week, and researchers measured how well they could see at distance, intermediate, and near distances…

This study compared two types of cosmetic contact lenses to see if they affect vision. 53 soft contact lens wearers tried both lenses and had their eyesight measured. The results showed that both lenses provided clear vision, similar to standard contact lenses.

This study tested a special lens implanted during cataract surgery to see if it improves vision at far, middle, and close distances. Thirty adults with cataracts received the lens in both eyes. Researchers measured their vision and satisfaction 1 and 3 months after surgery.

This study tested a new daily disposable contact lens designed for people with astigmatism (blurry vision from an irregularly shaped cornea) and presbyopia (age-related difficulty seeing up close). 176 adults aged 40-70 wore the lens for one week. Researchers measured how well th…

This completed study looked at how different amounts of light scatter affect vision when wearing contact lenses. Thirty-one adults aged 18 to 69 who already wear soft contact lenses tested two types of ACUVUE lenses. The goal was to measure visual clarity under high-contrast ligh…

This study tested how well three different daily disposable silicone hydrogel contact lenses fit the eyes of 22 adults aged 18 to 40. Each person tried all three lens types in a random order. The main goal was to see if the lenses stayed in place and moved properly on the eye.

This study tested two already-approved contact lenses to see how well they help people see clearly. 85 adults who normally wear soft contact lenses wore each lens for about a week. The main goals were to check if each lens gave 20/20 vision or better and if the lenses fit well. S…

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 healthy adults without vision problems took part in short training sessions. The goal was to compare which method…

This study looked at how much soft toric contact lenses rotate in the eyes of people who already wear them. Six participants had their vision checked after wearing different lenses. The goal was to understand lens rotation and its effect on eyesight.
