Visual performance comparison between contact lens‐based pinhole and simultaneous vision contact lenses

Visual performance with simultaneous vision multifocal contact lenses.

PURPOSE   The aim was to assess visual performance after PureVision high addition multifocal contact lens (PM) fitting through contrast sensitivity measured under different illumination levels for both distance and near. METHODS   In a cross-over study, 20 presbyopic patients were randomly assigned to PM or spectacles. Near contrast sensitivity was measured with the Vistech VCTS 6500 system. ...

Predicting and assessing visual performance with multizone bifocal contact lenses.

PURPOSE To investigate how bifocal contact lenses, when combined with the aberrations of the eye, will affect visual performance. Also, to investigate the relationship between the patient's predicted and actual visual benefit with bifocal contact lenses. METHODS The monochromatic aberrations of 16 subjects were measured and used to simulate visual quality with three bifocal contact lens desig...

Visual Simulation of Retinal Images with Various Designs of Pinhole Contact Lenses

Presbyopia, which manifests from loss of accommodative function of the crystalline lens, is a ubiquitous visual disability of the aging eye. The demand for clear, comfortable near vision is increasing with the widespread use of devices such as mobile phones, tablets and computers. It was recently reported that presbyopia is related to difficulties with activities of daily living and resulting s...

Athletics impulsively traits: A comparison between contact and noncontact sports

The aim ofthisstudy was to investigatedifferentaspects ofimpulsivityin the athletes of contact and non-contactsports. volunteer participants were 60 athletes of contact (age: 25.9±4.6 years) and non-contact (age: 27.6±4.9 years) sports. Participants were asked to complete the Barratt’s Impulsivity Scale (BIS-11) and participate in continuous performance test(CPT). Multivariate analysis of varia...
