Assessing Dynamic Reading Behaviors Using Eye-Tracking Tobii Glasses

Description

HYPOTHESIS: 1. Horizontal convergence tracked with Tobii glasses is a reliable substitute for accommodation in young myopes and hyperopes with normal accommodative amplitudes 2. Young mypopes and hyperopes demonstrate different reading behaviors during near work AIMS \& OBJECTIVES: 1. Compare the accommodative responses measured with the Grand Seiko open-field autorefractor to those derived from the Tobii Glasses, when subjects wear (1) spectacle glasses, (2) single vision contact lenses (SVCLs), and (3) multifocal contact lenses (MFCLs). 2. Investigate subjects' natural and dynamic accommodative behaviors and eye postures during reading using the Tobii Glasses. 3. Compare the change in natural and dynamic accommodative behaviors and eye postures during reading between myopes and hyperopes using the Tobii Glasses.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • 2. Refractive error: Subjects with myopia between -1.00 and -5.00 D in each eye (n = 5), or hyperopia between +2.00 and +5.00 D in each eye (n = 5), determined by spherical equivalent using dry manifest refraction and binocular balance
  • 3. Astigmatism \<= 0.75 D in each eye
  • 4. Anisometropia \<= 1.50 D
  • 5. BCVA at distance 20/20 in each eye
  • 6. Habitual contact lens wears or willing to wear single vision and multifocal contact lenses during the 2nd study visit
  • 7. Normal eye posture and accommodation
  • 8. Good general and ocular health
  • 1. Strabismus at distance or near
  • 2. Amblyopia
  • 3. Significant anisometropia (\>1.50 D)
