Research in an MRI environment does not allow for participants to wear regular eyeglasses. Therefore, ensuring participants are able to comfortably see the visual display while inside the MRI is crucial and requires a vision correction system. These MRI Vision Correction Lenses ™ provide an MRI compatible system including frames and lenses. Lense corrections are available from +2 diopters to +7 diopters in ½ diopter increments. MRI Vision Correction Lenses ™ is intended for research use only.
