Specifying and controlling the optical image on the human retina

Area of Science:

• Ophthalmology
• Optical Engineering
• Visual Neuroscience

Background:

• The understanding of the retinal image has evolved from basic optical models to complex intra-retinal phenomena.
• Current knowledge integrates schematic eye models, image characterization, and quality control procedures.

Purpose of the Study:

• To review the historical development and current state of knowledge regarding the retinal image.
• To cover schematic eye models, retinal image properties, quality control, and intra-receptoral optics.

Main Methods:

• Literature review of trends in visual optics and retinal imaging.
• Analysis of schematic eye models and first-order optics.
• Examination of methods for retinal image access and characterization.
• Review of retinal image quality control procedures.
• Discussion of intra-receptoral optical effects.

Main Results:

• Established schematic eye models define the retinal image using first-order optics.
• Methods exist for characterizing the actual retinal image.
• Procedures for controlling retinal image quality are available.
• Intra-receptoral optics introduce discrepancies between retinal surface light and photopigment interaction.

Conclusions:

• The field has progressed significantly in understanding the optics of the eye and the retinal image.
• Further research into intra-receptoral effects is crucial for a complete understanding of visual perception.
