The purpose of this study is to investigate how focusing the eye affects the quality of retinal images in peripheral vision. Peripheral vision refers to the part of vision that occurs outside the very center of gaze and is important for activities such as driving and navigating through spaces.

Participants in this study will undergo procedures to assess the quality of their retinal images while focusing their eyes. This will involve specific tests where the eye's focusing ability is measured and analyzed.

• Who can participate: Participants should be within a specific age range and may need to meet certain health criteria related to vision and eye health. Individuals with certain eye conditions may be excluded.
• Study details: Participants will focus their eyes during tests designed to measure the quality of retinal images in peripheral vision. This will help understand the relationship between eye focusing and vision clarity.
