Background: To determine the normative data and reference value for photostress recovery time (PSRT) following exposure of the macula to light, in various age groups within the Indian population.
 Methods: Cross-sectional observational study performed from November 2015 to July 2016 in the Bangalore district of Karnataka state in India. We examined a total of 1,282 eyes of 641 participants and included those with corrected distance visual acuity (CDVA) scoes lower than or equal to 0.4 Logarithm of the Minimum Angle of Resolution (LogMAR). We performed the photostress procedure under standard conditions using the same approach.
 Results: The mean ± standard deviation (SD) of the participants’ age was 32.04 ± 15.80, with an age range of 8 to 70 years. The PSRT in participants below 16 years and above 45 years of age were significantly different compared to the 16–25-year-old age group (P < 0.0001 for both). The PSRT values were significantly different between males and females in the reproductive age group (16 to 45 years old) (P < 0.0001), but not in the other age groups.
 Conclusions: The PSRT values were significantly different in children and older patients compared to the 16 to 25 years age group. We found that as age increased, PSRT increased significantly.
