Part I: Scientific Features and Mechanisms of Action of Saffron on the Eye

Saffron (Crocus sativus L.) is recognized as one of the most valuable medicinal plants in the world. In recent years, it has attracted scientific attention due to its positive effects on vision and particularly on retinal health. The main bioactive compounds of saffron include crocin, crocetin, and safranal, which possess strong antioxidant and anti-inflammatory properties (Hosseinzadeh & Nassiri-Asl, 2013).

1. Antioxidant Effects

Oxidative stress plays a critical role in the degeneration of retinal photoreceptor cells and the development of age-related diseases such as age-related macular degeneration (AMD). Crocin, a water-soluble carotenoid, neutralizes free radicals and prevents damage to retinal cells (Bisti et al., 2014).

2. Protection of Photoreceptor Cells

Animal studies have demonstrated that saffron supplementation can reduce apoptosis in retinal photoreceptors, thereby preserving retinal function (Maccarone et al., 2008).

3. Improvement of Retinal Blood Flow

Crocin and crocetin contribute to increased retinal blood circulation and improved oxygen exchange, which strengthens the performance of visual cells (Liu et al., 2005).

4. Anti-Inflammatory Effects

The anti-inflammatory activity of saffron, mediated by inhibition of cytokines and inflammatory pathways, helps slow the progression of ocular diseases such as glaucoma and diabetic retinopathy (Poma et al., 2012).

Part II: Clinical Applications and Recommendations

1. Clinical Evidence in Age-Related Macular Degeneration (AMD)

Clinical trials have shown that daily intake of 30 mg saffron supplements for three months can improve retinal sensitivity and central vision in patients with mild to moderate AMD (Falsini et al., 2010).

2. Enhancement of Night Vision and Reduction of Eye Fatigue

Some human studies suggest that saffron can improve visual capacity under low-light conditions. This effect is likely due to enhanced photoreceptor activity and improved neural function in the retina. Regular consumption may also reduce eye fatigue induced by prolonged computer use (Broadhead et al., 2019).

3. Methods of Consumption

• Oral use: as saffron tea or added in small amounts to food.

• Standardized supplements: clinical trials typically use 30 mg/day.

• Topical use: currently, saffron-based eye drops are not officially approved; oral consumption remains safer.

4. Safety Considerations

Excessive intake of saffron (over 5 g/day) may cause adverse effects such as hypotension, nausea, or dizziness (Abdullaev, 2002). Patients with chronic ocular diseases should consult their physician before using saffron supplements.

Conclusion

Due to its antioxidant and anti-inflammatory compounds, saffron plays an important role in protecting the retina and improving vision. Scientific evidence demonstrates that controlled consumption of saffron may slow the progression of diseases such as AMD and enhance visual performance. However, its intake should be within safe dosage limits and under medical supervision.
