# What causes smoky vision?

Smoky vision is a description patients use for grey, hazy sight as though looking through smoke. It can signal problems with the ocular media or retina.

## Underlying Causes

Vitreous haemorrhage, inflammatory cells within the vitreous, and dense cataract often create a smoky or fog-like impression. Corneal scarring or advanced macular disease may similarly reduce contrast and colour saturation.

- Sudden smoky vision with floaters can indicate bleeding from retinal vessels
- Chronic macular degeneration gives slow decline and desaturated colours
- Tobacco smoke exposure can worsen surface irritation and perceived haze
- Systemic vascular disease and diabetes are common risk factors for intra‑ocular bleeding

## Assessment

Dilated examination and imaging such as ultrasound or OCT help distinguish between vitreous, lens, and retinal causes. Management may range from observation to injections, laser, or surgery.

- Emergency evaluation is needed when smoky vision follows sudden floaters or trauma
- Optimising systemic control reduces recurrence of vascular causes
- Low‑vision aids can improve function when residual haze persists
- Smoking cessation benefits both ocular and general health
