Light is essential to human health, but modern exposure to artificial blue light—from screens and LEDs—can disrupt sleep, strain the eyes, and affect long-term wellness. This blog explores how blue light influences our circadian rhythms, eye health, and overall well-being, and offers practical, evidence-based tips to reduce its negative impact.

In Optic Nerve and Glaucoma: Time for a Paradigm Shift, Dr. Keshav Narain challenges the long-held belief that intraocular pressure (IOP) is the sole culprit in glaucoma. Drawing from decades of clinical insight and emerging technologies like electrophysiology and microperimetry, this piece highlights a critical evolution in how we diagnose and manage the disease. With tools like Visually Evoked Potentials (VEP) and Selective Laser Trabeculoplasty (SLT), clinicians are now fo

If you’re dealing with red, irritated eyelids, crusting on your lashes, or that persistent gritty sensation in your eyes, you might be experiencing blepharitis—and microscopic mites could be the cause. In this blog and podcast, Dr. Keshav Narain explores the role of Demodex in this common eye condition, how it affects your eyelids, and what you can do to manage it. Learn the science behind the symptoms and discover effective treatment options to get lasting relief.

Illustration of the human eye showing the retina, optic nerve, and macula, with highlighted areas of retinal ganglion cell loss in glaucoma and photoreceptor degeneration in macular degeneration. Arrows indicate neuroprotective strategies like neurotrophic factors, medications, and electrical stimulation targeting these retinal layers.

Can eye supplements really protect your vision, or is a healthy diet more effective? In this post, Dr. Keshav Narain breaks down the findings from the landmark AREDS1 and AREDS2 studies—explaining when supplements help, when they don’t, and why leafy greens might be your best defense against macular degeneration.

In this third episode of our podcast series on Idiopathic Intracranial Hypertension (IIH), we delve into one of the most important aspects of managing the condition: weight management. IIH is a complex neurological disorder characterized by elevated pressure around the brain, often causing headaches, visual disturbances, and other symptoms. Despite its name, the condition isn’t truly "idiopathic" anymore — emerging research is shedding light on the underlying mechanisms, par

Selective Laser Trabeculoplasty (SLT) was first developed in the late 1990s by Dr. Mark Latina and Dr. Park as a novel approach to lowering eye pressure in glaucoma patients. Originally introduced as a second-line treatment to eye drops, SLT has evolved into a preferred first-line therapy for many types of open-angle glaucoma.
