Have you ever noticed small spots, threads, or cobweb-like shapes moving across your vision? These are called eye floaters. Flashes of light may also occur when the vitreous, a gel-like substance inside the eye, pulls on the retina. What Causes Floaters and Flashes? Floaters commonly develop with ageing as the vitreous changes. Many are harmless, but a sudden increase in floaters or new flashes can indicate a retinal tear or retinal detachment. When Are They Dangerous? Warnin

Age-related macular degeneration (AMD) is an eye condition that affects the macula, the central part of the retina responsible for detailed vision. It is more common in older adults and can make activities such as reading, recognizing faces, and driving increasingly difficult. What Are the Symptoms of Macular Degeneration? Common symptoms include blurred central vision, difficulty reading small print, straight lines appearing distorted, and difficulty recognizing faces. Some

Some childhood eye conditions may not cause obvious symptoms, making regular vision assessments an important part of children's healthcare. Common Eye Problems in Children Children may develop refractive errors such as short-sightedness, long-sightedness, or astigmatism. Other concerns include squint, amblyopia (commonly called lazy eye), and certain eye alignment or developmental

The retina is a thin layer of light-sensitive tissue located at the back of the eye. Retinal detachment occurs when this tissue separates from its normal supporting position. Without timely treatment, it can lead to permanent vision loss. What Are the Warning Signs? Important warning signs include a sudden increase in floaters, flashes of light, a dark shadow across the field of vision, or a curtain-like effect. Some people may also notice sudden blurred vision.
