Many people hardly do anything to take care of their eyesight until something happens to threaten it.
Ophthalmologist with Cleveland Clinics, Dr . Richard Gans, explains the five most common conditions affecting people’ s vision, and shares tips for preserving your eyesight.
The problem: Light rays from objects in view must pass through your lens to reach your retina ’s light- sensing cells. When a cataract clouds the lens, your vision fogs and lights get a halo .
Tips for prevention: Protect your eyes with lenses that block both UVA and UVB light, and avoid smoking . It’s important to control your blood pressure , watch your weight and manage diabetes as well .
The problem: Your retina transforms light into signals your brain can process . Diabetes can swell the retina and make blood vessels leak or grow, causing blurring, flashes , floaters, pain and pressure .
Tips for prevention: Get yearly dilated eye exams to detect diabetic eye problems early , which can prevent or slow vision loss . Controlling your blood glucose and blood pressure is also key .
The problem: You rely on light- sensing cells in the macula, the centre of your retina, for what is called central vision. In age – related macular degeneration, tissue breakdown or blood vessel growth in the macula makes it hard to see faces , read , drive and more .
Tips for prevention: Avoid smoking , which doubles your risk of macular degeneration as you age . Get regular exercise , control your blood pressure and cholesterol. Also, eat lots of leafy greens and fish.
The problem: The right amount of fluid must fill the space within your eye . Pressure from too much fluid damages the optic nerve , stealing your peripheral, and then your central, vision .
Tip for prevention: Work with your eye doctor to keep your eye pressure well -controlled to avoid losing your vision .
The problem : Your eyeball , cornea and lens must be shaped just right for light rays to bend ( refract) and land on your retina to make their way to the brain. If this process doesn’t happen, vision blurs .
In refractive errors , light rays do not bend and land where they should in the eye . Refractive errors include : myopia and hypermyopia
Tip for correction : Visit an eye specialist for corrective lens. This requires frequent medical attention
