Blurred vision generally occurs due to an eye condition. Here you can find more information about myopia, hyperopia, presbyopia, astigmatism and Age Related Macular Degeneration (AMD), all of which can cause blurry vision. However the underlying problem may be unrelated to the eyes – for example, a migraine or stroke.
Blurred vision is a symptom of many eye conditions. You should speak to your optometrist if you are experiencing problems.
Short-sightedness - Myopia is the inability to focus on distant items. You'll notice a problem if faraway objects appear blurred. Other symptoms include squinting, headaches and seeing halos around lights. It is an easily treatable condition with glasses or contact lenses generally correct the effects of myopia.
Age-related long-sightedness - Presbyopia is the hardening of the lens of the eye. You'll find you have difficulty focusing on nearby objects as a result. Presbyopia normally affects those over 40 years of age, and tends to stabilize around the age of 60. Other symptoms include headaches and eyestrain. Progressive lenses offer the best solution. Other solutions may include; varifocals, bifocals, multifocals, contact lenses or reading glasses.
Astigmatism - An irregular-shaped cornea means that some light rays are not focused directly onto the retina. Symptoms of astigmatism include blurred or stretched vision, eyestrain, headaches, squinting, difficulty driving at night. You should speak to your Optometrist about glasses, contact lenses or occasionally surgery.
Age-Related Macular Degeneration (AMD) - is a deterioration or breakdown of the eye's macula. The macula is a small area in the retina — the light-sensitive tissue lining the back of the eye. The macula is the part of the retina that is responsible for your central vision, allowing you to see fine details clearly.
