Hereditary and is usually present from birth.May develop following an eye injury or eye surgery.It can occur due to a relatively rare condition called keratoconus in which the cornea becomes progressively thinner and cone-shaped.It can decrease or increase over time.Blurred vision at any distance.Eye discomfort.Headaches.A doctor of optometry can diagnose astigmatism through a comprehensive eye examination. Testing for astigmatism measures how the eyes focus light and determine the power of any optical lenses needed to improve vision. This examination may include: 1. Visual acuity. When you read letters on a distance chart, you are measuring your visual acuity. Vis...
Eyeglasses. People with astigmatism primarily choose eyeglasses to improve their vision. The eyeglasses contain a special cylindrical lens prescription that compensates for astigmatism. This provid...Contact lenses. Some people will have better vision with contact lenses rather than eyeglasses. Contact lensesmay provide a clearer vision and a wider field of view. However, since contact lenses a...Orthokeratology. Orthokeratology (ortho-k)involves the fitting of a series of rigid contact lenses to reshape the cornea. The patient wears contact lenses for limited periods—such as overnight—and...Laser and other refractive surgery procedures. Astigmatism can also be corrected by reshaping the cornea through LASIK (laser in situ keratomileusis) or PRK (photorefractive keratectomy). PRK remov...Since astigmatism is an abnormality of the regular anatomy of the eye, there is nothing that can be done to prevent it from occurring. However, as stated above, there are many treatment options.
Ocular allergies are the abnormal response of sensitive eyes to contact with allergens and other irritating substances. Often negatively affecting quality of life meriting consideration for customized treatment plans instead of one-size-fits-all, over-the-counter (OTC) relief.
Glaucoma is a complex disorder of aging defined by the death of reti-nal ganglion cells and remodeling of connective tissues at the optic nerve head. Intraocular pressure-induced axonal injury at the optic nerve head leads to apoptosis. Loss of retinal ganglion cells follows a slowly progressive sequence.
Inspired by real capabilities of the human eye, the AOA created a conceptual product to showcase the immense power of our eyes and underscore the need to care for unparalleled technology we already have – our eyes. Visit SeeTheEye.com to learn more.
