Among children and adults, astigmatism is a common vision problem. It can affect anyone irrespective of whether the person has myopia or presbyopia, or wears contacts or glasses. But, there is ray of hope also. Astigmatism gets corrected easily. With the help of an exact prescription for contacts or glasses for astigmatism will solve the problem.The reason behind astigmatism is an uneven or oddly shaped cornea. Generally the shape of cornea is spherical, but in case of astigmatism it is oblong or oval. The causes behind astigmatism are a) Heredity - it is in your DNA b) eye injury c) eye surgeries d) thinning of the cornea. Due to it, the vision gets blurred and if left unattended, may cause headaches and strain to eyes.Astigmats must regularly schedule eye checkups because if not corrected it will worsen over time. Therefore, take proper care and change the prescription for glasses or contacts as per the need. Contacts and glasses - both are capable to correct astigmatism. Sometimes, it becomes so severe that eye doctors don't allow usage of contacts but such cases hardly take place.Earlier, astigmats had only three choices: 1) wear glasses, 2) wear hard or rigid GP lenses, 3) live with it.But, today Acuvue contact lenses, the most popular brand from the house of Johnson & Johnson contact lenses - the giant in the contact lens industry, have come up with two great varieties in toric lenses. Same materials are used in these lenses like other regular lenses but the design is different. Instead of moving inside the eye, these lenses stay in place when eyes are moved to look around.One kind of toric lens is Acuvue Advance made with Hydraclear technology resulting into more comfort and no dryness in eyes. The edges of the lens are made consistently thin, with the help of Accelerated Stabilization Design, to allow less movement of the lens when the user blinks.The other kind is Oasys lenses. Both Hydraclear technology and Accelerated Stabilization Design are used in this lens also. These lenses get properly repositioned automatically by themselves if they get move out of place. As these lenses allow five times more oxygen to the cornea, therefore they can be worn for consecutive six nights and seven days.Both eye examination for astigmatism and the lenses are quite costly but the convenience and correction it provides is worth it to many astigmats.And, now let me help you with buying part.
