A lot of people think that they can’t wear contact lenses because of their astigmatism. For mild astigmatism, GP lenses and hybrid contact lenses are recommended. They both provide sharper vision than soft lenses do. It is very important to visit an ophthalmologist before trying these lenses for better guidance.
Different Types of Contact Lenses for Astigmatism
Toric contact lenses or soft contact lenses that correct astigmatism. It is made out of hydrogel material that is either conventional or silicone. There is a difference between the regular soft contacts and toric lenses for astigmatism. The regular soft contacts correct myopia or hyperopia while toric lenses correct the amount of nearsightedness and farsightedness in the eye that has astigmatism. It also enables a clear vision by enabling the alignment of the lens to the proper orientation of the cornea.
The exam and fitting of contact lenses differ since it takes more expertise and costs more than the regular ones because of its complex design. The cost also differs from the material of the lens and the brand of it.
Rigid gas permeable contact lenses or RGP or GP contact lenses are another type of contact lens for astigmatism. Some lenses can correct without toric design because it retains its shape on the eye, unlike soft lenses that conform to the irregular shape of the cornea. For individuals who have a high amount of astigmatism, there is a toric design available in GP lenses. Another variety is scleral lenses which are large-diameter gas permeable contacts that correct astigmatism even with irregular corneal surfaces.
They usually prefer RGP lenses even if it takes more time to get used to because it provides a sharper vision than toric soft contact lenses. A professional prescription is needed for an RGP contact lens because of its custom-made parameters which make it cost more.
Hybrid contact lenses are said to be the best choice as contacts for astigmatism because of the comfort and sharp vision it provides. It is a combined feature of sharp vision of GP lenses and comfort of toric soft lenses. There is also a small risk of contacts being withdrawn during physical activities. The procedure of fitting is almost the same with GP lenses.
Exclusive Contacts for Astigmatism
Disposable contact lenses for astigmatism are now available, it can be daily, weekly, or monthly replacement. Color contact lenses with toric designs are also available which enhances your eye color and toric bifocal contact lenses correct astigmatism and presbyopia. Overnight wear of contact lens is also possible with toric silicone hydrogel lens.
Consult Your Doctor First
It is important to have a comprehensive eye exam and consultation first before wearing contact lens. Your eye doctor can help you to choose what is perfect for your specific eye needs such as an astigmatism-correcting contact lens.
