Contact lenses cornea, permeable contact lenses, contact lenses farsightedness
People suffer from various eye conditions which do not allow them to use regular contact lenses. They require specially designed lenses to rectify their problems and have a better eye sight. The several eye conditions which needs specially designed contacts are
• Giant papillary conjunctivitis
• Dry Eyes
Lenses Required For Astigmatism
Astigmatism can be corrected by specially designed toric lenses. Fitting the regular soft contacts for farsightedness or nearsightedness is easier than the fitting of toric lenses. The toric lenses should move constantly while blinking keeping the alignment correct and without any rotational movement. These lenses provide the best possible comfort, fit and correct vision.
Toric contacts are available in soft as well as GP lens material. People suffering from unusual amount of astigmatism require custom designed contact lenses. The custom made lenses are costlier than the regular toric contact lens.
Another option for astigmatism is hybrid contact lens. These lenses provide the clarity of a gas permeable lens but the comfort of the soft lenses.
Contact Lens for Presbyopia
Monovision and bifocal lenses are options for presbyopia. Multifocal and bifocal lenses have a complex design than the regular contact lenses. The important thing is the fitting of these lenses. A proper fit will ensure good vision. Finding the correct contact lens for presbyopia is costlier and even time consuming.
The result derived from bifocal and monovision lenses are worth the money and time spent.
Contact Lenses for GPC
GPC or Giant papillary conjunctivitis is an inciting reaction which is the result of proteins secreted in the tears. Due to this reaction the lid glands secrete substances which create a transparent coating on the lens. This makes the contact lens uncomfortable and further creates problem in vision.
Soft daily disposable lenses can solve this problem because they do not allow accumulation of any protein deposit. It is only possible because these lenses are discarded daily.
GP contact lens is another good option for GPC. There is no chance of any allergic reaction if one wears gas permeable lens for it requires cleaning daily.
Contacts for People Suffering from Dry Eyes
Chronic dry eyes are very common eye condition with most people. This is one of the problems that do not allow people to wear contact lenses. People are even asked to discontinue wearing the contact lenses because of dry eyes.
Few dry eyes symptoms are:
• Tearing without any reason
• Excessively watery tears
• Constant feeling of something present in the eye
• Burning eye or frequent red eyes
Soft lenses may not be the solution for chronic dry eyes. In order to solve this problem, you require the new soft contact lenses. These contact lenses hold moisture better than the regular soft lenses even after wearing it for a long period of time.
Gas permeable lens is also another option for dry eyes because they do not absorb moisture as the soft lenses. Dry eyes can also be treated through punctual plugs. These may even improve the comfort of a lens.
