There are many people who will have a certain eye condition that can make it more challenging to wear contact lenses. For this reason, it is important to see an eye doctor to determine if you have a specific type of eye condition. It will also ensure you get the right contacts if you choose to order your contacts from an online contact lens retailer. Below is a list of common eye conditions that will require a specific type of contact lens:
Astigmatism: Today, millions of people suffer from astigmatism. This is a condition where the curvature of the front eye is not even but has an oval or bulge shape. The result is part of the eye curve is steeper than the remaining area of the eye. People with astigmatism will have blurred vision. The contact choice to resolve this problem is called toric contact lenses. These contact lenses are designed to fit on the eye so they do not rotate because the corrective power must be aligned with the bulge .Gas permeable lenses are often the choice to correct astigmatism. Toric lenses are normally custom made for each patient.
Dry Eye: This condition will feel gritty in the eye like there feel like a particle in the eye. There can be blurred vision, redness, and also a burning feeling. There are ointments, artificial tears, and medicated eye drops that can be used to treat dry eye. It is advantageous to wear daily wear contacts. So that you take them out each day to allow the eye access to oxygen and you can treat the eye.
Giant Papillary Conjunctivitis (GPC): This condition occurs as the result of an inflammatory reaction that occurs on the inner surface of the eyelids. It can be caused by the accumulation of protein on the contact lens. It may be helpful to wear daily disposable contact lens or daily wear contact lens so that you can use protein removing solution every night and let them sit in lens disinfection solution over night. Gas permeable lenses are another choice as the protein in tears does not stick as easily to these lenses.
Keratoconus: This is a condition that results in thinning of the cornea causing the eye to bulge forward resulting in a cone shape. The most common treatment for mild to moderate keratoconus are gas permeable contact lenses as they can help control the bulging while improving vision. Hybrid contact lenses are another choice for people suffering from keratoconus. The lenses combine the clarity and rigidity of a gas permeable center with a comfy soft ring around it.
Presbyopia: Often resulting from the aging process, the condition causes one to lose focus on close objects. Many bifocal and multifocal lenses are available such as monovision lenses which are when one eye is fitted for near vision and the other for distance vision.
The cost of hard-to-fit contact lenses can be more expensive than regular contacts; however, patients can find greatly discounted special contact lenses from online contact lens retailers. A reputable online contact lens retailer will have a wide variety of brand name contact lenses available to suit many eye conditions. The best way to learn about your eye health is to see your eye doctor so you can have the appropriate eye exam and tests.
