Advancement in technology has led to development of soft contact lense that is more reliable as compared to past hard lenses. This new lenses have certain features that lack in the hard lenses. They are made using high quality hydro gel and silicone that allows sufficient passage of oxygen to the eye hence providing more comfort and convenience that could not be derived from hard lenses. Let’s see some of the major differences between these two types of lenses.
Soft Vs Hard Contact Lenses
Coverage and water content– Soft lenses have capacity to provide the much needed coverage due to the fact that their edges firmly rest on the sclera. They fit naturally in the eyes since they are more flexible as compared to the hard lenses. They have approximately 30-80% water content that is very helpful in shortening the adjustment period as persons switch from wearing eyeglasses.
Lowered risks of Irritation– Patients who have used the hard lenses have experienced eye irritation which in turn negatively affects performance and productivity. Soft contact lenses’ design has incorporated a thick cling film that effectively keeps away foreign particles that cause irritation when they get stuck between the cornea and lens.
Require more care and frequent replacement– Unlike hard lenses; users of soft lenses have to carefully take care of their lenses so as to prevent damage. It’s medically advisable to regularly replace them so as to avoid other complications that may result as some of the features become less effective. Some of the practices that need to be carried out include regularly cleaning and disinfection so as to eliminate any pathogens that may aggravate the vision problem.
In order to meet the diverse needs and preferences of clients the manufacturer has made soft lenses in different designs so as to solve the specific vision problems experienced. Some of the common designs include:
- Spherical – These types of lenses are usually rounded, most suitable for correcting short (myopia) and long (hyperopia) sight problems.
- Toric – This design can be used to correct myopia, hyperopia and astigmatism.
- Bifocal – This soft contact lense contain varying zones for far and near vision and are most effective in treating presbyopia.
- Orthokeratology – They are specifically designed to reshape the cornea when user is asleep hence increasing time spent during the day without the lens.
- Dry eyes contacts– This yellow contacts are specifically designed to reduce problems related to dry-eye symptoms.
- Custom Lenses-This are yellow contacts are made as per the needs and specifications of the user. They are designed to solve a specific problem; however they may be a bit expensive as compared to the already made soft contact lense.
- Ultraviolet Inhibiting Lenses– Degradation of ozone layer has led to increased penetration of UV rays which may negatively affect eyes resulting in cataracts. This UV inhibiting lenses are designed to effectively protect users from this rays.
Choosing the right contacts may be an uphill task if one does not have the necessary information. Select lenses that will effectively solve the problem so as to avoid wasting resources on products that don’t solve the problem. For Example one can choose a daily disposable lens that has to be replaced every day or weekly. Ensure that the lenses fit well in the eye so as to avoid discomfort and other complications. One can also seek professional advice from health personnel on the most suitable lense to use. Be sure to purchase this product from accredited soft contact lense suppliers.
