How To Choose The Best Contact Lenses
Soft contact lenses are often the first recommended contact lenses for patients. They are used to correct a variety of vision issues, including:
As opposed to conventional hard lenses
soft contacts are generally less uncomfortable and easier to wear. There is also a wide range of choices when it comes to the materials that are used in gas-permeable lens systems. The most popular ones are composed of gas-permeable silicone, and the most comfortable are the gas-permeable polycarbonate lenses.
The biggest advantage of soft contacts
is that they provide greater comfort than their hard counterparts. Because soft contacts do not contain any gas, there is no chance that bacteria will grow on the surface of the eye, which can irritate the eyes and lead to discomfort and even infections. Since oxygen is absorbed by the eye through the cornea, it must be within the patient’s eye for optimal vision. Since oxygen deprivation leads to discomfort, many optometrists prefer using soft contacts.
In addition to providing greater comfort
some researchers have found that soft contact lenses can be more effective at correcting vision than conventional ones. A particular theory put forth by neurologists is that when the light touches a soft cornea, or if it has a gentle pressure applied, the eye can sense it and respond as if it were a light touch. This allows the eye to focus on nearby objects, which can result in better visual acuity.
Another advantage of soft contact lenses
is that they are available in a variety of styles, depending on the patient’s needs and comfort level. For instance, there are daily wear lenses, which are recommended for people who do not need corrective contact lens therapy every day. Soft contact lenses may be worn during sleep, while watching TV, swimming, exercising, gardening, and working out. These lenses may be comfortable to wear all day long but should be removed and cleaned daily. Therefore, the optometrist must recommend the correct type and frequency of daily cleaning, which should include both protein and oil cleansing.
Some people find that they benefit most from wearing a pair of soft contact lenses
over their conventional hard lenses, especially those who cannot wear traditional hard contact lenses because of potential problems with dry eyes. Others find that they prefer the flexibility that contacts provide. Daily wear, rigid gas permeable lenses, and soft PMMA are all options that a patient can consider. To find the best solution, the patient must consult an optometrist who can determine his or her individual needs and provide advice on which option would be most beneficial for him or her.
