There are many lens manufacturers in the current times. Each lens manufacturer has unique features that make them best for different people. There is no one lens manufacturer that can cater for the needs of all people. About 90% of the contact lenses that are prescribed in the U.S every year are soft lenses. However, before you get a soft lens, there are some factors that you should consider to ensure that you get the best one for you.
The first consideration that you should make is the base curve. This is the primary curve (fitting) that is found on the back of the lens. The base curve should almost the same as the curvature of your cornea. If the lens conforms well to the cornea, its surface will be smooth and will provide you with vision that is not distorted. During the lens fitting, the eye professional will choose the base curve that best fits your cornea.
The diameter of the lens is another very important consideration that you should make as it determines your comfort. Depending on the shape of the eye you might needs a lens that has a large diameter so that it centers just right on your cornea. The opposite of this is true. If you have a smaller cornea, then you will need a lens diameter that is equally as small.
Different lens manufacturers make lenses with varying power ranges to cater of myopia and hyperopia. If you need a strong correction, then these lenses are best. The power that you get will depend on the level of correction that you require.However, if you have what is referred to as astigmatism, then you will need a toric contact lens that ensures that your toric powers are properly aligned as well as reduce the rotation of the eye when you blink and change the head position. If you have this condition, you will have to consider several other things apart from the base curve and the diameter. The tightness of the eyelids come into play and determine the kind of toric lens that you will get.
If you have dry eyes, wearing a lens may get pretty uncomfortable after a while. As such you will need to moisten them after some few hours. Lenses that feature these treatments might be the best for you.
For the most part, the very first contact lens that your specialist chooses for you is the best. But in some occasions, you might have to try several before you find the perfect one for you.
