If you have not heard much about aspheric contacts, they are usually prescribed for people who have borderline astigmatism. They are far from the most common type of contact lenses as they tend to be suitable for a smaller proportion of the population. They are also sometimes prescribed for those people who have mild presbyopia.
One of the major advantages of these aspheric contacts is that they are generally quite thin. They will adapt better to the shape of the eye and that provides a greater level of comfort. They offer an excellent balance between visual acuity and ease of use. Most people who can afford to get these will tend to stick with them until their prescription requires otherwise.
That leads into one of the disadvantages. These are going to be more expensive than other contact lenses in most cases. It may be possible to mitigate that cost by getting extended wear aspheric contacts.
These now come in a wide variety of different versions and you can find something that will be suitable for you. Because of the cost, there is not a huge selection of short term disposables but you can find them if you got the budget for it.
Perhaps because you will be paying more, you would be wise to keep up with your prescription more diligently than you normally would. That’s always good advice, but when it comes to buying a more expensive type of contact, then you would not want to be purchasing ones you cannot use.
In many cases, you can save on contact lenses particularly online if you buy in larger quantities. Having an up to date prescription would allow you to get the best deal possible. You might be able to save enough money to enjoy the comfort of aspheric contact lenses.
