2. Your prescription may need to be adjusted
The fit could be off
Your contact lenses need to fit the unique shape of your eyes. If they don’t, they may not stay put or be as effective as you’d like. If the fit of your lenses is wrong, an eye doctor will need to refit you during a contact lens fitting exam.
Prescriptions can change
As you get older, your eyes change, and in turn, your vision may change too. If this happens, your near vision may become blurrier. Always be sure to schedule your yearly eye exam to update your prescription and check on your eye health.
Contact lenses may not come in your exact prescription
It’s also important to understand that your eyeglasses prescription isn’t always directly translatable to contacts. Glasses can be made to precisely fit your prescription, while contact lenses are typically mass produced, which may mean you don’t get your exact prescription (though they’re designed to fit most prescriptions, so this problem is relatively rare). For example, if your glasses prescription is +7.25, you might only find +7.00 or +7.50 in contacts. If this is the case, your eye doctor may need to try a few different strengths to see what works best for you.
