An optometrist doesn’t just fit customers for glasses. The optometrist office can also determine if you’re a good candidate to wear contact lenses. There are contact lenses that customers choose simply to change their eye color. Even though these are purely for aesthetic purposes, the optometrist should still also do an eye exam because not everyone can wear the same kinds of contact lenses. For example, not all patients can use soft lenses and not all customers can wear soft lenses. There are also lenses that you can wear for several weeks at a time. The optometrist will determine the best kinds of lenses for the shape of your eyes and the right lenses for the Williamson County TN Contact Lens schedule that works for the patient’s lifestyle.
If you need corrective lenses, you can also get contacts that correct your vision just like eyeglasses do. You might need a Williamson County TN Contact Lens prescription that corrects conditions like astigmatism, presbyopia, hyperopia, or myopia. There are even contact lenses that function like a bifocal eyeglass lens does; they accommodate two prescriptions within the same lens for both distance vision and seeing objects up close.
The wear schedule varies from daily wear lenses, which are taken out when the patient goes to sleep, to extended wear, which are worn as long as six nights in a row, and continuous wear lenses, which can be worn for as long as 30 days at a time without taking them out. Both extended wear and continuous wear lenses allow oxygen to permeate the lens to reach the cornea. If a patient leaves a daily wear lens in for sleeping, not enough oxygen will reach the cornea, and this can result in an eye infection or a corneal ulcer.
Patients should take care of their lenses and treat them as they were taught at the optometrist’s office. Using careful hygiene can prevent eye infections. The wearer should wash their hands before touching the lenses and then rinse them under running water and inspect them for scratches or debris before inserting them. There are different techniques for inserting and removing soft and rigid lenses, so patients should follow their doctor’s instructions.
