Do You Need A Special Eye Exam For Contact Lenses?
You might be asking why contact lens exams are more expensive than normal eye exams if you're thinking about switching from glasses to contact lenses. Please remember that a prescription for eyeglasses will not evaluate how contact lenses will fit. This is why a routine eye checkup cannot replace a good contact lens prescription. A contact lens examination, on the other hand, includes all of the procedures and testing necessary to find the ideal contact lenses for you.
A full eye exam is required to obtain an eyeglass prescription. Vision acuity, ocular coordination, prescription strength, and fluid pressure will all be assessed by your doctor. Your doctor may also dilate your pupils to check for more significant health problems.
Because contact lenses fit directly on the eye, prescribing them is more difficult. Eyeglasses, on the other hand, are around 12mm away from the eyes, implying that they will have higher power than contacts. Exams for eyeglasses determine eyesight and how much, if any, refraction correction is required. Doctors must not only measure real power but also the curvature and width of the cornea during contact lens checkups. Exams for contact lenses also check for the best fit and suitable size. A doctor may also perform a tear film evaluation test on first-time contact lens wearers to see if their eyes generate enough tears to wear contact lenses.
Comfort is crucial when it comes to contact lenses. An optometrist will most likely give you a pair of trial contact lenses to see how they fit. This necessitates a follow-up appointment to check that the lenses are properly fitted and comfortable. Contact lenses that aren't properly fitted might have a negative influence on your eyes' general health.
When undergoing an eye test, think about whether you'll need a contact lens prescription in addition to an eyeglass prescription. This necessitates more time to conduct further testing. It's a good idea to have the same eye care professional complete both the general and contact lens exams so you don't have to go through the same steps twice.
