Do You Need Glasses for Contact Lens Prescription?

Transitioning from glasses to contacts can be a significant change, often leading to questions about the necessity of having both simultaneously. It is generally advisable to have a pair of glasses with the same prescription as your contact lenses. This article will guide you through the procedure of getting contact lenses prescribed, the role of eye exams, and why having both glasses and contacts is beneficial.

Why Glasses Before Contact Lenses?

Though it is not strictly necessary, it is often recommended to have glasses processed before beginning the contact lens fitting process. The first step is to visit an eye doctor for a comprehensive examination.

Part One: The Health Assessment

The initial part of the eye examination involves a health assessment. This critical step includes:

Checking if the eyes look healthy with everything in the correct place. Identifying any potential diseases or issues within the eyes. Evaluating if the eyes work together effectively. Checking the pupil's reaction to light appropriately. Assessing the peripheral vision to ensure it is functioning correctly.

Part Two: Refraction and Correction

Following the health assessment is the refraction, which determines the degree of your vision correction. The refraction for glasses and contacts is slightly different, as contact lenses rest directly on the cornea, while glasses are a short distance away. The refraction process includes:

Determining the level of refractive error and the clarity of vision based on the Snellen chart (commonly used in the US and other countries). Identifying whether you need lenses (contacts or glasses or both) to achieve better vision clarity. Making a prescription for glasses and contacts, which accounts for the different placement. Evaluating the size, type, and curve of the contacts needed. Calculating the degree of correction required for contact lenses.

Typically, there is an additional charge for a contact lens fitting. This is because the fitting process for contacts is more intricate, taking into account the individual's eye health, age, and specific vision needs.

Alternatives and Emergencies

There will always be instances where you may need glasses more than contacts. Contact lens emergencies can and do happen, such as losing a lens, experiencing discomfort, or dealing with a physical issue like an eye injury. Having a spare pair of glasses ensures you can see clearly during these unpredictable situations.

Always keep a spare pair of glasses with the same correction as your contacts at hand. This ensures that you are prepared for any eye-related challenges that may arise and that you can maintain your vision clarity without delays.

Conclusion

While glasses are not a strict prerequisite for getting contact lenses, they play a crucial role in your vision journey. A thorough eye examination, including both the health assessment and refraction, provides you with the necessary information to make an informed decision about your vision correction options. Keeping a spare pair of glasses with the same prescription as your contacts is a wise precaution, as it ensures you can see clearly in different situations and emergencies.
