To convert your glasses prescription to a contact lens prescription, consult your optometrist for precise measurements. Online calculators can offer basic estimates. Remember, the vertex distance impacts the conversion. For the best results, rely on professionals and trusted sources. Accuracy is key in adjusting prescription parameters.
First, you’ll need your glasses prescription, which includes sphere (SPH), cylinder (CYL), axis, and pupillary distance (PD). The sphere value measures the degree of nearsightedness or farsightedness. Cylinder and axis values indicate astigmatism. However, contacts require additional measurements such as base curve and diameter, which help determine the fit of the lenses.
For accurate conversion, consult with an eye care professional. They can provide specific measurements and make necessary adjustments to your sphere and cylinder values. Optometry clinics often offer free consultations to assist with this process.
Various online tools and resources are available for additional guidance. Websites like the American Optometric Association provide comprehensive information. The next steps involve selecting the right contact lenses and understanding proper usage and care for your specific needs. This information is vital for achieving optimal eye health and vision clarity.
