Answers to common questions about Coleyes Birkin Brown yearly prescription contacts, from fit and color effect to care and replacement.
Birkin Brown prescription contacts: common questions
- Will Birkin Brown look natural on my eye color?
- The catalog notes that lenses on different eye colors will show different effects, and pictures are for reference only. So the natural brown result depends on your own eye color and the lighting. The 13.0mm graphic diameter is a moderate size that can give a soft brown enhancement without a dramatic ring, but you should expect some variation from the product photos.
- What prescription powers are available for Birkin Brown?
- The supplied product record lists only a Standard variant and does not include a prescription range. Before ordering, check the live product page for the available powers or contact the store to confirm your prescription can be filled.
- How do I know if the 8.6mm base curve will fit?
- The base curve is 8.6mm, which is a common contact lens curvature. Fit is individual, so this measurement alone does not guarantee comfort. If you have not worn this brand before, have your eye care professional confirm that the lens parameters suit your eyes.
- What is included with a pair of Birkin Brown lenses?
- Each order includes one pair of lenses (two lenses) plus one lens case. You will still need your own contact lens solution and a case for daily storage if you prefer a different case.
- How often should I replace yearly Birkin Brown lenses?
- The period of use is one year. Replace them according to that schedule and your eye care professional's advice. Do not extend wear beyond the stated period, and stop using them if you notice discomfort or changes in vision.
- Can I sleep or swim in these lenses?
- The supplied information does not include instructions for sleeping, swimming, or other specific activities. Follow the general guidance from your eye care professional and the lens manufacturer's instructions for safe wear.

What the catalog does not tell you about care and compatibility
The supplied record does not include a cleaning or storage routine, nor does it list compatibility with specific solutions. Because these are yearly lenses, you will need a care regimen, but the exact steps should come from your eye care professional or the manufacturer's instructions rather than from general assumptions.
Similarly, the record does not confirm whether these lenses are suitable for people with certain eye conditions or for occasional versus daily wear. If you have any doubt, ask a professional before ordering.
