What to Check Before Ordering Boston Gas Permeable Lenses

Exact Boston Lens

Make sure the Boston lens name matches your prescription exactly. Boston ES, Boston XO, Boston EO, Boston XO2, Boston IV, Boston Equalens, and Boston Equalens II are different product names, so you should order only the one your eye doctor prescribed.

Wear Schedule

Review whether your prescribed Boston lens is for daily wear only or part of a different doctor-directed plan. Boston EO, Boston ES, Boston XO, and Boston XO2 are indicated for daily wear, while Boston Equalens II is the Boston material highlighted for overnight ortho-k use.

Fitting Details

Use the prescription and fitting details from your eye doctor before you order. Boston GP materials are used in specialized designs, so the fit, lens design, and wear instructions should match your professional fitting plan.
