Executive Summary: Vision Benefits: What Employers Offer, What Members Use, and Whether It Belongs in the Plan
LFP-11.02 — Benefits Architecture#
Vision benefits are high take-up, low cost, and analytically thinner than dental. The standard employer-sponsored vision plan covers an annual exam and a hardware allowance of $130 to $200 for frames, costing $5 to $15 per member per month. VSP and EyeMed dominate the market. The KFF 2024 Employer Health Benefits Survey found that 82 percent of employers offering health benefits also offer vision coverage. The question is whether vision belongs inside the plan architecture as an integrated screening component or outside it as a standalone hardware subsidy.
The clinical screening value is real. A comprehensive eye exam with retinal imaging can detect diabetic retinopathy before the patient knows they have diabetes. The American Academy of Ophthalmology recommends prompt screening at Type 2 diabetes diagnosis and at least yearly screenings thereafter, yet only about 60 percent of people with diabetes receive them. Retinal examination also detects hypertensive retinopathy before hypertension has been adequately treated. A 2025 systematic review in eClinicalMedicine found that AI applied to retinal imaging predicted hypertension, hyperglycemia, and dyslipidemia with area under the curve values ranging from 0.24 to 0.97, and that arteriolar narrowing and venular widening predict incident coronary heart disease with pooled adjusted hazard ratios of approximately 1.20.
The integration argument for bundled vision is weaker than the corresponding argument for bundled dental. Most TPAs do not have systems that receive screening findings from vision exams and act on them. The vision carrier sends a claim with a procedure code and a diagnosis code, not a structured alert routing the member into diabetes management. The data integration that would make vision a meaningful risk stratification tool does not exist in standard TPA operations.
The economics favor carved out for most small employers. VSP and EyeMed purchasing power and provider networks exceed what a TPA bundled vision benefit provides in most markets. The per-member-per-month differential between models is measured in single-digit dollars; the integration value that would justify bundled vision requires TPA capabilities that most small-group administrators have not built. The voluntary option is defensible for employers with tight cost constraints because vision adverse selection is less severe than dental: employees generally know whether they need glasses, and the population that opts out is not deferring expensive care.
An employer who views the annual eye exam as a medical screening opportunity should pursue bundled vision only if the TPA can demonstrate it routes members with retinal findings into disease management programs. That capability is rare. For most small group employers, carved-out vision is the correct answer.
