Latent hyperopia is farsighted power hidden by active accommodation during refraction. Cycloplegic drops relax accommodation to reveal the full prescription. Fogging and plus-lens tests also help detect masked hyperopia. Symptoms include eyestrain, headaches, and near blur.

Binocular balance, PRA/NRA, and accommodative testing add context. Results guide near adds or vision therapy when appropriate.
It temporarily relaxes the ciliary muscle so hidden hyperopia becomes measurable. This prevents over-minus prescriptions. Children and young adults often need cycloplegia for accuracy. Safety and timing follow clinical protocols.
Fogging adds plus power to relax accommodation during testing. It helps avoid stimulating extra focus while measuring refraction. The technique is adjusted until clarity is achieved. It complements, not replaces, cycloplegia.
Near fatigue, headaches, and intermittent blur are common. Reading distance creeps farther away to stay clear. Children may avoid near tasks. A full exam confirms the cause.
Glasses with appropriate plus power reduce strain. Near adds or part-time wear may be recommended. Follow-up monitors comfort and school performance. Therapy is considered in selected cases.
Latent hyperopia is farsightedness that is masked by the eye's ability to accommodate. It becomes apparent only when the focusing system is relaxed or fatigued.
Yes. Continuous focusing effort to overcome latent hyperopia can lead to eyestrain, headaches and blurred vision, particularly after prolonged near work.
Management may include prescription glasses or contact lenses to reduce the need for constant accommodation. In children, cycloplegic refraction helps reveal the full hyperopic prescription.
