Summary
Ready-made spectacles (RMS) offer significant improvements in visual function and quality of life for adults with uncorrected refractive error in India, comparable to custom spectacles (CS). RMS are a viable option, especially where custom options are limited.
Area of Science:
- Ophthalmology
- Public Health
- Optometry
Background:
- Uncorrected refractive error (URE) significantly impacts visual function and quality of life.
- Access to corrective eyewear, particularly custom spectacles (CS), can be limited in certain populations.
- Ready-made spectacles (RMS) present a potential alternative for addressing URE.
Purpose of the Study:
- To compare patient-reported outcomes between ready-made spectacles (RMS) and custom spectacles (CS) in Indian adults with URE.
- To evaluate visual function and quality of life (VFQoL) and participant satisfaction.
- To determine the suitability of RMS for a diverse adult population with refractive errors.
Main Methods:
- Prospective, double-masked, randomized trial with 363 adult participants (aged 18-45 years) with ≥1 diopter of URE.
- Participants were randomized to receive either CS (full correction) or RMS (based on spherical equivalent, limited by inventory).
- Visual function and quality of life (VFQoL) and participant satisfaction were assessed using validated instruments over a 1-month follow-up period.
Main Results:
- Both RMS and CS groups showed significant improvements in VFQoL (mean change: 3.23 logits for RMS vs. 3.61 logits for CS) and patient satisfaction.
- In multivariable analysis, CS showed a slightly greater improvement in VFQoL compared to RMS (+0.45 logits).
- Individuals with astigmatism greater than 2.00 D experienced significantly less improvement in VFQoL, irrespective of spectacle type.
Conclusions:
- Ready-made spectacles provide substantial improvements in VFQoL and comparable patient satisfaction to custom spectacles at 1-month follow-up.
- RMS are a suitable and effective option for the majority of individuals with URE in the study population.
- Custom spectacles may offer additional benefits for individuals with higher degrees of astigmatism, and RMS are valuable where custom options are inaccessible or unaffordable.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
