Summary
Highly aspherical lenslet (HAL) spectacle lenses, popular for myopia control, do not significantly impact visual field sensitivity. This study found no clinically relevant changes in detection sensitivity within 30° eccentricity compared to single vision lenses.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Spectacle lenses with lenslets are increasingly used for myopia control.
- Their efficacy and minimal impact on visual performance are established.
- A key question remains regarding their effect on visual field sensitivity.
Purpose of the Study:
- To investigate the impact of highly aspherical lenslet (HAL) spectacle lenses on visual field sensitivity.
- To determine if lenslets affect the detection of static targets in the visual field.
Main Methods:
- Automated static perimetry (Goldman perimeter target III) was used.
- Detection sensitivity was measured at 76 locations within 30° eccentricity.
- Twenty-one adult subjects compared HAL lenses with single vision lenses (SVL).
Main Results:
- Mean sensitivity differences between HAL and SVL ranged from -1.14 dB to 1.28 dB.
- A statistically significant increase in sensitivity (1.1 dB) was observed at one location (30° temporal).
- No significant correlation was found between sensitivity differences and age or refractive error.
Conclusions:
- Highly aspherical lenslet (HAL) spectacle lenses do not alter overall visual field detection sensitivity.
- The observed minor changes are unlikely to be clinically significant.
- HAL lenses maintain visual field sensitivity comparable to single vision lenses.

01:16Focusing of Light in the Eye
3.0K
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...

01:27Open Angle Glaucoma: Treatment
520
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.

01:28Angle Closure Glaucoma: Treatment
613
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...

01:25Glaucoma: Overview
679
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
