Summary
Most patients reported no significant difference in vision across various lighting conditions. However, factors like vision level, pseudophakia, gender, and ethnicity showed some associations with lighting preferences, though not useful for disease screening.
Area of Science:
- Ophthalmology
- Visual Science
- Patient-Reported Outcomes
Background:
- Perceived visual function is crucial for daily activities.
- Understanding how lighting conditions affect vision is important for patient care.
- Previous research has not extensively explored these influences across diverse patient demographics and ophthalmic conditions.
Purpose of the Study:
- To investigate the impact of different lighting conditions on perceived visual function.
- To analyze these effects in relation to patient age, gender, race, and specific ophthalmic diseases.
Main Methods:
- A prospective survey study involving 722 patients in ophthalmic clinics.
- Patients answered questions comparing vision in bright vs. dim light, indoors vs. outdoors, and different times of day/weather.
- Multivariable multinomial regression models were used to analyze associations with patient demographics and visual acuity.
Main Results:
- Patients with lower vision (LogMAR ≥ 0.3) were more likely to prefer being outdoors.
- Individuals with pseudophakia reported better vision on cloudy days.
- White patients had higher odds of preferring bright light, while males were less likely than females to prefer indoor lighting.
Conclusions:
- Most patients did not perceive significant differences in vision across various lighting conditions.
- Questions about lighting conditions are not effective for disease screening.
- Gender and ethnicity show associations with lighting preferences, warranting further investigation.

8.2K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:17Accessory Structures of the Eye
3.0K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

01:25Glaucoma: Overview
1.1K
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...

01:27Open Angle Glaucoma: Treatment
859
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
986
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...
