For most eye modeling jobs, the skin around your eyes like your cheeks, forehead and eyelids will also be visible. Take actions to keep your skin healthy and tight. Consider following beauty and lifestyle regimens that prevent dark circles, bags, cuts, scars, bruises and acne. You may also choose not to get facial tattoos or dermal piercings, as they may prevent you from booking certain jobs. Consider avoiding skincare or makeup products to which you're allergic and trying new products on another area of skin like an arm or leg before trying them on your face to avoid irritation. 4. Get your eyebrows done Optic neuropathies, such as glaucoma, anterior ischaemic optic neuropathy (AION), traumatic optic neuropathies, optic neuritis, etc., need new treatment options, which in turn require the development of disease models [ 1]. However, the pathophysiological mechanisms of these diseases are not fully understood; therefore, developing an animal model is a tough challenge. Moreover, due to the physiological differences, animal models differ significantly from human diseases [ 2]. For example, rodents’ eyes do not have maculae or foveae, and 85–90% of their optic nerve axons decussate to the other side of the brain [ 1]. On the other hand, monkeys’ anatomy of the retina and optic nerve is almost identical to that of human eyes. Still, monkey breeding is complicated, very expensive, and time-consuming; therefore, the number of tests performed on individual animals is limited. As a result, monkeys are often used in the stage just before clinical trials on humans [ 1].

The R28 immortalized retinal precursor cell line originating from postnatal day 6 rat retinal culture has been frequently used in in vitro and in vivo studies [ 32]. R28 provides an important system for understanding retinal cell behavior aspects such as differentiation, cytotoxicity, light stimulation, and neuroprotection. Although R28 originated from single clones, they remained highly heterogenous, suggesting the precursor character of these cells [ 32]. This cell model has been used in various toxicity experiments in vitro [ 33, 34, 35, 36, 37]. In addition, R28 exerts a high potential for studying the neuroprotective properties of chemical compounds [ 38, 39, 40]. Latanoprost was one of the drugs validated on R28 under the angle of cytoprotective properties [ 33]. Nagra M, Huntjens B. Smartphone ophthalmoscopy: patient and student practitioner perceptions.

Unlike other types of models, eye models don't need to meet a height and weight requirement to be considered for certain positions. Their minimum requirements include having unblemished skin and eyes. Some agencies may have an age requirement—such as 16 or 18—to get representation. Certain clients or agents may list additional requirements on a booking by booking basis. 2. Protect your eyes

Tears lubricate the eyeand are made up of three layers. These three layers together are called the tear film. The mucous layer ismade by the conjunctiva. The watery part of the tears is made by the lacrimal gland. The eye’s lacrimal glandsits under the outside edge of the eyebrow (away from the nose) in the orbit. The meibomian gland makes the oil that becomes another part of the tear film. Tears drain from the eye through the tear duct. When offered bookings, take as many jobs as you can schedule or as many as you feel comfortable doing at one time. This can help build your portfolio and connect you to more people in the industry. The more people you meet, the larger your network becomes, which may help you learn about other opportunities. Consider attending trade shows, beauty expos and other similar events to expand your network. You may also choose to take modeling jobs outside of just eye modeling, such as in fashion or another type of parts modeling, to expand your reach and versatility. 10.

People don't see ultraviolet light, but the human retina can detect it. The lens absorbs it before it can reach the retina. The reason humans evolved to notsee UV light is because the light has enough energy to damage the rods and cones. Insects do perceive ultraviolet light, but their compound eyes don't focus as sharply as human eyes, so the energy is spread out over a larger area.Howcroft, M. J. & Parker, J. A.
